Last Updated: 06/2007

MAKINGPHONECALLS

HANDSET, SPEAKERPHONE ANDHEADSETMODE

Handset can be toggled between Speaker and Headset. To switch between Handset and Speaker/Headset, press the Hook Flash in the handset cradle or press the SPEAKER button.

MULTIPLESIP ACCOUNTS ANDLINES

The GXP2020 can support up to 6 independent SIP accounts. Each account is capable of independent SIP server, user and NAT settings. Each of the 6 line buttons is “virtually” mapped to an individual SIP account. The name of each account is conveniently printed next to its corresponding button. In off-hookstate, select an idle line and the name of the account (as configured in the web interface) is displayed on the LCD and a dial tone is heard.

For example: Configure the first three of the six SIP accounts as “BenjiSIP”, “SIPnGO”, “IbenSIP”, respectively and ensure each is active and registered. When LINE1 is pressed, you will hear a dial tone and see “BenjiSIP” on the LCD display; when LINE2 is pressed, you will hear a dial tone and see “SIPnGo” on the LCD display; when LINE3 is pressed, you will hear a dial tone and see “IbenSIP” on the LCD display.

To make a call, select the line you wish to use. The LED will light up green. Switch lines before dialing by pressing the same LINE button one or more times. If you continue to press one LINE, the selected account will circulate among the registered accounts.

For example: when LINE1 is pressed, the LCD displays “BenjiSIP”; If LINE1 is pressed twice, the LCD displays “SIPnGo” and the subsequent call will be made through SIP account 2 - SIPnGo.

Incoming calls to a specific account will attempt to use its corresponding LINE if it is not in use. When the “virtually” mapped line is in use, the GXP2020 will flash the next available LINE (from left to right) in red. A line is ACTIVE when it is in use and the corresponding LED is solid red.

COMPLETINGCALLS

There are six ways to complete a call:

1.DIAL: To make a phone call.

Take Handset/SPEAKER/Headset off-hook

MAKINGCALLS USINGIP ADDRESSES

Direct IP calling allows two phones to talk to each other in an ad hoc fashion without a SIP proxy. VoIP calls can be made between two phones if:

both phones have public IP addresses, or

both phones are on a same LAN/VPN using private or public IP addresses, or

both phones can be connected through a router using public or private IP addresses (with necessary port forwarding or DMZ)

To make a direct IP call, please follow these steps:

1.Press MENU button to bring up MAIN MENU.

2.Select “Direct IP Call” using the arrow-keys.

3.Press OK to select.

4.Input the 12-digittarget IP address. (Please see example below).

5.Press OK key to initiate call.

To make a quick IP call, please see next section.

For example: If the target IP address is 192.168.1.60 and the port is 5062 (e.g. 192.168.1.60:5062), input the following:192*168*1*60#5062 - The start “* ” key represent the dot“.” ; The hash “#” key represent colon “:”. Press OK to dial out.

QUICKIP CALLMODE

The GXP2020 also supports Quick IP call mode. This enables the phone to make direct IP-calls,using only the last few digits (last octet) of the target phone’sIP-number.

This is possible only if both phones are in under the same LAN/VPN. This simulates a PBX function using the CMSA/CD without a SIP server. Controlled static IP usage is recommended.

Setting up the phone to make Quick IP calls

To enable Quick IP calls, the phone has to be setup first. This is done through the web-setupfunction. In the “Advanced Settings” page, set the "Use QuickIP-callmode to YES. When #xxx is dialed, wherex is0-9andxxx <=255, a direct IP call to aaa.bbb.ccc.XXX is completed. “aaa.bbb.ccc” is from the local IP addressregardless of subnet mask. The numbers #xx or #x are also valid. The leading 0 is not required (but OK).

For example:

192.168.0.2 calling 192.168.0.3 --dial #3 follow by SEND or # 192.168.0.2 calling 192.168.0.23--dial #23 follow by SEND or # 192.168.0.2 calling 192.168.0.123--dial #123 follow by SEND or #

192.168.0.2: dial #3 and #03 and #003 results in the same call --call 192.168.0.3

NOTE: If you have a SIP Server configured, a DirectIP-IPstill works. If you are using STUN, the DirectIP-IPcall will also use STUN. Configure the “Use Random Port” to “NO” when completing Direct IP calls.

This controls the silence suppression/VAD feature of the audio codec G.723 and G.729. If set to “Yes”, when silence is detected, a small quantity of VAD packets (instead of audio packets) will be sent during the period of no talking. If set to “No”, this feature is disabled.

