Hello, you have to look at the sip traffic and see if there is something wrong -- one way is with ngrep:
ngrep -d any -qt -W byline "sip" port 5060 Kamailio itself has nothing to do with media stream (the fax content), unless you do rtprelay via rtpengine/rtpproxy. If you have clients behind NAT, then you have to do rtp relaying. Cheers, Daniel On 03/06/16 10:45, Mx R wrote: > Hi there, > > We use kamailio 4.3.3. And we have one problem with the fax.
