Hi Marian,
thanks for your help.
this are mostly UAC features. SER is mainly a PROXY and ,AFAIK, there are no such features.
I have read the documentation for UAC under this link: http://www.voice-system.ro/docs/uac/index.html I could not find anything which could help me. Is UAC a Interface for another software/module or something like that. Do I need another software in order to provide isdn features ?
Thanks in advance, Ahmad