This field contains the number of voice frames to be transmitted in a single Ethernet packet (be advised the IS limit is based on the maximum size of Ethernet packet is 1500 byte (or 120kbps)).

When setting this value, be aware of the requested packet time (ptime, used in SDP message) is a result of configuring this parameter. This parameter is associated with the first codec in the above codec Preference List or the actual used payload type negotiated between the 2 conversation parties at run time.e.g., if the first codec is configured as G.723 and the “Voice Frames per TX” is set to 2, then the “ptime” value in the SDP message of an INVITE request will be60ms because each G.723 voice frame contains 30ms of audio. Similarly, if this field is set to 2 and the first codec is G.729 or G.711 or G.726, then the “ptime” value in the SDP message of an INVITE request will be20ms.

If the configured voice frames per TX exceeds the maximum allowed value, the IP phone will use and save the maximum allowed value for the corresponding first codec choice. The maximum value for PCM is 10 (x10ms) frames; for G.726, it is 20 (x10ms) frames; for G.723, it is 32 (x30ms) frames; for G.729/G.728, 64 (x10ms) and 64 (x2.5ms) frames respectively.

Please be careful when editing these parameters. Adjusting these parameters will also change the dynamic jitter buffer. The GXP2020 has a patent dynamic jitter buffer handling algorithm. The jitter buffer range is 20 ~ 200 ms.

Grandstream recommends using the default settings provided. Grandstream does not recommend adjusting these parameters if you are an average user. Incorrect settings will affect the voice quality. Please refer to the Codec FAQ at http://www.grandstream.com/FAQ/FAQ-Codec.pdf for more technical detail.

This field defines the layer 3 QoS parameter. It is the value used for IP Precedence or Diff-Servor MPLS. Default value is 48.

This contains the value used for layer 2 VLAN tag. Default setting is blank.

Default is 4 seconds.

This parameter allows users to configure the “#” key as the “Send” (or “Dial”) key. If set to “Yes”, the “#” key will immediately send the call. In this case, this key is essentially equivalent to the “(Re)Dial” key. If set to “No”, the “#” key is included as part of the dial string.

This parameter defines the local RTP-RTCPport pair used to listen and transmit. It is the base RTP port for channel 0. When configured, channel 0 will use this port _value for RTP and the port_value+1 for its RTCP; channel 1 will use port_value+2 for RTP and port_value+3 for its RTCP. The default value is 5004.

This parameter, when set to “Yes”, will force random generation of both the local SIP and RTP ports. This is usually necessary when multiple GXP2020s are behind the same NAT. Default is No.

This parameter specifies how often the GXP2020 sends a blank UDP packet to the SIP server in order to keep the “hole” on the NAT open. Default is 20 seconds.

NAT IP address used in SIP/SDP message. Default is blank.

IP address or Domain name of the STUN server. STUN resolution result will display in the STATUS page of the Web UI.

This radio button will enable GXP2020 to download firmware or configuration file through either HTTP or local TFTP server. Choices are mutually exclusive.

This is the IP address of the configured TFTP server. If selected and it is non-zeroor not blank, the GXP2020 will attempt to retrieve a new configuration file or new code image from the specified TFTP server at boot time. It will make up to 3 attempts before timeout and then it will start the boot process using the existing code image in the Flash memory. If a TFTP server is configured and a new code image is retrieved, the new downloaded image will be verified and then saved into the Flash memory.

Note: Grandstream strongly recommends that the user upgrade firmware locally in a LAN environment if using TFTP to upgrade. Please do NOT interrupt the TFTP upgrade process (especially the power supply) as this will damage the device.

The HTTP server URL used for firmware upgrade and configuration via HTTP. For example: http://provisioning.mycompany.com:6688/Grandstream/1.1.1.14.

Here “:6688” is the specific TCP port that the HTTP server is using; omit if using default port 80.

Note: If Auto Upgrade is set toNo, GXP2020 will only perform HTTP download once at boot up.

This function is used by ITSP. End user should NOT touch these parameters.

Default is No. Choose “Yes” to enable automatic HTTP upgrade and provisioning.

In “Check for upgrade every” field, enter the number of minutes to check the HTTP server for firmware upgrade or configuration changes. When set to “No”, the phone will only perform HTTP upgrade and configuration check once at boot up.

Enable the XML phonebook via TFTP or HTTP. Define XML server path and download speed.

Enable XML Idle Screen via TFTP or HTTP. Define XML server path.

