MultiVOIP 200 User Guide

Introduction

Welcome to Multi-Tech's new voice/fax gateway, the MultiVOIP, model MVP200. The MultiVOIP 200 allows analog voice and fax communication over a traditional data communications/data networking digital Internet. Multi-Tech’s new voice/fax gateway technology allows voice and fax communication to be transmitted, with no additional expense, over your existing communications Internet, which has traditionally been data-only. To access this free voice and fax communication, all you have to do is connect the MultiVOIP 200 to a phone or to your existing in-house phone switch and then to your existing Internet connection. Once configured, the MultiVOIP 200 allows voice and fax to travel down the same path as your traditional data communications.

The MultiVOIP 200 supports the H.323 standards-based protocol enabling your MultiVOIP 200 to participate in real-time conferencing with other third-party VOIP Gateways or endpoints that support the H.323 protocol (e.g., Microsoft Netmeeting and receive calls, how endpoints negotiate a common set of audio and data capabilities, how information is formatted and sent over the network, and how endpoints communicate with their respective Gatekeepers. Gatekeeper software is optional and if present in a network, it typically resides on a designated PC. It acts as the central point for all calls within its zone and provides call control services to all registered endpoints. In addition, Gatekeepers can perform bandwidth management through support for Bandwidth Request, Confirm, and Reject messages.

Note: A zone consists of all H.323 endpoints that are under the Gatekeeper’s control.

). The H.323 standard defines how endpoints make

The MVP200 is designed with two voice/fax channels (which offer three voice/fax interfaces on each channel), a 10 Mbps Ethernet LAN interface, and a command port for configuration.

System management is provided through the command port using bundled Windows® software which provides easy-to-use configuration menus and a comprehensive Help system.

T ypical Application

Before Voice Over IP (VOIP), i.e., voice over the Internet, a corporate office had a data connection to the Internet and a voice connection to the public switched telephone network (PSTN). With VOIP, the two networks can be tied together. To accomplish this, a MultiVOIP 200 is connected between the public switched telephone network and the data network at the corporate office as shown in the typical VOIP application in Figure 1-2. The remote branch office has two standard telephones connected to the MultiVOIP and its Ethernet connection is plugged into the hub on the data network. The data network is connected via a router to the Internet. In our typical application, a user at the corporate office picks up a telephone connected to their local telephone switch (PBX) and calls the remote branch office by dialing extension 4124 on the corporate MultiVOIP. When the second dial tone is heard, the caller then dials extension 301 at the remote branch office. The remote branch office telephone rings and a voice conservation takes place.

Figure 1-2. Typical VOIP Application

To set up this VOIP network, a MultiVOIP 200 at the corporate office is connected between the data network and the corporate telephone switch (PBX). To connect the MultiVOIP 200 to the data network, an Ethernet cable is connected to the Ethernet port on the unit and the other end is plugged into a hub on the data network. On the phone side, two phone cords are connected to two FXO jacks on the back of the MultiVOIP 200 and attached to two station lines on the phone switch. These two lines on the PBX occupy phone extensions 4124 and 4125.

To set up a MultiVOIP 200 at the remote branch office, the Ethernet jack on the MultiVOIP 200 is connected to the hub and the two analog phones are connected by phone cords to the FXS jacks on the MultiVOIP 200.

To configure a MultiVOIP 200, the COM port of a PC is connected to the Command port on the MultiVOIP 200. Configuration software is loaded onto your PC and your unique LAN parameters must be established. The configuration software is based on a standard Windows Graphical User Interface (GUI) which simplifies your selection process to a single parameter group within a dialog box. For example, your LAN IP parameters are contained on a single dialog box (see below). You can configure your network IP address and mask for the MultiVOIP 200 and the gateway address for the corporate router on the same dialog box.

For your corporate MultiVOIP, the Ethernet Frame Type is Type II, the IP Address is 201.22.122.118, the Subnet Mask Address is 255.255.255.128, and the router Gateway Address is 201.22.122.1. The remote branch office would have the same Frame Type, a LAN IP address of 206.25.124.120 and a

Chapter 1 - Introduction and Description

Gateway Address of 206.25.124.110. Once the LAN parameters are established, you can set up the voice channel parameters.

