I’m trying to do VoIP with an Avaya system connected to a Nortel via the ITG card in the Nortel. I have an Option61C that I’m trying to connect to an Avaya system and I can not get the D-Channels to talk to each other. I have the Option 61 set up with Qsig but not knowing anything about Avaya I don’t know what to ask the Avaya Tech. The system at the far end is an Avaya S8710 RLS 3.0 (CM 3). Can anyone here help?
