[Serusers] SER not forwarding early media from PSTN Gateway

[Vitaly Nikolaev]

Hi

 

That the idea RTP proxy. rtpproxy should get something from client to know
where to send RTP packets because u can not predict  PORT on client side if
it behind NAT.

 

U have to fix the problem on or GW.. for example on cisco there is command:

 

sip-ua

disable-early-media 180

 

Than not exactly what u describing.. but may be will help.

Kanakatti thanks for your suggestion,  tried it  but did not work for..  I
captured some packets and I notice that my gateway is senting this media
just after sending code 100 trying and does not sent 180/183...

I'm trying to run TCL script on my router that will play the credit amount
to my SIP users.  The debug on my router is showing  that the script is
running fine and I can see the RTP payload between my router and SER but I
dont see the RTP payload leavinf SER to my AU.

 

 

my router just sents code 100 "trying" and then plays the media for the
credit amount... Any idea how to fix this??

 

Thanks

 

Mohamed

Are you sure your 180/183 responses are being forwarded back to the UAC
appropriately (and through MediaProxy)?  
Thats usually where the early media data notifications reside

e.g. make sure that your on_reply_route() section has something like




onreply_route[1] {

  if (!(status=~"183" || status=~"180" || status=~"200")) {
    break;

  };

  fix_contact();
  use_media_proxy();

  break;

}


cheers

When I call to PSTN network from my UA,  The call is forwarded to the PSTN
gateway by SER with is configured with mediaproxy.  Tha gateway normally
sends some early media before the call is connected..  I want SER to relay
this media to the user Agent.   Is there a way to configure SER to forward
this media to UA before is connected..

 

Thanks in advance..

 

mohamed.