The channel setup parameters define the voice side of the MultiVOIP, that is, the voice channel interface; FXS (Ground and Loop Start) are for connecting to a standard analog telephone set, FXO (Foreign Exchange Office) interface connects to the station side of a PBX, and E&M (Ear and Mouth) connects to the trunk side of the PBX. Along with each interface there are additional parameters that need to be considered, such as for FXO, the dialing options for DTMF (Touchtone) or Pulse, the method of disconnecting (Current Loss or Tone Detection), and for E&M, signaling, mode, and the wink timer settings in milliseconds.

Additional channel setup parameters cover the voice coder, DTMF gain, voice gain, and faxing in the Voice/Fax tab of the Channel Setup dialog box. The most important parameter in this group is to ensure that the voice coder is the same for all MultiVOIPs in the network. The Billing/Misc tab handles the billing options, automatic disconnect options, and the dynamic jitter buffer options. The jitter options in this tab handle voice break up which can be particularly disruptive to voice communications. For the most part, these parameters can remain in their default values. The Regional tab defines the country or region the MultiVOIP is being used in.

In our typical application, you would configure the corporate office channel parameters for an FXO interface. With this interface, the defaults for the Dialing Options and the type of Disconnect could remain as the defaults. For the remote branch office, the interface would be FXS with Loop Start being used in most cases.

MultiVOIP 200 User Guide

Once you have completed channel setup, you will need to add the phone numbers to the phone directory database. Before you set up the phone directory database, you need to consider how the database is going to be used; are you going to have an H.323 Gatekeeper setup your call sessions or are you going to control your call sessions using the proprietary phone book. The H.323 Gatekeeper acts as the central point for all calls within its zone and provides call control services to registered endpoints. If you choose the proprietary phone book, you establish a Host-Client relationship where the Host MultiVOIP maintains the phone directory and downloads the directory to each Client unit.

The decision on building the phone directory database is contained in the Phone Directory Database dialog box. Before you choose how the data base is going to be used, here are a couple of things to keep in mind; (1) If a Gatekeeper is employed in the network, you need to choose the Gatekeeper option. You can not mix the Proprietary PhoneBook with the Gatekeeper. If you choose the Gatekeeper option you can communicate with other third party endpoints that support H.323 (e.g., Microsoft Netmeeting). (2) If you choose the Proprietary PhoneBook, you establish a Host-Client relationship in that the Host MultiVOIP maintains the phone directory database. All of the phone numbers are listed in the data base so that if you want to communicate with someone in your VOIP network, you can see the phone number in your data base. Everytime you bring up your MultiVOIP the current phone directory is downloaded to your MultiVOIP.

The Gatekeeper is a separate application that can operate on a network pc and provides all the controls needed to create, control, and manage an H.323 network zone. The H.323 network zone is all the endpoints (terminals and gateways (MultiVOIPs)) that are registered with the gatekeeper. The gatekeeper functions are address translation from LAN aliases for terminals and gateways to IP addresses as defined in the RAS (Registration/Admission/Status) specification. The RAS Protocol defines the communication with a gatekeeper and support for RTP/RTCP for sequencing audio packets. The H.323 Gatekeeper also provides call-authorization for both accepting and placing calls in its zone, and certain monitoring features (i.e., call permissioning and address resolution).

So, if you choose the Gatekeeper option, initially you need to communicate with the administrator of the Gatekeeper to register your MultiVOIP. The information you need from the Gatekeeper administrator is the IP address of the Gatekeeper and its port number. Then you need to establish your alias address which includes phone number, channel number, H323 ID which is a name, and your MultiVOIP LAN IP address. The port number is 1720, but if the Gatekeeper uses a different port number, you have to ensure that you use the same port number. The Gatekeeper administrator will then enter your information into the Gatekeeper data base. This concludes the preregisteration.

Now, you can enter your alias address information into the Add/Edit Phone Entry dialog box. For example, if you were setting up the corporate MultiVOIP, you could enter the following information for

Chapter 1 - Introduction and Description

Voice Channel 1. For instance, in our typical application channel 1 of the corporate MultiVOIP uses extension 101. The Description is optional, but can be helpful if you assigned to a particular individual or department, or in this case it defines the channel interface.

The H323 ID that was assigned to this phone number which identifies the office that is using this extension. The IP Address of the Corporate MultiVOIP is 201.022.122.118 and the default port number 1720 is used.

