I am facing strange behavior and want to understand root cause of this.
interasite call should be G.711 and intersite should be G.729.. configured appropriate region and applied on respected trunk and every thing is working perfectly.
1 ) HQ Site
have software conference bridge
and hardware transcoder in HQ router register to HQ CUCM.
2) BR1 Site
the problem is that when I am applying MRGL with hardware transcoder and software conference in HQ device pool then conference between HQ & BR is working perfectly when invoked by HQ Site.. and it is not working when I applied it on the HQ phone level MRGL..
Finally I manage to resolve the issue as per requirement.
In order to achieve this..
Software conference bridge/Media Resource must have the same device pool as of Transcoder then only , software conference (S/W MRGL) can invoked trascoder which is sitting on different Media resource group list at phone level.
