When I lost a week of my life to trying to connect multiple Elastix (Asterisk-based) boxes with Cisco 7960s while traversing multiple NATs and dealing with a few Sonicwalls– I decided that it was time to learn something about IAX2.

I have one thought: “Why the heck did I ever waste time on SIP?!?!?!”

IAX2 phones are a BREEZE to set up. They could care less about NATs other than making sure the port forwarding for its SINGLE port is working.

IAX2 trunks between Asterisk boxes were a little trickier, but once I got it working, it works like a champ!

No more sip_nat.conf for me! Woohoo!

I am disappointed to see so few IAX2 phones out there, but I’m sure we’ll be pushing them for our clients– and we’ll be proud to but them from VoipSupply.

Whenever you think of VoIP. the first name comes is SIP. When you feel SIP is not giving you the proper voice data on any given condition, then IAX can give you the proper solution and best voice quality. There are proof of this above statements

Anyone know why the IAX protocol in this phone was not given a line appearance button? Or did I set something up incorrectly?

IAX is much easier to configure to go through NAT, and as such these IAX phones are ideal for telecommuters who need to link up to the main office. We only need open the 4569 port to the server and don’t have to worry about all of the additional ports that SIP requires.

Actually I just took a look at the instruction manual for this phone at
http://www.citel.com/Products/ip-phones/ci4110_manual.pdf

This phone apears to be made by ATCOM since the firmware is virtually identical in terms of user interface. I hope they fixed some of ATCOM’s bugs before making this version. VOIP supply please contact me if you want to know some of my ATCOM issues.

As Apple says, “It just works”. SIP is a nightmare in the real world. I have been using cheap Asian IAX2 phones for some time, I am sick of pleading with Polycom to make a decent phone with IAX2!

I use IAX because it is easy to configure. It needs onlyt one port and works thru my corporate firewall with worrying about rtp and all the other nasty setting that go along with it. We use IAX2 to communicate with several telecommuters around the country.

IAX2 rules!!

I use IAX because it goes through NAT. Prior to IAX, session border controllers were an option. Do you know how much SBCs cost?!?

I have great hope for the Citel 4110 for teleworkers. Selling SBCs to avoid the horrors of SIP over NAT’d networks is not easy.

I have always found it ironic that SIP (from the INTERNET Engineering Task Force) has more difficulty with NAT than H.323 (from the International TELECOMMUNICATION Union); it would seem that INTERNET people should get NAT (and networking in general) better than TELECOMMUNICATION people.

I’ve used IAX2 for four reasons:

1. Because it leaps tall firewalls & NAT routers in a single port.

2. Because is conserves bandwidth when trunking between servers.

3. Because it support encryption with minimal setup headache.

4. Finally, we use it because it’s different, and so not so likely to be the target of some kind of malicious attack.
