Dennis, I removed your pcap since you didn't want it exposed. Please don't upload anything you don't want on here. There is always the chance it is cached somewhere else.

Can you please provide your sip.conf, sanitized? I'd like to see if I can reproduce the issue with another softphone and your sip.conf settings to see if it's related to X-lite's specific requests or just your particular configuration.

> I tried to use X-Lite 3.0 and before any RTP packets went through, X-Lite would send a Bye.  X-Lite was logging "ParseException dereferenced ParseBuffer eof" in its debug log.
> I tracked it down to the SDP message Asterisk sends for the OK after the INVITE doesn't end with a CRLF.  RFC4566 says "The sequence CRLF (0x0d0a) is used to end a record," so I guess that means the last record should have a CRLF.
> It's exceptionally rare I would use X-Lite 3.0, so this problem may exist in all of v11, but the issue intrigued me enough to track this down.
> I've attached a patch against 11.2.0-rc1, but this most likely isn't the best fix (just tacking a CRLF to the end).  It did prove out that adding a CRLF to the end of the SDP message allows the old X-Lite 3.0 to work with Asterisk 11.2.0-rc1.  11.1.0 has the same problem, although I did not try the patch with it.