NAT related info (INFO level)

sent or received SIP message (DEBUG level)

SIP message summary (INFO level)

inbound and outbound calls (INFO level)

registration status change (INFO level)

negotiated codec (INFO level)

Ethernet link up (INFO level)

SLIC chip exception (WARNING and ERROR levels)

memory exception (ERROR level)

The Syslog uses USER facility. In addition to standard Syslog payload, it contains the following components: GS_LOG: [device MAC address][error code] error message

For example: May 19 02:40:38 192.168.1.14 GS_LOG: [00:0b:82:00:a1:be][000]. Ethernet link is up.

This parameter defines the URI or IP address of the NTP (Network Time Protocol) serve. It is used to display the current date/time.

Caller ID must be configured. Select a Distinctive Ring Tone 1 through 3 for a particular Caller ID. The GXP will ONLY use selected ring tones for particular Caller IDs. For all other calls, the GXP will use System Ring Tone. When selected and no Caller ID is configured, the selected ring tone will be used for all incoming calls.

Default is No. If set to Yes, the call waiting will be disabled.

Dial an IP address under the same LAN/VPN segment by entering the last octet in the IP address.

In the Advanced Settings page there is an option "Use Quick IP-callmode". Default setting isNo. When set to YES, and #XXX is dialed, where X is0-9and XXX <=255, phone will make direct IP call to aaa.bbb.ccc.XXX where aaa.bbb.ccc comes from the local IP address REGARDLESS of subnet mask.

#XX or #X are also valid so leading 0 is not required (but OK). See Quick IP Call Mode for details.

If set to “Yes”, the configuration changes via keypad are disabled.

This parameter activates the NAT traversal mechanism. If activated (by choosing “Yes”) and a STUN server is also specified, the phone performs according to the STUN client specification. Using this mode, the embedded STUN client detects if and what type of NAT/Firewall configuration is used. If the detected NAT is a Full Cone, Restricted Cone, or a Port-RestrictedCone, the phone will use its mapped public IP address and port in all of its SIP and SDP messages. If the NAT Traversal field is set to “Yes” with no specified STUN server, the GXP2020 will periodically (every 20 seconds or so) send a blank UDP packet (with no payload data) to the SIP server to keep the “hole” on the NAT open.

Default is No. When set to “Yes” a SUBSCRIBE for Message Waiting Indication will be sent periodically.

SIP Extension to notify SIP server that the unit is behind the NAT/Firewall.

When configured, user can access messages by pressing “MSG” button. This ID is usually the VM portal access number.

This parameter specifies the mechanism to transmit DTMF digit. There are 3 supported modes: in audio which means DTMF is combined in audio signal (not very reliable with low-bit-ratecodec), via RTP (RFC2833), or via SIP INFO.

Default is No. Use only if proxy supports 484 response.

Sets the prefix added to each dialed number.

Default is No. If set to “Yes”, Call transfer, Call Forwarding &Do-Not-Disturbare supported locally provided ITSP support those features.

The SIP Session Timer extension enables SIP sessions to be periodically “refreshed” via a SIP request (UPDATE, or re-INVITE.Once the session interval expires, if there is no refresh via a UPDATE orre-INVITEmessage, the session is terminated.

Session Expiration is the time (in seconds) at which the session is considered timed out, provided no successful session refresh transaction occurs beforehand. The default value is 180 seconds.

Defines the minimum session expiration (in seconds). Default is 90 seconds.

If set to “Yes”, the phone will use session timer when it makes outbound calls if remote party supports session timer.

If selecting “Yes”, the phone will use session timer when it receives inbound calls with session timer request.

If set to “Yes”, the phone will use session timer even if the remote party does not support this feature. If set to “No”, the session timer is enabled only when the remote party supports this feature. To turn off Session Timer, select “No” for Caller Request Timer, Callee Request Timer, and Force Timer.

As a Caller, select UAC to use the phone as the refresher, or UAS to use the Callee or proxy server as the refresher.

As a Callee, select UAC to use caller or proxy server as the refresher, or UAS to use the phone as the refresher.

Software Upgrade & Customization

Software (or firmware) upgrades are completed via either TFTP or HTTP. The corresponding configuration settings are in the ADVANCED SETTINGS configuration page.

