I have CallManager connected to a gateway at one site. On the other site I have CME. When I do a call from an IP Phone on the CM to an IP Phone on CME, the call rings out at the other side. But when it answers and the phone displaye connected. The IP Phone on the CM still ring out and not get connected.
Calls from CME to CM works well when it is answered.
It seems to me a signaling problem, but I could not solve.
Sounds like a registration issue. Is the CME registered as a H323 Gateway to the CUCM? Is it SIP? Check source interfaces and source IP addresses to make sure everything is registering with the correct CME IP address.
CME is not registered to CM. CM is using local GW which is configured as H323 GW for outgoing calls. On the local GW two VOIP dial-peers are configured. On pointing to CM and other pointing to CME. Allow connection H323 to H323 is configured. CME has VOIP dial-peer pointing to the GW at CM side.
When I configure CME as H323 GW on CM it works well. The problem is when using the GW in the middel.
