Adding An Ip Softphone - Avaya Communication Manager Administrator's Manual

Managing Telephones
Enabling transmission over IP networks for modem, TTY, and fax
calls
Prerequisites
The ability to transmit fax, modem, and TTY calls over IP trunks or LANs and WANs assumes
that the endpoints sending and receiving the calls are connected to a private network that uses
H.323 trunking or LAN connections between gateways and/or port networks. This type of
transmission also assumes that calls can either be passed over the public network using
ISDN-PRI trunks or passed over an H.323 private network to Communication Manager switches
that are similarly enabled.
As a result, it is assumed that you have assigned, or will assign, to the network gateways the IP
codec you define in this procedure. For our example, the network region 1 will be assigned
codec set 1, which you are enabling to handle fax, modem, and TTY calls.
To enable transmission over IP networks for modem, TTY, and fax calls:
8. Type change ip-codec-set 1. Press Enter.
The IP Codec Set screen appears.
Complete the fields as required for each media type you want to enable. Press Enter.
For more information on modem/fax/TTY over IP, see Administration for Network Connectivity

Adding an IP Softphone

Avaya IP Softphones enable the end user to control telephone calls directly from a personal
computer (PC). An end user can log in remotely to your company's server running Avaya
Communication Manager and then make and receive telephone calls from the telephone
extension.
Avaya IP Softphone supports the following modes:
Road-Warrior
●
You typically use this mode for laptop users who are travelling. In this mode, the PC LAN
connection carries both the call control signaling and the voice path. Because the audio
portion of the voice call is handled by the PC, you must have some kind of audio device
(e.g., handset, headset) PC to provide the audio connection.
