want.

Initialization process overview

The initialization process includes an information exchange when the phone registers. This process includes connecting to the network, DHCP processing, VPN connection, file downloads, and phone registration with the call server.

You must administer all equipment properly prior to initialization.

SeeImplementing the Avaya B189 Conference IP Phone, 16-604293 for a detailed description of initialization, power-up, and the reset process.

Note:

When you start Avaya B189 Conference IP phone without access to the HTTP server, the conference phone reuses parameters from before the reboot. The phone waits for 60 seconds and starts with the old parameters.

Related topics:

Connection to network on page 15

DHCP processing on page 15

File downloads on page 16

Registration with the call server on page 16

Connection to network

The phone is appropriately installed and powered. After a short initialization process, the phone displays the speed at which it is connected to the network and determines whether to initiate 802.1X network access procedures.

DHCP processing

If an IP address has not been manually configured in the phone, the phone initiates DHCP, as described in Administering the DHCP and File Servers on page 39. Among other data passed to the phone is the IP address of the HTTP or HTTPS server.

Administering Avaya B189 Conference IP Phone

Administration overview and requirements

File downloads

Avaya B189 Conference Phones can download configuration files, language files, and certificate files from either an HTTP or HTTPS server, but they can only download software files from an HTTP server. The phone first downloads an upgrade configuration file, which tells the phone which software files it should use. The phone then downloads a settings configuration file, and based on those settings, it may then download language files and/or certificate files. Finally, the phone will download one or two new software files, depending on whether or not the software in the phone is the same as that specified in the upgrade file. For more information about this download process and settings file, see Telephone Software and Application Files on page 49.

Registration with the call server

The call server referred to in this section is Avaya Aura Communication Manager.

The phone is registered with the call server in two modes, named registration and unnamed registration.

Named registration

In this step, the phone might prompt the user for an extension and password. The phone uses that information to exchange a series of messages with the call server. For a new installation and for full service, the user can enter the phone extension and the password configured on the call server for that particular extension. The information required to restart a phone that was previously registered with an extension number is already stored on the phone.

Unnamed registration

Using this feature, you can register a phone with the call server without an extension, provided the call server also supports this feature. To invoke Unnamed Registration, either enter a null (empty) extension or password or take no action.

A phone registered with Unnamed Registration has the following characteristics:

•Only one call appearance

•No administrable features

•Outgoing calls only, subject to call server Class of Restriction or Class of Service limitations

•Conversion to normal named registration possible by the user entering a valid extension and password.

Other administrable options using parameters

•MCIPADD

You can configure the phone to register to a particular call server by listing the IP addresses in the MCIPADD parameter in DHCP or the 46xxsettings.txt file. The standard

16 Administering Avaya B189 Conference IP Phone

Error conditions

practice is to list the CLANs on the main call server, followed by any Enterprise Survivable Server (ESS) addresses, followed by any Local Spare Processor (LSP). To deviate from this practice, you can list CLANs for multiple main call servers. In general, the phone will start from the beginning of MCIPADD and attempt to register with each IP address in turn, one at a time, until the phone gets a positive response. If MCIPADD is administered, users can register to local call servers.

• UNNAMEDSTAT

You can also administer the phone to avoid unnamed registration and remain unregistered if no extension and password are provided. .

For more information about the installation process, see Implementing the Avaya B189 Conference IP Phone,16-604293.

Error conditions

Assuming proper administration, most of the problems reported by phone users are likely to be LAN-based or Quality of Service. Server administration and other issues can impact user perception of IP phone performance.

For the likely operational problems after you successfully install Avaya B189 Conference IP Phone, see Installing and maintaining Avaya B189 Conference IP Phone, 16-604293.

Communication Manager Administration

Administering the IP interface and addresses

Follow these general guidelines:

•Define the IP interfaces for each CLAN and Media processor circuit pack on the call server that uses the IP Interfaces screen. For more information, see Administration for Network Connectivity for Avaya Communication Manager , 555-233-504.

•On the Customer Options form, verify that the IP Stations field is set to Y (Yes). If it is not set to (Y), contact your Avaya sales representative.

Administering UDP port selection

You can administer the Avaya B189 Conference IP phones from the Avaya Communication Manager Network Region form to support UDP port selection. For information on specific port assignment diagrams, see Implementing Avaya B189 Conference IP Phone.

For information about Avaya Communication Manager implementation, see Administration for Network Connectivity for Avaya Communication Manager, 555-233-504 on the Avaya Support Web site.

Administer the switch to use a port within the proper range for the specific LAN, and the IP deskphone(s) copy that port. If no UDP port range is administered on the switch, the IP deskphone uses an even-numbered port, randomly selected from the interval 4000 to 10000.

Administering RSVP

Avaya B189 Conference IP phones support the Resource Reservation Protocol (RSVP) for IPv4 audio connections only.

You can fully enable RSVP by provisioning CM ip-network-region.

Call server administration

Administering QoS

The Avaya B189 Conference IP Phones support both IEEE 802.1D/Q and DiffServ. Other network-based QoS initiatives such as UDP port selection do not require support by the phones. However, they contribute to improved QoS for the entire network.

