Both of them are correct. In the first ACK the user agent correctly
recognized that the next proxy server is loose router and put the
Contact from 200 OK into the Request-URI of ACK.
In the other example, the user agent did not recognized that the proxy
is loose router (or does not implement loose routing) and behaves a
specificied in RFC2543, it puts the content of the Route header field
into the Request-URI and the Contact from 200 OK is put into another
Route header field.
Both cases should work.

HI,
I have an interconexion with a proxy-server registrar IPTEL to a Cisco
GATEWAY AS5300 for the PSTN.
When I make a call by a Cisco IP phone, I have no problem but when I make a
call with a call-box(Same as Cisco ATA) or a softphone Xpro (XTEN), I can
speak 20 s and after the call is cut.
I have analysed this problem, the problem is after the SIP ringing frame,
the softphone send a SIP frame ACK with a bad request-line.
IP ADDRESS 80.118.128.1 : CISCO AS5300 GATEWAY
IP ADDRESS 80.118.128.5 : SERVER IPTEL
The RED parameter in the first DEBUG is BAD, he as to be as the same of the
second debug.
That's my debug of the SOFT PHONE: BAD ACKNOWLEDGE