FIRMWAREUPGRADE THROUGHTFTP/HTTP

To upgrade via TFTP or HTTP, select TFTP or HTTP upgrade method. “Upgrade Server” needs to be set to a valid URL of a HTTP server. Server name can be in either FQDN or IP address format. Here are examples of some valid URLs.

firmware.mycompany.com:6688/Grandstream/1.0.0.18

168.75.215.189

There are two ways to set up the Upgrade Server to upgrade firmware: Key Pad Menu and Web Configuration Interface.

KEYPADMENU

To configure the Upgrade Server via Key Pad Menu options, select “Config” from the Main Menu, then select “Upgrade”. Under this sub Menu, user can edit Upgrade Server in either an IP address format or FQDN format. Choose “Save and use TFTP” or “Save and use HTTP” to select upgrade method. Select “Reboot” from the Main Menu to reboot the phone.

WEBCONFIGURATIONINTERFACE

To configure the Upgrade Server via the Web configuration interface, open the web browser. Enter the GXP2020 IP address. Enter the admin password to access the web configuration interface. In the ADVANCED SETTINGS page, enter the Upgrade Server’s IP address or FQDN in the “Upgrade Server” field. Select TFTP or HTTP upgrade method. Update the change by clicking the “Update” button. “Reboot” or power cycle the phone to update the new firmware.

During this stage, the LCD will display the firmware file downloading process. If a firmware upgrade fails for any reason (e.g., TFTP/HTTP server is not responding, there are no code image files available for upgrade, or checksum test fails, etc), the phone will stop the upgrading process and re-bootusing the existing firmware/software.

Firmware upgrades take around 20 seconds in a controlled LAN or 2-3minutes over the Internet. Grandstream recommends completing firmware upgrades in a controlled LAN environment whenever possible.

NOLOCALTFTP SERVER

For users who do not have local TFTP server, Grandstream provides a NAT-friendlyTFTP server on the public Internet for users to download the latest firmware upgrade automatically. Please check the Support/Download section of our website to obtain this TFTP server IP address:http://www.grandstream.com/y-firmware.htm .Each product has a unique TFTP server address.

Alternatively, download and install a free TFTP or HTTP server to the LAN to perform firmware upgrades. A free Windows version TFTP server is available: http://support.solarwinds.net/updates/NewcustomerFree.cfm.

DIRECTIONS TO CONFIGURE LOCAL TFTP:

1.Unzip the file and put all of them under the root directory of the TFTP server.

2.The PC running the TFTP server and the GXP2020 should be in the same LAN segment.

3.Go to File ->Configure->Security to change the TFTP server's default setting from "Receive Only" to "Transmit Only" for the firmware upgrade.

4.Start the TFTP server, in the phone’s web configuration page

5.Configure the Firmware Server Path with the IP address of the PC

6.Update the change and reboot the unit

User can also choose to download the free HTTP server from http://httpd.apache.org/ or use Microsoft IIS web server.

NOTE:

When GXP2020 phone boots up, it will send TFTP or HTTP request to download configuration file “cfg000b82xxxxxx”, where “000b82xxxxxx” is the MAC address of the GXP2020 phone. This file is for initial provisioning purposeonly.

For normal TFTP or HTTP firmware upgrades, the following error messages in a TFTP or HTTP server log can be ignored: “TFTP Error from [IP ADRESS] requesting cfg000b82023dd4 : File does not exist. Configuration File Download

CONFIGURATIONFILEDOWNLOAD

The GXP2020 can be configured via Web Interface as well as via Configuration File through TFTP or HTTP. “Upgrade Server” is the TFTP or HTTP server path for the configuration file. It needs to be set to a valid URL, either in FQDN or IP address format.

A configuration parameter is associated with each particular field in the web configuration page. A parameter consists of a Capital letter P and 2 to 3 (Could be extended to 4 in the future) digit numeric numbers. i.e., P2 is associated with “Admin Password” in the ADVANCED SETTINGS page. For a detailed parameter list, please refer to the corresponding configuration template of the firmware.

Once the GXP2020 boots up (or re-booted),it will request a configuration file named “cfgxxxxxxxxxxxx”, where “xxxxxxxxxxxx” is the MAC address of the device, i.e., “cfg000b820102ab”. The configuration file name should be in lower cases.

MANAGINGFIRMWARE ANDCONFIGURATIONFILEDOWNLOAD

When “Automatic Upgrade” is set to “Yes”, a Service Provider can use P193 (Auto Check Interval, in minutes, default and minimum is 60 minutes) to have the devices periodically check for upgrades at prescheduled time intervals. By defining different intervals in P193 for different devices, a Server Provider can manage and reduce the Firmware or Provisioning Server load at any given time.
