The End of IAX2
Nov 13, 2011
Yesterday Tang Li fixed an IAX2 outgoing voice bug when used as callee. This bug was the result of 1.57 changes back in 4 and a half years ago. An user added remote ring back tone for IAX2 and we merged the source code changes without careful test.
It is surprising this obvious bug was not found until recently reported by another user. Considering that our website has very steady visitors about 1k per month, and over half of them are looking for PA1688 software update, the only explanation would be that nobody is interested in IAX2 any more.
We were proudly to support 7 different communication protocols in PA1688, but wisely reduced to SIP and IAX2 only with AR1688. As video and voice over IP market getting mature today, now I believe SIP will be the only one we need to support with the coming PA6488 solution.

Thank you for fixing this; I had been noticing it over the past couple of years but haven't used VoIP enough to try to track down the problem and I assumed it was a configuration issue. I appreciate that you are still fixing bugs as so many companies seem to abandon their products as quickly as they can. -Matt

Actually, it isn't because of a lack of need for IAX2 support. We have several gateways and phones based on the PA1688 chipset, in fact we tested multiple manufacturer's phones. We configured these to use IAX, and they have never worked without terrible garbling and dropouts across multiple asterisk switches, across many different network scenarios, and were basically unusable. So we moved to using Asterisk IAXY's and analog phone sets.

I came here as a last ditch effort before finally throwing the units out to see if any new firmware had arrived that would make them work.

I would carefully consider continuing to support IAX due to SIP's NAT limitations. I would guess that the lack of interest hasn't been that IAX is dead, rather, that the PA1688 implementation just hasn't worked and people have moved on to other IAX solutions.

Just my perspective, not necessarily that of the rest of the population...

IAX2 has no limitations like sip protocol. i have a company and we have only iax2 devices.

Only have iax2 devices may hurt your company.
