Hi,
I am using six H.460.19 supported terminals registered to my GnuGk-3.8 and call a MCU, the multiplexing works fine(I see the multiplexed audio/video packets go through to 3000 port I set in gatekeeper.ini), just one issue: after about 20 minutes, GnuGk showed the following messages and the video is frozen in terminals, also at this point, terminals cannot connect to MCU again(in wireshark I saw GnuGk responsed releaseCompplete right after terminal's setup message), but all terminals can still register/unregister to my GnuGk-3.8. could you help me take a look at the following deadlock message Thanks!

got it Thanks Jan!Regards, Bo XuHi, RTP multiplexing is a feature that needs H.460.18/.19. When you enable it, endpoints using H.460.19 may use it. Unfortunately not all endpoints support the feature, but the presence of multiplexing support is auto-detected. 3000 and 3001 are the ports used by GnuGk to receive multiplexed RTP. The endpoints that the endpoint are using (through the NAT) are auto-detected. The additional load for GnuGk is minimal.

Thanks!Regards,Bo Xu
