[Freeswitch-users] More than one profile

Hello In the wiki, it is suggested that more than one profile should be used if libsofia is the bottleneck. When using multiple profiles to handle incoming call and each profile having an unique port, what is the best way to redirect and distribute incoming traffic? Is there any mod in Freeswitch that can do that? For instance, I may have internal1( port 5070) and internal2 (port 5080). External incoming traffic hitting 5060 will need to be distributed to one of the two profiles. How should that be done? Regards, Woody
