Have you reviewed your speed/duplex settings on ALL of the ethernet interfaces involved in this connection? CLAN's, PMI's, LAN switch ports... and such?

Have you traced the call that fails and verified your codecs?

Post a list trace of the stations. look for full packet loss on the trace and check the UDP ports that are being used and make sure they are not blocked in the firewall.

It's most likely a LAN/WAN issue, not all UDP ports are being forwarded, is the most likely cause. Check with the data vendor to make sure all ports in the UDP port range definied in the ip-network-region for BOTH sides are being forwarded over the LAN/WAN.