So now when you “come alive”, the Gatekeeper will register you with the above alias address. No other H323 endpoint can use this alias. This is like your own telephone number.

Now, if you choose the Proprietary PhoneBook option in the Phone Directory Database dialog box instead of the Gatekeeper option, the Database Type group would become active and the RAS Parameters group is inactive (greyed out).

Now, lets change the typical application to not have the Gatekeeper control the call session. When you elect to use the Proprietary PhoneBook, you set up a Host-Client relationship. This relationship allows one MultiVOIP to maintain the Phone Directory Database and publish this data base to all MultiVOIP participants in the network. This proprietary data base allows you to see all the participants in your network and provides you with there phone numbers.

Lets again start with the corporate MultiVOIP and we will set up the database so that the corporate MultiVOIP can call the remote branch office and the remote branch office can call the corporate MultiVOIP. To do this, the Phone Directory Database will have two entries for the corporate office and two entries for the Remote Branch Office. Extension 101 at the corporate office is tied to voice channel 1 and extension 102 to channel 2. The Description again ties to the type of interface used on the corporate MultiVOIP (FXO). The Hunt Group in this situation is set for No Hunt. But if you wanted to activate a Hunt Group, i.e., if an extension on the MultiVOIP is busy and you wanted to look for another extension, you can assign a hunt group to those extensions. So that, say extension 101 is busy, the corporate MultiVOIP would roll over to extension 102.

MultiVOIP 200 User Guide

Again, the IP Address of the corporate MultiVOIP needs to be added and the port number is 1720. This adds phone number 101 of the corporate MultiVOIP to the proprietary data base. Now, to add extension 102 to the proprietary data base, all you have to do is change the Phone Number and Description to support channel 2 of the corporate MultiVOIP. After you have added channel 2, you need to include the two channels at the remote branch office.

The proprietary data base would then appear as in the following dialog box and when the remote branch office MultiVOIP is turned on, the current data base would be down loaded to the remote branch office MultiVOIP.

Chapter 2 - Installation

MultiVOIP 200 User Guide

Installing Y our MultiVOIP 200

The basic steps of installing your MultiVOIP 200 network involve unpacking the units, connecting the cables, and configuring the units using management software (MultiVOIP 200 Configuration). This process results in a fully functional Voice Over IP network. A general description is provided below and detailed instructions are provided in Chapter 3, Software Loading and Configuration.

Installing and Configuring Your MultiVOIP 200

The VOIP administrator must first install the MultiVOIP 200 software and then configure each MultiVOIP 200 for its specific function. During the configuration process, it’s important to note that the Phone Directory Database is configured differently depending on whether or not you have Gatekeeper support on your VOIP network.

If your VOIP network supports Gatekeeper software, you must register all H.323 endpoints with the Gatekeeper. The procedure for doing this is explained in the section “Registering with a Gatekeeper Phone Directory.”

If your VOIP network does not have Gatekeeper software or the Gatekeeper software is not enabled, then you must build a proprietary phonebook with a “Host” MultiVOIP 200 and “Client” MultiVOIP 200s. The “Host” unit includes the assignment of a unique LAN IP address, subnet mask, and Gateway IP address; as well as the selection of appropriate channel interface type for each of the Voice/Fax channels. Once all connections have been made, the VOIP administrator configures the unit and builds the Phone Directory Database that will reside with the Host unit.

Once configuration of the “Host” MultiVOIP 200 has been completed, the administrator moves on to configure the MultiVOIP 200(s) designated as “Client” units. Again, unique LAN IP addresses, subnet masks, and Gateway IP addresses are assigned, and each Voice/Fax channel is configured for the appropriate channel interface type. When this is done, the Phone Directory Database option is set to Client, and the IP address of the Host MultiVOIP 200 is entered. Once all Client units are configured, the process moves on to the “Deploying the VOIP Network” section.

Deploying the VOIP Network

The final phase of the installation is deployment of the network. When the remote MultiVOIP 200s are sent to their remote sites, the remote site administrators need only to connect the units to their LAN and telephone equipment. A full Phone Directory Database (supplied by the Host MultiVOIP 200 Proprietary Phonebook will be loaded into their units within minutes of being connected and powered up. For remote VOIPs that were configured with the Gatekeeper option enabled, each MultiVOIP 200 will be registered with the Gatekeeper (i.e., the Gatekeeper phonebook directory is NOT downloaded to the remote units). The final task of the VOIP administrator or the Gatekeeper administrator is to develop the VOIP Dialing Directory based on the appropriate phone directory database (i.e., the Proprietary phonebook database or the Gatekeeper phonebook database).

