Summary:                    Video RTP is not sended to originating SIP extension
when using IAX2 to interconnect both servers
Description: 
I discovered now the issue 0012902 but it has been declared closed and I
can not add comments on it.
I am having the same problem described in issue 0012902 on asterisk
1.4.33

Scenario:
SIP(301)---*1---IAX(Head)---------*2---IAX(Branch)---SIP(401)

301 exec a video call passing through the IAX trunk to 401. Only 401 sees
301 video. Video RTP packets are sent by 401 but not get from Asterisk 2.
Same things happen is the caller is 401.
videosupport=yes configured on both sip and iax.
Details on SIP and IAX configuration reported below.

The attached file 20100818 contains a two pcap file showing an incoming
call (receives the video) and an outgoing call (does not receive the video)
from SIP extension 301.

On the asteriks receiving the call (i.e. Asterisk 2) you can see that it
is not processing any video RTP from the phone 401. The "Got  RTP packet"
are only related to the voice packet (Type 08)
