Hello Rinchen,

The BYE from UA2([email-masked]) to the proxy(192.168.4.171) will be :

BYE sip:192.168.4.171 SIP/2.0
Route:<sip:[email-masked]>
...

And then from the proxy to UA1([email-masked]) :

BYE sip:[email-masked] SIP/2.0
...

Kind regards
 
Jean-François JESTIN

Subject: [Sip] difference between a strict router(2543) and loose router (3261)

Hello folks,

What is the difference between a strict router(2543) and loose router
(3261) ?

Can any body point me to some call flow standards involving a strict
routing proxy
as described below ?

Lets say i have :-

3261                             2543 (or 3261 in strict routing)
3261
UA1---------->Proxy(strict router)---------->UA2
192.168.5.124         192.168.4.171
192.168.5.129
1205481000
1205481001

INVITE arrives at UA2 as :-

INVITE sip:[email-masked] SIP/2.0
Record-Route: <sip:192.168.4.171>

My question is how BYE will be formed by UA2 (or UA1) ?

for UA2 is it :-

BYE sip:[email-masked]  SIP/2.0
Route :<sip:192.168.4.171>

or
BYE sip:192.168.5.124 SIP/2.0
Route :<sip:192.168.4.171>
Route:<sip:[email-masked] >

what is the significance of this kind of BYE with no username in Request
URI ?

Thanks and
