asterisk users - Dec 2011 - Use different local IP for each SIP trunk

Hello,

I have a SIP provider whom I may want to have multiple trunks with, rather than
just adding more channels to the individual trunk. I have discussed the matter
with them & they have told me that the only way that they identify which
trunk should be used for each call is simply by the source IP address that the
SIP calls are originating from. They do not use sip username/password or any
other means to authenticate the remote caller.

With that said, then it appears that the only way that I can have multiple
trunks setup with them is to have asterisk use a different IP for all of the SIP
& RTP traffic for each given trunk. Essentially I would setup multiple IP
addresses on my eth0 interface. Is there a way in asterisk that I could
configure it to use one local IP for the source in all SIP/RTP traffic for 1 SIP
trunk & then a different local IP for the other SIP trunk?

Thanks,
-

AFAIK you can add exterin= in sip.conf for each trunk, correct me if i'm
wrong.

I think this can be used only in [general] section not on peers 
definition; also useful only when asterisk is behind nat. Not?

Externip support per device in sip.conf
