In this trace I see 2 bugs (b2bua module bugs?) and a possible third bug:


1) The From generated by b2bua is illegal:

 From: <sip:0100000715 at 41.1.1.66>;tag=call-F1030790-3656-2D10-1919-AB at 192.x.x.154c0a8c89a-4f7

The @ symbol in the "tag" is not valid. A @ can be present in a header
param if it's enclosed in double quotes, but "tag" doesn't allow
quotes, it must be just a token.


2) The ftag param in Record-Route is illegal:

Record-Route: <sip:41.x.x.33;lr=on;ftag=call-F1030790-3656-2D10-1919-AB at 192.x.x.154c0a8c89a-4f7;vsf=AAAAAFlyXxh7QkwaAQVydAUfHAADHxsbGAA2>

The @ symbol in a SIP URI param is not valid. Also, a SIP URI param
cannot contain double quotes, but just a token.


3) The 200 replied to the UAC has no mirrored Record-Route, but I
expect that this is exactly the desired behaviour of the b2bua module
:)
