1- No changes to device names. eth0 is the main link to the network,
eth1 (also internal) goes to a SIP provider and eth2 (the USB adapter)
goes to another SIP provider. 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.
