asterisk users - Nov 2007 - IAX complaints? What are they?

Hi,

We all know what the principal advantage of IAX is, doing it all on a
single port, right? But now and again I hear complaints about it. What
specific griefs have you had with IAX and has it stopped you from
using it entirely? Under what conditions have you had problems?

I have used SIP and IAX for about three years now. We don't do a lot
of traffic, but I haven't really seen a difference in quality or
dropped calls.

What have others on the list experienced?

With SIP you can "attach" custom variables to calls (using
X-... headers).
IAX (Inter-Asterisk eXchange!) can't do that (yet).

I am not sure why, what versions, under what conditions, but audio 
cutting out has been seen many times.  Simply switching to SIP has 
solved these issues.  I think trunking (one of the main selling points 
of IAX due to less overhead) may be a common denominator.

Thanks,

Griefs?

rejected connect attempt from 111.111.111.111, who was trying to reach
'12345678' No authority found
call rejected by 111.111.111.111: No authority found

But once it works it works...

I have DTMF issues with sending calls from 1.2 to what I suspect is a
really old 1.4 build via IAX that then hands those calls off as SIP .
But I suspect it could be fixed in the SIP configuration. This is a
very isolated situation.

Sorry for jumping in, but besides ZoIPer/Idefisk, are there
IAX-capable softphones for Windows?

Thanks.
