[asterisk-users] Multi-homed SIP in Asterisk 11?

[Eric Wieling]

This is the standard way we set up our servers.   There is nothing special about it.   Just make sure you disable direct media.

Subject: [asterisk-users] Multi-homed SIP in Asterisk 11?

Most of my experience until recently has been in Asterisk 1.2, and I am just starting to make use of Asterisk 11 for new systems.

I have a question about using SIP on a multi-homed machine.

I have a customer who wants an Asterisk box with two network interfaces:
one on the public Internet (no NAT), and one on a private LAN. The box will not do any IP forwarding between interfaces. They want to connect to a SIP trunk from an ITSP via the public interface, and to have SIP phones on their LAN registered via the private interface.

I haven't tried such a setup before, so before creating a test system, I wondered if anyone here has made such a setup, and whether there are any issues with getting SDP contents and media routing correct?

Cheers
Tony
