I didn't want to post this because its kind of ugly, but we *did*
actually do it a number of years ago to get around this issue with chan_sip.
Our original architecture was based on LXC, and we had large servers
running hundreds of containers, each running asterisk. The "host" ran
asterisk too, as the gateway for all the container instances.
We once used two of those containers to run asterisk on specific host
interfaces (one instance bridged to one nic, the other to the other).
The host asterisk would route calls out one container or the other, with
the effect you are looking for...
Cheers,
