[cisco-voip] Silence with Nortel integration

[Jason Aarons (US)]

I'd get a sniffer up on 3845s Ethernet port and watch the H225/H245 packets.  Got another H323 endpoint you could test with to narrow down it's a Nortel issue?

I have a 3845 configured as an h.323 gateway. I have four PRI’s connected to this gateway from the PSTN. I also have a single PRI connected to this same gateway used as a tie line to a Nortel system. I have had no complaints on calls going or coming from the PSTN. I have had several complaints on calls to and from the Nortel box. The call could be setup fine and you are talking but the call basically goes silent for about 10 – 15 seconds. The call does not drop only silence. Also if you stay on the call the audio starts up again. I don’t think it is an IP routing issue because calls to the PSTN work correctly and calls do work to the Nortel it just will stop for a few seconds. There are no slips and no errors on the line.
