I have a bandwidth limitation and need to carry 8 simultaneous calls. Each of the ADSL lines available can carry a maximum of 4 simultanous calls.Any idea how to setup Asterisk so that the IAX2/SIP calls are sent down two seperate network interfaces (connected to ADSL) and thereby allowing agregating the bandwidth. There is only one ip to send the calls to as the Asterisk sends all calls to the central Asterisk server and they are then forwarded from there. I was thinking of setting up two IAX2 trunks with different ports and then natting the IAX2 port on the linux server and forcing the traffic down an ip interface based on the port. Not that I know how to do this.

 However the one problem I have is how to ensure that Asterisk splits the calls over the two IAX trunks?

Any suggestions welcome.
