[asterisk-users] PRI hangup certain outgoing calls
I have a problem calling a certain number from our PRI line. Calling the
number from a separate PSTN phone works fine.
The remote number seems to have some funny call redivert setup, when you
call it, it answers immediately, makes some kind of beep and then starts
to ring.
Our PRI is in the UK from Telewest/NTL/Virgin Media and most outgoing
calls work without a problem. The server is trixbox based with a Digium
TE410P PRI interface. Trixbox 2.6, Asterisk 1.4.18-3, FreeBPX 2.4.
I'm no expert, but the PRI trace shows that the outgoing call is
proceeding, and then seems to show that my end of the connection has
disconnected the call, but I cannot work out why - it has already agreed
to setup the call!
What is causing this disconnect? Is there some tone detection going on
behind the scenes?

I believe the issue is a bug in channel locking in Asterisk 1.4.18. I'm waiting for Asterisk 1.4.19 to be released through Trixbox, which has bugfixes applied to fix this exact issue. This is the section to focus on. Sorry I cannot be of much help. Can you dial other numbers, it is just an issue with one in particular? http://www.voip-info.org/wiki/view/Asterisk+variable+hangupcause #define AST_CAUSE_NORMAL_CIRCUIT_CONGESTION 34 #define AST_CAUSE_NO_ROUTE_TRANSIT_NET 2 (this is fishy) I would contact your service provider, they may be able to explain it better if not fix it.

If so, try sending your BTN or some other regular toll number. I had a similar problem dialing a specific number (Gateway) when sending a toll free callerID, GXing said it was because other telcos are unsure how to bill the call so they send back busy.
