[Freeswitch-users] multiple internal ip

Hi, I would like to have more internal IP addresses to do some "Multiple Companies". The WAN IP is used (80.X.X.125) to mount all trunk (1 trunk by company) to the same provider sip. Is it possible to have an internal IP for each company: company-a.org => 192.168.1.1 company-b.org => 192.168.1.2 company-c.org => 192.168.1.3 company-X.org => 192.168.1.X How to use FreeSwitch this way? Thanks
