<div><tt>Hi Michael,<br>
<br>
In SIP, each SIP server does server a certain set of SIP domains
(defined as FQDNs or IPs). Let's assume phone A registers with
proxy A using domainA and </tt><tt><tt>phone B registers with
proxy B using domainB. <br>
To have a call from phone A to phone B, A must dial B@domainB
- so when the call will land on proxy A, proxy A will see
domainB is not locally served and it will forward to proxy B
(responsible for domainB). This is call inter-domain DNS based
routing and it is covered by the OpenSIPS default script.<br>
<br>
</tt>Regards,<br>
