2 ADSL lines - 1 for incoming calls, 1 for outgoing calls - possible?


Haven’t been able to find a post that conclusively answers this question, however, if there is one my apologies for not finding it.

I would like to know if there is a way to use 2 ADSL lines and tell the PBX to use one for incoming calls and one for outgoing calls. Using 2 NIC’s would be a start, however, there doesn’t appear to be a way to set a trunk to use a specific NIC.

Anyone know of a solution or indeed if it is possible at all?

Kind regards


If you know the IP addresses of your providers server you can redirect outbound calls to the second DLS gateway with a static route in Linux.

Fantastic, so it is possible. Getting the IP address wont be a problem, nor will setting the static route.

What I’m unsure of is where I would tell asterisk what route to use and the syntax. Is this something you know about?
