[OpenSIPS-Users] Mediaproxy relay exception for video call

[Carlo Dimaggio]

Hi all,

I have an exception in media-relay when I try to perform a video call  
(h.263/264 or 261). A voice call works fine.
The two endpoints are Ekiga 3.0 and Xmeeting 0.3.4a (or Xlite 3) while  
the other versions are: opensips 1.5.1, media dispatcher and relay  
2.3.4.

Is this problem related to mediaproxy 2.3.4?


Thanks and regards,
Carlo Dimaggio
