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) ?
