[Asterisk-Dev] Enum and Registrar

[Jens Kübler]

Hi

I spent some time today getting familiar with the chan_sip.c because I ran 
into a problem with EnumLookup.

I configured enum to return sipextension at asteriskserver. I'm registering my 
clients with asterisk so they are known to the server.

If I dial a number, it will be resolved to sipextension at asteriskserver and the 
Dial process starts. Unfortunately asterisk detects an loop and cancels the 
call. The INVITE uses the sipextension at asteriskserver instead of the 
registered contact info available for that peer thus causing asterisk to call 
itself.

To solve this problem you would need to discover before or within the "DIAL" 
that asterisk itself is responsible. You will need to search for the 
corresponding struct sip_pvt which holds the "Contact" info and substitute 
it.
I think the check for a loop is the last place to substitute the 
sipextension at asterisk as a lot of information has been set up already.

Is anyone aware of this problem or am I missing something here ?
