UC500 External Inbound Call

Unanswered Question
Jan 5th, 2009


I have recently installed a UC500 for a customer. I am using H323 instead of SIP. When I make an external call outbound, it works fine.

However, when I make an external call inbound, The IP phone rings and when I go to answer it, the call drops at the IP phone end, but the external phone still hears ringback. I am using G711 as my codec. Has anyone seen this problem before?

I have this problem too.

debug voip dialpeer to make sure you're not hitting dial peer 0. If you're hitting dial peer 0, try adding something like this:

dial-peer voice 1 voip

incoming called-number .

dtmf-relay h245-alpha

codec g711ulaw

no vad