Safety Warning Telecom

1. Never install phone wiring during a lightning storm.

2. Never install phone jacks in wet locations unless the jacks are designed for wet locations.

3. This product is to be used with UL and cUL listed computers.

4. Never touch uninsulated phone wires or terminals unless the phone line has been disconnected at the network interface.

5. Use caution when installing or modifying phone lines.

6. Avoid using a phone (other than a cordless type) during an electrical storm. There may be a remote risk of electrical shock from lightning.

7. Do not use the phone to report a gas leak in the vicinity of the leak.

8. To reduce the risk of fire, use only No. 26 AWG or larger Telecommunication line Cord.

Unpacking Your MultiVOIP 200

Remove all items from the box. (See Figure 2-1.)

MultiVOIP 200 User Guide

E&M Jumper Block Positioning Procedure

Each voice/fax channel on the MultiVOIP 200 has a separate E&M jumper block located near the jacks on the back panel of the MultiVOIP 200. Each jumper block has 8 pairs of pins with a jumper plug on three adjacent pairs of pins. The jumper plug must be centered on the E&M type number (see Figure 2-3) that matches the E&M connection for that channel.

MultiVOIP 200’s shipped to Europe, Great Britain, and Ireland have the default setting for the E&M jumper blocks defaulted to a type 5.

Perform the following procedure if you need to move the E&M jumper block from its default (Type 2) for North America or the default type 5 for international markets.

1. Ensure that the external power supply is disconnected from the MultiVOIP 200.

2. Turn the MultiVOIP 200 upside down and remove the cabinet mounting screw at the center back of the cabinet.

3. Return the MultiVOIP 200 to its upright position, then slide the base out the rear of the cabinet. Note: To change a jumper position, lift the jumper plug up off the jumper block, then move it to

the new position, ensuring that the middle jumper of the jumper block is centered on the E&M type number (1,3; 4; or 5) as shown on Figure 2-3. (Note: Numbers are

not

on the board.)

Installing Your MultiVOIP 200 Software

The following installation procedures do not provide every screen or option in the process of installing the MultiVOIP 200 software. It is assumed that a technical person with a thorough knowledge of Windows and the software loading process is doing the installation. Once you have installed the software, you will be instructed on how to configure your MultiVOIP 200, and finally, on how to deploy your MultiVOIP 200. Additional information on the MultiVOIP 200 software is provided in Chapter 4, MultiVOIP 200 Software, and in the on-line Help.

Note: The phonebook directory configuration process is different depending on whether or not you have an enabled H.323 Gatekeeper resident in your network. The section on “Configuring Your MultiVOIP 200” will explain these differences.

If your network includes a Multi-Tech Gatekeeper, Gateways, or other third-party VOIP Gateways or endpoints that support H.323 (for example, Microsoft NetMeeting), you will likely want to install H.323 software.

The MultiVOIP 200 software, Quick Start, and User Guide are contained on the MultiVOIP 200 CD. The CD is auto-detectable, so when you insert it into your CD ROM drive it will start up automatically. When you have finished configuring your MultiVOIP 200, you can view and print the User Guide by clicking on the View Manuals icon and selecting either the Quick Start or this User Guide.

CAUTION: If you are installing a MultiVOIP 200 behind a Firewall, the Firewall must support H.323. Refer to your Firewall user documentation to enable H.323 support.

1. Make certain that your MultiVOIP 200 has been properly cabled and that it is powered on.

2. Insert the MultiVOIP 200 CD into a CD-ROM drive. The CD is auto-detectable, so it starts automatically. It may take 10 to 20 seconds for the Multi-Tech Installation CD screen to appear.

Configuring Your MultiVOIP 200

The following steps provide instructions for configuring your MultiVOIP 200. The configuration sequence includes IP Protocol default setup, Channel setup, and Phone Directory Database setup. The Phone Directory Database setup is configured differently depending on whether or not the Gatekeeper function is available and enabled on the Phone Directory Database dialog box (See Step 26).

