BCM50 Talk Path Issues

[ttscanada]

I have been working on this for several weeks now, read the applicable posts in this forum, reviewed the documentation, and have not been able to resolve this issue.

I have 2 BCM50's tied together with VoIP trunks, each BCM has an i2002 connected to it via VPN.

Calls from an ip phone thru to any local extension or the PSTN on it's home BCM work fine.

Calls from local extensions on BCM A to local extensions on BCM B thru the VoIP trunks work fine

Calls from local extensions from BCM A to BCM B thru the VoIP trunks and then out on the PSTN work fine

Calls from the ip phone on BCM A, to a local ext or the ipphone on BCM B connect but have no talk path.

Calls from local extension on BCM A to ip phone on BCM B connect but have no talk path.

I have opened up ports 28000-28255 and 51000-51200 on the routers at both BCM's, still no talk path.

I have logged onto both ends with monitor and observed the connections, as well as had technicians at both ends to verify results.

Any ideas?

Presuming that the BCM's are tied together with their own VPN tunnel, you need to allow tunnel to tunnel traffic to pass.

i2002 (registered to BCM A) voice packets coming in a VPN tunnel will be blocked from travelling across the branch tunnel to the other BCM and also to i2002 coming in another tunnel registered to BCM B.

Both sites need tunnel to tunnel traffic allowed and may also need to have the subnets of the i2002s added as remote networks.
