| Subject: | Outbound international calls over BT ISDN30 |
| Group: | Asterisk-users |
| From: | Stuart Ford |
| Date: | 29 Apr 2008 |
As always I'm trying the mailing list as a last resort as I'm out of
options. I am seemingly unable to dial international numbers over our BT
ISDN30 line.
I've checked with BT and the number format they're expecting is:
00<CC><number>
(where CC is the country code).
But this doesn't work. Looking at the PRI debug, the most notable error
seems to be:
Message type: DISCONNECT (69)
[08 02 82 81]
Cause (len= 4) [ Ext: 1 Coding: CCITT (ITU) standard (0) Spare: 0
Location: Public network serving the local user (2)
Ext: 1 Cause: Unallocated (unassigned) number (1), class = Normal Event
(0) ]
I've also tried different number formats, including:
+CC<number>
+0CC<number>
But to no avail.
Anybody know what I'm doing wrong? Here's a complete debug dump of a
failed international call to the US:
Many thanks
