This has nothing to do with stateless or not. A username only has
significance in the domain defined in the host part of the request URI. The
user gautham is not known in 10.10.10.8, but they are in 20.20.20.8.
Therefore, the only request URI that ever makes sense is [EMAIL PROTECTED],
and this is true for stateful, stateless, forking, or whatever.

Lets not confuse the issue. There are several ways to handle firewall
traversal, and they are all hacks. What you are describing is not normal
behavior and not specified in rfc2543. Whether its right or wrong for
firewall traversal is a separate issue.

Same as above. This is not rfc2543 behavior.

Hi All
I have a scenario which I am not very clear about.
Lets say I am inside a Lan and my registration with my SIP proxy is
HRISHKESH and the Sip proxy in my Lan IP is 10.10.10.8, If I want to send a
INVITE message to someone who is outside his lan, and whose registration
with his proxy is GAUTHAM and his SIP proxy is 20.20.20.30, what will be
the request URI when I send it the message to my SIP proxy. Will request
line be
INVITE [EMAIL PROTECTED] SIP/2.0 and gautham has to have a registry in my
SIP proxy
or the request line will be
INVITE [EMAIL PROTECTED] SIP/2.0 but the message will be sent to My
proxy whose IP is 10.10.10.8.
Regards
Thanks in Advance
