OmniTouch UC R3.0 – Troubleshooting Guide for IP Softphone

Edition 3 – Page 7

1.2 Architectures

1.2.1 Two kinds of client

We can distinguish here two kinds of client stations according to the protocol used:

• UA (Alcatel proprietary protocol) client:

 IP 4980 Softphone

 IP Web Softphone

• H323 client:

 4980 Softphone in Nomadic VoIP mode

" Above clients are only available on Microsoft Windows stations

as the IP module for the

Web Softphone application is designed for Windows only (and therefore cannot be used on

other operating systems).

UA clients H323 clients

IP 4980 Softphone

IP Web Softphone

4980 Softphone in

Nomadic VoIP mode

IP 4980 Softphone and IP Web Softphone

These clients are named “IP Softphone” and users are declared as “Multi-Media PC2” on OmniPCX

side. The signalization used is the proprietary UA (Universal Alcatel) protocol, like for IP Phone sets.

These clients use the RTP ABERS stack (ABERS stands for “Alcatel Brest Evolutive RTP Stack”).

" Refer to the section 1.2.2 for architecture aspects.

4980 Softphone in Nomadic VoIP mode

This client is also named 4980 Nomadic VoIP and needs to declare:

• A virtual phone set on OmniPCX side (Ghost Z with Nomadic feature).

• An IP trunk on OmniPCX side.

• A Nomadic gateway on OmniTouch UC side.

This kind of client uses the standardized H323 protocol, and like IP Softphone, it uses the RTP

ABERS stack.
