Internet Protocol (IP) Softphones

IP Softphones can turn a PC or a laptop into an advanced telephone. Using the Internet
Protocol (IP) network, you can place calls, take calls, and handle calls on your PC. With certain
exceptions, every feature available for wired-endpoint voice calling is available for IP-based
calling; it supports internetworking with conventional circuit-switched stations and trunks.
There are three softphone models that are fixed at the time of purchase and do not change
afterward:
Avaya IP Softphone (for additional information, go to http://www.avaya.com/support, click
●
on Telephones and End User Devices, then scroll down to IP Telephony)
Avaya IP Agent (for additional information, go to http://www.avaya.com/support, click on
●
Call Center/CRM, then scroll down to IP Agent)
Avaya Softconsole (for additional information, go to http://www.avaya.com/support, click
●
on Call Center/CRM, then scroll down to IP Telephony)
The connection for the end-point is supported whether the customer is directly connected using
a network inter-face card (NIC) or the customer has dialed into their network using a dial-up
point-to-point (PPP) account. The connection is managed via a registration session with the
Avaya server. The call server manages the voice connection directly to a circuit-switched
telephone (Telecommuter configuration), directly to an IP Telephone (Control of IP Telephone
configuration), directly to a DCP digital telephone (Control of DCP Telephone configuration), or
over UDP/RTP to the IP Softphone's iClarity IP Audio H.323 audio end-point (Road Warrior or
VoIP configuration).
At any time, an end user can put a softphone into one of the following modes by changing a
software menu:
Road-Warrior (Voice over IP (VoIP))
●
Telecommuter
●
Native H.323 (only available with Avaya IP Softphone R2)
●
Control of IP Telephone (only available with IP Softphone R4 and later)
●
Control of DCP Telephone (only available with IP Softphone R5 and later)
●

Beginning with the November 2003 release of Communication Manager, R1 and
Note:
R2 IP Softphone and IP Agent, which use a dual connect (two extensions)
architecture, are no longer supported. R3 and R4 IP Softphone and IP Agent,
which use a single connect (one extension) architecture, continue to be
supported. This applies to the RoadWarrior and the Telecommuter configurations
for the IP Softphone. Native H.323 registrations for R1 and R2 Softphones
continue to be supported.
