All IAX trunks use eth0 2- ifconfig gives the proper IP and netmask for all interfaces 3- We do not specify bindaddr or bindport in the config file as the default is to bind to 0.0.0.0 4- We had to make new SIP trunks to replace the IAX2 trunks to all servers. The SIP trunk is working with no problems. Except for two SIP links to PSTN all internal extensions use the same network interface. -- Telecomunicaciones Abiertas de M?xico S.A. de C.V.

I hope someone else comes into this thread with a helpful suggestion. Antony. -- The first fifty percent of an engineering project takes ninety percent of the time, and the remaining fifty percent takes another ninety percent of the time. Please reply to the list; please *don't* CC me.
Can it happen that the routes lead the traffic through another interface? Did you try a packet capture with tcpdump? Do the packets really leave the usb adapter? Can asymmetric routing be in effect? Maybe there were some static routes that disappeared when the adapter was unplugged...
