Hello Users..... I'm in Dilemma with the performance on SIP and IAX....
Can any one help ...
1) Difference between the SIP and IAX... which one is Best... in VOIP service
I'm using only SIP protocol for my VOIP in OpenSER... And Also I using Asterisk in SIP....
we can Communicate the SIP and IAX by below scenario
SIP (UA) --------> OPENSER -----> ASTERISK --------> IAX (UA)....... this I can do... IAX -----------> OPENSER -----> ASTERISK ---------> SIP/IAX. But main problem is ... Suppose IAX ------> ASTERISK-----------> openSER ------------> SIP / IAX ... How ?
Help me this.... forgive me in English.... :P

I don't think this one would work. It would need to be: IAX -------> Asterisk -------> OpenSER ------> Asterisk -------> IAX
But main problem is ... Suppose IAX ------> ASTERISK-----------> openSER ------------> SIP / IAX ... How ?
This one would be just like the one above: IAX -------> Asterisk -------> OpenSER ------> Asterisk -------> IAX
Help me this.... forgive me in English.... :P
I would recommend you to use SIP, because I think Asterisk is the only server that supports IAX, and almost all phones are SIP phones, not IAX phones. I believe IAX is mostly designed to connect two Asterisk servers.

Indeed, IAX means Inter Asterisk Exchange. It came up with Asterisk.

As they all said above.
I think IAX is supported on some Cisco equipment for WAN connectivity, making it useful for interconnecting back-end systems and servers (e.g. server to server rather than server to UA).
I believe IAX uses the same port(s) for signalling as for media, as compared to SIP vs RTP using separate streams. This makes it easier when doing port-forwarding and may give it an advantage for NAT traversal.
That being said, it is not yet an officially recognised protocol (from what I heard) and has not yet been as widely adopted as SIP. In short, you will find more SIP-enabled devices than you will find IAX devices, though there are some IAX softphones around.

IAX is definitely not supported by Cisco. Perhaps you were thinking of some other protocol?
You are correct, IAX uses the same ports for signaling and media.
