asterisk users - Jul 2005 - Unable to call certain 800 numbers through Teliax

We are unable to call certain 800 numbers through Teliax but I thought I
would post this here and see if anyone else had the same problem with either
Teliax or other carriers.

The 800 numbers causing problems pick-up the call right away and are in the
US - American Airlines (8004337300) and Staples (800-378-2753) - we can call
many other 800 numbers just fine. 

Our asterisk setup has a 4-port digium analog card as well as a Teliax
account, currently connected via IAX2. We are able to call the 800-numbers
above through the digium card but not through Teliax. We have also tried
calling the numbers with Asterisk and SIP through Teliax with no-luck
either. We have also tried using several IAX soft-phones (using iaxComm)
directly with Teliax account (no Asterisk) and have the same problem. 

The *only* way that we have been able to call these numbers through Teliax
is to directly X-Lite directly connected to Teliax through SIP - so Teliax
claims that it is not a problem with their service, but with Asterisk.

In examining the asterisk log output it appears that the channel is never
answered and continues to ring indefinately. My guess is that there is a
timing issue with the signals being sent and recieved by Asterisk and Teliax
and that the "answered" is probably being transmitted before the
"ringing"
signal and is therefore being ignored by asterisk and iaxComm. 

If anyone could give this a shot and see what works or doesn't work that
would be great. 

We have reproduced this with Asterisk 1.0.7 and 1.0.9. 

Thanks, 

Cullin

My users have reported the same problem with AA, we also use Teliax. I 
coul care less about Staples but American Airlines is the airline that 
serves this destination, so it is important to us.

Well, using cvs-head from today (8:30pm cdt) on a FC3 box, and calling 
American Airlines:
- calls via teliax iax2 completed normal
- calls via diamondcard iax2 completed normal
- calls via NuFone iax2 failed ("Sorry your call did not go
through...")
- calls via pstn (TDM04b) completed normal

All calls originated on a C7960 sip phone.

I'm using AAH 1.1 (Asterisk 1.0.7) w/ Teliax using IAX2.  I can 
successfully call those 2 numbers.  I'm using IP500 phone.
