           Summary: Video calls fail using SIP protocol with
                    telepathy-sofiasip
           Product: Telepathy
           Version: 0.6
          Platform: x86 (IA32)
        OS/Version: Linux (All)
            Status: NEW
          Severity: normal
          Priority: medium
         Component: sofiasip
        AssignedTo: mikhail.zabaluev at nokia.com
        ReportedBy: chris at cvine.freeserve.co.uk
         QAContact: telepathy-bugs at lists.freedesktop.org


Video chat works fine for me using telepathy with the the XMPP protocol (say,
via the google servers) using the empathy client with telepathy-gabble, both
with empathy to empathy, and empathy to google talk browser plugin.

However, although audio chat works between SIP accounts using empathy with
telepathy-sofiasip, if video chat is chosen, the calling client appears to
close the connection as soon as the connection is made.  I have tested on two
different sip accounts using empathy to empathy, and empathy to linphone. 
Video on these sip accounts is supported and works fine if the connection is
made with linphone as the client at both ends.

If an audio connection is first made (successfully) between SIP accounts using
empathy, and then video chat is chosen subsequently on the open connection, the
same thing happens: the calling client appears to close the connection as soon
as a video connection is made.

Both machines have the following installed:

empathy 2.30.2 with gnome-2.30.2
farsight2-0.0.21
libnice-0.0.13
sofia-sip-1.12.10
telepathy-python-0.15.18
pycrypto-2.1.0
pyOpenSSL-0.10
telepathy-glib-0.10.7
telepathy-farsight-0.0.14
telepathy-mission-control-5.4.3
telepathy-gabble-0.8.14
telepathy-sofiasip-0.6.3

I attach separately the empathy debug logs of a video chat attempt both from
the caller and recipient, both using telepathy-sofiasip.
