Summary:                    Video RTP is not sended to originating SIP extension
when using IAX2 to interconnect both servers
Description: 
When i use IAX2 to interconnect two servers, Asterisk does not send RTP in
H.263,263+ or H.264 to the originating SIP extension of the call.

It´s always reproducible and it always happens in originating extension.
Other party could see you but you could not see him/her.

Analyzing RTP/SIP captures, i see Asterisk1 (from where i originate SIP
Video Call) does not receive RTP packets in video códec sended by client
SIP2 in other Asterisk2

It does not depend on Softhphone or Hardphone used. We had same problem
with Grandstream GXV3000, or instead Eyebeam Softphone.

I met the same problem with asterisk 1.4.17 !
When I use ami command "originate" to create a call like this:
  Action: Originate
  Channel: SIP/301
  Exten: 303
  Callerid: 301
  Context: from-sip
  Priority: 1

extensions.conf:

  exten => _30X,1,Dial(SIP/${EXTEN})

301 can see the video from 303,but 303 can not see the video from 301.
If 301 dial 303 directly ,the video works fine.
