Hi, we are implementing a CME, and we are making some tests and all is working fine except one thing. When a sip phone registered to cme make a call to a remote site (the communication between the remote site is h323), the call is established without problems, but if you add a phone from pstn to a conference, the sip phone registered to cme and the pstn phone have audio between them, but the phone from the remote site does not. He cant hear us and we cant hear him. The conference remains established between three phones, but the remote site have no audio at all.
Maybe the "media flow-through" command into the voice service voip configuration can help. What do you think?
Solved! Go to Solution.
The conference bridge is the local CME, and there is no problem when we make a call to the remote site. So the remote phone system (it is a PBX) should be reacheable and be able to reach the local CME (I think). Another thing that we are seeing is that when the local phone put the remote phone on hold, the remote phone does not hear the MoH, but when the local phone exit the hold, there is audio again. The MoH server is the local CME also. Thank you!!
