As I understand it the main advantege IAX has over SIP is the number of port it uses and therefore its ability to traverse router/switches and firewalls Also the higher number of simulatanious SIP calls travelling through these devices adds a higher overhead than IAX with it's single port. Personally I like IAX but I there simply isnt enough hardware out there to use it exclusively.
