Hello i have the following problem :

I create a conference in MCU 4501 and call the endpoints 3x E20 .Two of the E20 are with private ips 192.168.x.x and one is with public 213.147.x.x The conference starts but the public E20 doesn't sends video and audio and after a short period of time it comes out of the conference. There is the log from the MCU :


Disconnect reason "timeout"; Time in conference 8 mins 24 sec; Participant joined by invitation; Protocol "SIP"; Media encryption status "unencrypted"

Endpoint: IP address "192.168.1.248"; DN "sip:[email protected]"; H.323 alias "naruto"

Media from endpoint:Bandwidth 832 kbit/s; Audio codec "AAC"; Video codec "H.264"; Video resolution "352 x 288"

Media to endpoint:Bandwidth 768 kbit/s; Audio codec "AAC"; Video codec "H.264"; Video resolution "352 x 288"


Can you please help.Thanks

Hi Svetoslav


As Jens Didriksen said in neighboring topic, you need VCS Expressway or VCS Starterpack for your external E20(213.47.x.x.)

VideoFirewallOption also help you, but recomend decision to use VCS Expressway.
