[Asterisk-Dev] Request-URI for SIP BYE method is also WRONG !!!

There is something seriously wrong with SIP implementation in Asterisk.  It seems not to be in compliance with RFC 3261 !!! 

When issuing a BYE request, asterisk sets a WRONG Request-URI after the BYE keyword.

I am enclosing 2 SIP debug listing below to illustrate this problem.

The 1st debug listing comes from Asterisk v1.2.1 answering an incoming SIP call and hanging up,
The 2nd debug listing comes from the X-Pro Softphone doing the same thing.
Compare the Request-URI of the last BYE request.

Also, the same problem with the Request-URI after the REFER method breaks the transfer() functionality, and probably causes multitude of other problems...


Regards,
Daniel Leeds
