Hi Michael,
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 phone B registers with proxy B using domainB.
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.

Hi all
i know this is a stupid question
but i dont use sip to make a phone call very often ,
i have setup up two opensips server in my intranet environment
i use two phones to register on each server
how to make a phone call from one to another one
do i have to add the the destination domain name behind the alias
number when i dial out ?
or why can i dial the alias number without domain name , then the
opensips server will routing it to a the opensips server automatically