11. The IP Protocol Default Setup dialog box is displayed.

The default Frame T ype is TYPE_II. If this does not match your IP network, change the Frame Type by clicking the drop-down arrow and selecting SNAP. The available Frame Type choices are TYPE_II and SNAP.

12. In the Ethernet group, enter the IP Address, Subnet Mask, and Gatewa y Address unique to your IP LAN in the corresponding fields.

The IP address is the unique LAN IP address that is assigned to the MultiVOIP 200, and the Gateway address is the IP address of the device connecting your MultiVOIP 200 to the Internet.

Click OK when you are finished.

13. The Channel Setup dialog box is displayed. The four tabs in this dialog box define the channel interface, voice/fax parameters, billing/miscellaneous parameters, and regional telephone parameters for each channel.

Configure each channel for the type of interface you are connecting to. The Interface tab defaults to Channel 1 in the Select Channel field. To change the channel number, click the drop-down arrow and the list of channels is displayed. Highlight the channel you want to configure.

Note: Feature options are enabled or disabled (grayed out) according to the interface type that you select. The one option available for all interface types is the Inter Digit Time option. This option defines the maximum amount of time that the unit will wait before mapping the dialed digits to an entry in the Phone Directory Database. If too much time elapses between digits, and the wrong numbers are mapped, you will hear a rapid busy signal. If this happens, it will be necessary to hang up and dial again. The default setting is 2 seconds.

MultiVOIP 200 User Guide

14. The Interface group defaults to FXS (Loop Start). Select the interface option that corresponds to the interface type being connected to the Voice/Fax Channel 1 jack on the back panel of the MultiVOIP 200.

FXS (Loop Start): If a station device; e.g., an analog telephone, fax machine, or KTS (Key Telephone System) is connected to the Voice/Fax connector on the back of the unit, FXS (Loop Start) will likely be the correct Interface.

FXS (Ground Start): If the station device uses ground start, then choose the FXS (Ground Start) option. Refer to the device’s user documentation.

For both FXS Loop Start and FXS Ground Start , the Ring Count FXS window allows you to set the maximum number of rings output on the FXS interface before hanging up and releasing the line to another call. The default setting is 8 rings.

Note: Zero (0) means no rings - caller hears a busy tone. FXO: If you are using an analog extension from your PBX, then choose the FXO option. Check

with your in-house phone personnel to verify the connection type. If FXO is selected, the Dialing Options Regeneration, Flash Hook Timer, and Ring Count

groups are enabled. Check with your local in-house phone personnel to verify whether your local PBX dial signaling is Pulse or tone (DTMF). Then, set the Regeneration option accordingly. The Flash Hook Timer allows you to enter the time, in milliseconds, for the duration of the flash hook signals output on the FXO interface. The default setting is 600 milliseconds. The Ring Count FXO window allows you to set the number of rings received on the FXO interface before the MultiVOIP 200 answers the incoming call. The default setting is 2 rings.

Note: Zero (0) means that the MultiVOIP 200 never answers. For FXO-to-FXO communications, you can enable a specific type of FXO Disconnect; Current

Loss, Tone Detection, or Silence Detection. (Check with your in-house phone personnel to verify the preferred type of disconnect to use.) Enabling Tone Detection activates the Disconnect Tone Sequence options. For Disconnect T one Sequence, you can select from dropdown lists either one or two tones that will cause the line to be disconnected; the person hanging up a call must then hit the key(s) that will produce those tones. For Silence Detection, select One Way or Two Way, then set the timer for the number of seconds of silence before disconnect. Note that the default value of 15 seconds may be shorter than desired for your application.

E&M: If you are connecting to an analog E&M trunk on your PBX, then choose the E&M interface option to enable the E&M Options group. Check with your local in-house phone personnel to determine if the signaling is Dial Tone or Wink and if the connection is 2-wire or 4-wire. If Wink signaling is used, then the Wink Timer is enabled with a default of 250 milliseconds. The range of the Wink Timer is from 100 to 350 milliseconds. Consult with your local in-house phone personnel for this timer setting.

Note: After configuring a given channel (1 or 2), you can copy that channel’s configuration by clicking the Copy button and everything on the Interface tab will be copied to the other channel.

15. Repeat the above step to configure the interface type for voice/fax channel 2.

Chapter 3 - Software Loading and Configuration

16. The Voice/Fax tab displays the parameters for the voice gain, DTMF (Dual Tone Multi- Frequency) gain, voice coder, faxing, and advanced features such as Silence Compression, Echo Cancellation, and Forward Error Correction.

