I'm experiencing some very strange stuff. So I've setup a little local phone system involving two Polycom 650's, a laptop as the server and X-Lite to show the problem.
HYPOTHESIS: There is something wrong with the Media Server
Windows firewall is turned off. Everybody is plugged into a D-Link DGL-4300 I’m not sure about the UDP and TCP packet blocking settings.
Problem Scenario 1:
Extension 101 calls extension 102 -- both extensions are marked as "external" and "bind to media server" is OFF.

102 puts call on hold
102 take call off hold
102 puts call on hold -- but it won't work. It doesn't put the call on hold
I keep pushing hold and it doesn't do anything.
Also, while on hold, I do not hear the music. Also, extension 101 does not properly report that it is on hold
102 ends call, but 101 still think's the call is connected.
After 20 seconds, 101 finally ends the call itself.

Also, while on hold, I DO hear the music.
Extension 201 DOES properly report that it is on hold
102 ends call
201 ends call normally
When I reverse things – I hear no music from extension 102.
Clearly there is something wrong with the Media Server. What am I doing wrong?
