[Asterisk-Users] Sip relay with asterisk

[E. Versaevel]

I've got the following setup:

SIP Client --> SER --> Asterisk --> Iptel.org SIP account

I'm now trying to place an outgoing call, which has to be authenticated at
the iptel.org proxy server (which ser can't do) but I seem to be getting 407
packets with the IP of the asterisk machine as realm.


SIP Client                    SER              *                 Iptel.org
 Invite ------->
                               Invite ----->
                                                Invite ------->

                                                <--- 407 realm ip_of_*

Afaik the realm iptel.org should provide to * should be "iptel.org" instead
of the IP of the * box (which would indicate an error at iptel?)

What I'm trying to archive is that the * box authenticated the calls to
iptel and then leave the call alone (so I will have to find out how to get *
out of the media path)
I'm still new to all this, but I think this could work.

Kind regards,

E. Versaevel
