OmniTouch UC R3.0 – Troubleshooting Guide for IP Softphone

Edition 3 – Page 9

Details for modules and protocols used are as follows (example with IP Web Softphone):

IP module of Softphone applications is composed of:

• GAELIC: Generic ATAPI Evolutive LIght Client, an executive binary dedicated to the VoIP

processing. Used by IP Web Softphone only.

• ATAPI-light: a proprietary protocol (Alcatel Telephony API-light) dedicated to VoIP

messages towards the Open Telephony Server (OTS). Used by IP Web Softphone only

(versus “full” ATAPI used by 4980 Softphone applications).

• DLL_UA: a binary dedicated to UA messages for VoIP signaling.

• ABERS: an executive binary dedicated to voice processing, which performs voice packets

management, audio sampling and coding management.

• Microsoft Audio API: an API that gives access to the soundcard or USB audio device

services.

• Sound_PC (Sound card): a DLL for the audio media management. This binary provides

the control of the line level signal of microphones and speakers, as well as an audio tune

Wizard to calibrate the line level of microphones and speakers for the best audio quality.

Note:

the ringing signal is generated locally on the client machine either through a wave file

or a beep system. The callback tone and intrusion beep are also generated locally.