Administering IEEE 802.1Q

The Avaya B189 Conference IP phones can simultaneously support receipt of packets that are tagged, or not tagged according to the IEEE 802.1Q standard. To support IEEE 802.1Q, you can administer Avaya B189 Conference IP Phones from the network through LLDP, or by appropriate administration of the DHCP or HTTP/HTTPS servers.

You can administer the IEEE 802.IQ QoS parameters L2QAUD, and L2QSIG through the IP Network Region form. To set these parameters at the switch, see sections on Quality of Service (QoS) and Voice quality administration in Administration for Network Connectivity for Avaya Communication Manager, 555-233-504.

For information on setting these parameters manually, see Implementing Avaya B189 Conference IP Phone.

Administering DIFFSERV

The DiffServ values change to the values administered on the call server as soon as the phone registers. For more information on DiffServ values, see chapter on Network Quality Administration in Administration for Network Connectivity for Avaya Communication Manager, 555-233-504. Unless there is a specific need in your enterprise LAN, do not change the default values.

Administering NAT

Network Address Translation (NAT) usage can lead to problems that affect the consistency of addressing throughout your network. All Avaya B189 Conference IP phones support NAT interworking. Support for NAT does not imply support for Network Address Port Translation (NAPT). The phones do not support communication to the PBX through any NAPT device.

NAT requires specific administration on the call server. A direct Avaya IP phone-to-Avaya IP phone call with NAT requires Avaya Communication Manager Release 3.0 or later software.

Call conferencing

This section provides information about conference call behaviors to consider when administering the call server. The deskphone application presents a user interface, based in part on the deduction of the call state. The following call states might result when the serverbased features interact with the user interface:

•The system parameter Abort Conference Upon Hang-up is set to Yes:

The user must dial and press the Join softkey for the conference to be completed. If the user hangs up during conference setup before pressing Join, the conference is cancelled with the held party remaining on [hard] hold. When the system parameter Abort Conference Upon Hang-up is set to No, the user can hang up immediately after dialing, dial a third party, and then press the Join softkey to have the conference proceed normally.

•The system parameter No Dial Tone Conferencing is set to No and the Conference or Add softkey is pressed:

The call server automatically selects an idle call appearance for the user to dial on. This action allows the user to add the next conferee. When the system parameter No Dial Tone Conferencing is set to Yes, the user must manually select a call appearance after pressing the Conference or Add softkey.

Conferencing behavior changes significantly when you set the Select Line Conferencing to Yes. Then the No Dial Tone Conferencing is automatically set to Yes. Specifically the following scenarios can occur:

•If the user finishes dialing the intended conferee, pressing the initial call appearance completes the conference, as if the Join softkey was pressed.

•If the user has not finished dialing the intended conferee, pressing the initial call appearance cancels the conference set up. Note: The initial conference is placed on soft hold when Conference or Add button is pressed.

•If the user presses the Conference or Add softkey, then immediately presses a hardheld call appearance, the previously held call appearance is retrieved from hold and joins the existing conference.

When you set the system parameter Select Line Conferencing to No, the user can cancel the conference setup by pressing the call appearance on soft hold before pressing Join. Selecting a hard-held call appearance during conference setup establishes the held call as the intended conferee.

For either Select Line Conferencing setting, if the user is in conference setup and answers an incoming call, the incoming call is established as the intended conferee. Then the user must

press Join to add the answered call to the conference. If the user does not want the incoming call to be part of the conference, the user must not answer the call, or the user must answer the call and then hang up before continuing the conference setup. Pressing an in-use call appearance during conference setup makes that call appearance the intended conferee. The Toggle Swap feature works for Conference setup similar to Transfer Setup.

For more information about call transfers, see Administering call transfers.

Phone administration on Avaya Aura® Communication Manager

This section covers Avaya Aura® Communication Manager administration on the Switch Administration Terminal (SAT) or by Avaya Site Administration. You must administer Avaya Aura® Communication Manager on SAT or by Avaya Site Administration to optimize the phone user interface. The SAT provides the system-wide CM form and the particular page or screen that you need to administer for each feature. You need Communication Manager 3.1.2 or later.

Feature-related system parameters on page 23

Feature-related system parameters

In Avaya Communication Manager Release 4.0 and later, you can administer three systemwide parameters. When you administer these parameters on CM, the parameters are automatically downloaded to the phone during registration. You do not need to add these parameters using the settings file or set them locally for each phone. The three system parameters are: SNMP community string, SNMP Source IP addresses, and Craft Access Code (PROCPSWD).

Note:

Commenting out SNMPSTRING in the settings file will not prevent a response to an SNMP query unless the CM administration is also changed accordingly. Also, setting the SNMP flag on the IP-Options form in CM to "n" does not disable SNMP. You must enable the download flag and leave the community string value blank so that when the telephone registers, the SNMPSTRING value will remain null.

To administer these three parameters use Page 3 of the change system-parameters ip-options form.

With Avaya Aura® Communication Manager Release 4.0 and later, you can perform central call server administration of the GROUP parameter on a station-by-station basis. This parameter is then downloaded to each applicable deskphone starting with the next deskphone boot-up. You can use the GROUP Identifier with the 46xxsettings file for administration of specific groups of deskphones. For more information, see Using the GROUP parameter to set up customized groups on page 52. You can administer the GROUP ID parameter on page
