We have strange situation, may be someone have idea.
Two nodes (branch offices in two countries), common hardware, internode link - Hybrid, IP, calls via VPN overflow (H323), DPNSS prefixes created, used G711 (IP domain, VPN overflow).
Node 1 - R11.0.1 k1.520.36
Node 2 - R11.2 l1.301.35
IP user from node 2 calls IP user from node 1.
t3 trace show standard behaviour - SETUP to GA from node 1, RTP info (IP user node 2 address), after CONNECT/CONNECT ACK - we have FACILITY - info about RTP ports/addresses (IP phones from both sides).
Connection established, no problem with voice.
User from node 2 want to make conference and start to dial number. In t3 trace we see FACILITY message (info about GD-3 RTP port/address). User from node 1 shall be putted on hold and hear "music on hold" from GD-3. But hear silence.
After some timeout connection broken (RELEASE - TEMPORARY FAILURE).
And on node 2 we have incident - 0:4412=H323 : end of the communication with cause 5
We have some more network nodes (R10.1.1, R11.0.1) with the same type of connection (from PBX point of view, from data network point of view - IPsec). No problem with calls, hold, conferences.
Maybe someone have the same problem with R11.2 in full IP ABC-F network (with hold, conference in network).
Problem with RTP between nodes
Re: Problem with RTP between nodes
Hi Vad,
I know this incident. Some old versión have the parameter "direct rtp for H323 Terminals". Must to be equal in both nodes.
I hope help you.

may the force be with you....
Re: Problem with RTP between nodes
direct rtp for H323 Terminals = False on both side.
With sniffer - we see - RTP present (music on hold) on the remote side.
We have no problem with usual call. Problem started when user placed on hold (IP user now shall receive RTP not from initial calling set but from GD)

Re: Problem with RTP between nodes
In 11.2 we have faced also weird IP problems, not with H323 but SIP. We did downgrade and works fine...ALE was checking. We have had like 3 incidents already, therefore we decided to wait a little bit more before trying again.