17. You can set up the input and output voice gain so that the volume can be increased or decreased. Input gain modifies the level of the audio coming in to the voice channel before it is sent over the Internet to the remote MultiVOIP 200; and, output gain modifies the level of the audio being output to the device attached to the voice channel. Make your selections from the Input and Output drop-down lists in the Voice Gain group. The valid range is +31dB to –31dB with a recommended/default value of 0.

You can also set up the DTMF gain (or output level in decibels - dB) for the higher and lower frequency groups of the DTMF tone pair. Make your selections in the drop-down lists in the DTMF Gain group. When DTMF Out of Band is checked, the unit reproduces the DTMF tones instead of passing them through.

Note: Only change the DTMF gain under the direction of Multi-Tech Technical Support supervision.

18. To change the voice coder, first select the channel by clicking the Select Channel down arrow (highlighting the channel number) then click Manual in the Coder group. To select the appropriate coder, click the Selected Coder down arrow and highlight your new voice coder entry.

If you changed the voice coder, ensure that the same voice coder is used on the voice/fax channel you are calling; otherwise, you will always get a busy signal.

Note: If you allow the Coder to be selected automatically, then you need to select the Max Bandwidth from the drop-down list. Check with your Network Administrator to determine how

much bandwidth is available.

19. The Fax group enables you to send/receive faxes on the selected voice/fax channel. You can set the maximum baud rate for faxes and the fax volume in the two drop-down lists and change the jitter value in milliseconds.

When receiving fax packets from a remote MultiVOIP 200, it is possible for individual packets to be delayed or received out of order due to traffic conditions on the network. To compensate for this effect, the MultiVOIP 200 uses a Jitter Buffer. The Jitter V alue field allows the MultiVOIP 200 to wait a user-definable period of time, in milliseconds, for delayed or out of order fax packets. The range of allowable Jitter Values is 0 to 400 with a default of 400 milliseconds.

If you do not plan to send or receive faxes on a given voice/fax channel, you can disable faxes in the Fax group.

MultiVOIP 200 User Guide

20. You can enable the voice/fax advanced features by clicking (checking) the silence compression, echo cancellation, or forward error correction options.

The Silence Compression option defines whether silence compression is enabled (checked) for this voice channel. If silence compression is enabled, the MultiVOIP 200 will not transmit voice packets when silence is detected, thereby reducing the amount of network bandwidth that is being used by the voice channel.

The Echo Cancellation option defines whether echo cancellation is enabled (checked) for this voice channel. If echo cancellation is enabled, the MultiVOIP 200 will remove echo which improves the quality of sound.

The Forward Error Correction (FEC) option defines whether forward error correction is enabled (checked) for this voice channel. The FEC feature allows some of the voice packets that were corrupted (or lost) to be recovered. FEC adds an additional 50% overhead to the total network bandwidth consumed by the voice channel.

Note: After configuring a given channel (1 or 2), you can copy that channel’s configuration by clicking the Copy button and everything on the Voice/Fax tab will be copied to the other channel.

21. The Billing/Misc tab displays the parameters for auto call, automatic disconnection, billing options, and dynamic jitter buffer.

If you want to dedicate a local voice/fax channel to a remote voice/fax channel (so you will not have to dial the remote channel), click the Auto Call Enable option in the Auto Call group. Then enter the phone number of the remote MultiVOIP 200 in the Phone Number field.

22. The Automatic Disconnection group provides three options to be used singly or in combination. The Jitter Value defines the average inter-arrival packet deviation (in milliseconds) before the

call is automatically disconnected. Jitter is the inter-arrival packet deviation (phase shift of digital pulses) over the transmission medium that causes voice breakup which can be particularly disruptive to voice communications. The default setting is 20 milliseconds. A higher value means that the voice transmission will be more accepting of jitter. A lower value will be less tolerant of jitter.

Consecutive Packets Lost defines the number of consecutive packets that are lost after which the call is automatically disconnected. The default setting is 30.

Call Duration defines the maximum length of time (in seconds) that a call remains connected before the call is automatically disconnected. The default setting is 180 seconds. A call limit of three minutes may be too short for most configurations. Therefore, you may want to increase this default value.
