Hi all,
I have a box with an ISDN HFC card (1 BRI) connected to an Italian
ISDN, the card is using zaphfc driver and it's receiving and
originating calls quite regularly.
There are some numbers (mostly toll free numbers) that I cannot
connect to, here is what I get from the CLI:
-- Called 5/803868
-- Zap/5-1 is proceeding passing it to SIP/184-11da8730
-- Zap/5-1 is making progress passing it to SIP/184-11da8730
But it never foes any further, it just hangs like that waiting for the timeout.
My guess is the problem is related to the number being 'toll free',
It seems to me that card isn't 'detecting a remote answer' and is not
opening the audio channel.
Does it make sense ? I'm new to ISDN protocol ....
BTW, if I place the call with an FXO cards it works very well
Here is my system configuration, hope it helps
- Asterisk version is Asterisk 1.2.11-BRIstuffed-0.3.0-PRE-1s
- Libpri version 1.2.3
- Zaptel version 1.2.8
- Linux distribution: Gentoo
Tnx in advance for help
Regards
Edoardo
