I have Pub and 4 subscribers 2 for each site. when making adhoc conference from anysite using MRGL X with Avaya PBX conference works but if i used MRGL Y conference connected but silent
MRGL X: contains 2 software CFB, MTP (subscribers of site X)
MRGL Y: contains 2 software CFB, MTP (subscribers of site Y)
IP Voice media streaming is activated on all subscribers
Is there routing from endpoints to all CFBs?
Have you made sure that the codecs used are supported by your CFBs?
You can try bouncing the CFB and see if that makes a difference, otherwise, you'd need to take a look at some traces to find out what might be causing this.
