Chapter 2: Overview

Overview

Avaya B189 Conference IP Phone is a multiline H.323 IP deskphone that you can use to make
calls and hold conferences with HD quality voice.

The features of the deskphone include a 5 inch touch screen, mute, and volume control
buttons, one On-hook/Off-hook button, and a Phone button. You can navigate the menu only
through the touch screen. Bi-color LEDs provide visual indication of an incoming call, call in
progress, call on hold, and a muted microphone. As the LEDs are visible from all angles, the
deskphone visually alerts the users. Avaya B189 Conference IP Phone has ports for additional
microphones.

About Avaya B189 H.323 Conference IP phones

Avaya B189 Conference IP phones use Internet Protocol (IP) technology with Ethernet line
interfaces and support the H.323 protocol. These phones support DHCP, HTTP, and HTTPS
to get customized settings and to download new versions of software for the phones.

The H.323 standard provides real time transmission for audio, video, and data communications
over a packet network.

An Avaya B189 Conference IP phone protocol stack comprises of the following:

• H.225 for registration, admission, status (RAS), and call signaling

• H.245 for control signaling

• Real Time Transfer Protocol (RTP) and Secure Real Time Transfer Protocol (SRTP)

• Real Time Control Protocol (RTCP) and Secure Real Time Control Protocol (SRTCP)

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.

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 December 2013 15

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

Application Files on page 49.

Registration with the call server

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

Telephone Software and

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 December 2013

Comments? [e-mail]

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.

Error conditions

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.

For more information, see your Avaya server administration documentation and Administration
for Network Connectivity for Avaya Communication Manager, 555-233-504.

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.

Call server administration

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

Phone administration on Avaya Aura® Communication Manager

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.

Related topics:

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

up customized groups on page 52. You can administer the GROUP ID parameter on page

3 of the Change Station Form.
