I have set up SIP Line in our CS1000E rel 7.5. and currently have one Avaya B179 Conference phone programmed. I can make calls from the set either to phones on the cs1ke switch or to other switches in our network. My problem is that I can not receive any calls on the B179. When calling it it would appear as though the call is going through, normal ringing. Doing an ENTC in LD 80 for the calling set all appears nornal for the call setup but doesn't seem to go anywhere. I'm guessing that I have missed something but considering the Docs aren't that great I wouldn't be suprised. Anyone have any ideas as to what piece I've missed. We also have System Session Manager in our system and don't have any problems with it or its call routing.
