Summary:                    SIP video phone requires numberofmediastreams > 4
(chan_sip.c)
Description: 
I have a SIP video phone that I need to connect to Asterisk 1.4. The video
phone sends a special invite message. The invite message includes an SDP
part with 4 m blocks (media blocks).

Since asterisk 1.4 can handle a max of 2 m blocks, this requires making a
tiny change on the ./channels/chan_sip.c file. The change will modify the
following line:

if (numberofmediastreams > 2)
to be changed to:
if (numberofmediastreams > 4)

I implemented the change on Asterisk 1.4. It was successful.

I need to know what model the phone is and what the 4 media streams are.  A
SIP trace would be helpful in this regard.
