[SIP Beyond VoIP] Conference Screen Sharing/Video - 488 Not Acceptable Here

[Jonathan Steel]

I've just set up a basic install of OpenSIPS and SylkServer and 
everything
is working apart from screen sharing and video in a conference. It works 
OK
one to one (via OpenSIPS not through SylkServer). To confirm, audio and 
IM
work fine in a conference through SylkServer.

Here's an error from the SylkServer that I think is relevant:

https://bpaste.net/show/fdd1233513d9
(488 Not Acceptable Here)

My setup is as follows:

   OpenSIPS + MSRPRelay:
     sip.dev.lan
     10.74.6.250

   SylkServer:
     meet.sip.dev.lan
     10.74.6.251

   Client:
     Blink
     10.74.11.137

Does SylkServer run its own MSRPRelay and does it need to be configured
to use the one on the OpenSIPS server instead? Otherwise what do you
think I'm missing?

Thanks,
