Hi,
Here is the sip trace for the calls, it strange as all other phone work
except X-Lite, it appears that sound is not getting from the softphone to
the server. Though if the softphone talks directly to asterisk it works ok.
This is the case if MediaProxy is used or not.
There is a lack of codecs in the invite which is strange as I have 4
enabled on the server and the softphone.
Seems you don't look on the wright place .. because your X-Lite is offering
PCMU ... just look at the m= line on the first invite.

Umm ... umm ... by ROUTER IP ADDRESS do you mean your public IP on your NAT
router ? ...
does your router have SIP-ALG activated ?, that could explain the problem.
This INVITE is the one that just arrive at your proxy? ... if so .. your NAT
router is doing sip-alg .. so mangling all the SIP dialog, and they usually
does a very bad job with that.
