Multiple externIP Configuration

Hi,

Im wondering if it is possible to configure external IP addresses in a per connection fashion. The problem is that I have a single asterisk machine to connect two other companies in two separated wan links (each wan with a different external address). And it happens that both clients already have a VoIP network that overlaps mine.

This is not supported in chan_sip at all, and is only available in chan_pjsip if you have different transports bound on different addresses.
