[OpenSIPS-Users] Lookup location problem on OpenSIPS(multi-domain) + Asterisks

Hi Kook,

If you want to use multiple domains, then the domain info must be 
consistent between registration and lookup - I mean users should 
register and be searched inside the same domain (for each user).

What domain do users A and B use for registering into OpenSIPS ? Also 
what is the domain in RURI when looking up for user B in OpenSIPS (for 
the call received from Asterisk) ?

Regards,
