When the call is made from any of the IP Phones, registered on the CUCM, the call succeed. But, when I do a call from Analog phone I experience one-way audio so the calling party does not hear anything. I've checked the routing, H323 gateway bind-scr interface is pingable by the MGCP gateway and CUCM. What could be the issue?
In my experience, network miss routing causing most of the one way audio issue. Are you able to ping the CUCM and MGCP from H323 gateway?. IP 10.200.200.20 is in remote IP of show rtp connection output which device IP it is?. Check the voice codec config in dial-peer and voice-port config of H323 gateway.
