one way Voice communication
I have the following setup
CUCM -H323 gateway-h323 gateway-PBX. I can successfully make a call from PBX to CUCM but when I make test calls from CUCM to PBX, although the PBX rings twice, there is no ringback on the IP phone and give busy tone.
on doing debug cch323 all, I get disconnect cause 47. I think all devices have been configured correctly. !'m I missing something?
