[Asterisk-Users] Sipura SIP vs. IAX

[Adam Hart]

you mean IAX isn't a standard :) Also IAX requires your call router / 
billing gateway to handle the voice traffic too (or you put your CDR 
recording at the end points) With SIP, just the signaling is needed, 
allowing more scalability. I recall talking about this at astericon but 
it never eventuated to anything. The idea was basically keeping the 
original channel open even on a native transfer.
