>  Hello,
>  I tried sending this to the video mailing list, but after three failed
> deliveries, I figure that's a dead-end.
>  Our office is setting up a video conferencing system and I've been
> tasked with making it work through FreeSWITCH. The end-point we're using is
> a Cisco Telepresence SX-20 (
> http://www.cisco.com/c/en/us/products/collaboration-endpoints/telepresence-sx20-quick-set/index.html)
> unit.
>  Currently, the test setup looks like this: a laptop running Zoiper, the
> SX-20 and a Debian server running FS, all on a LAN. Both end-points are
> registered on the internal profile. During calls, the audio stream works
> without a hitch, but the video is more problematic. There's basically no
> video. Setting FS to proxy media mode and enabling the proxy codecs lets
> audio pass, but no video at all. Setting FS to bypass mode is only
> marginally better: there's certainly a video stream, but it's corrupted
> beyond usefulness and only works from Zoiper to SX-20.
>  I've run Wireshark and in proxy mode, h.263 packets move only from
> Zoiper to FS with nothing coming from FS to Zoiper; whereas in bypass mode,
> there is a stream of packets going from the SX-20 to Zoiper, but there's no
> image.
