Fellow Asterisk-Friends,
currently I’m implementing a Asterisk Server which is attached over e1 on our company’s phone system. The server should provide SIP phones the possibility to connect with and call internal or out to phones in our telecommunication system.
However I face with the problem, that the external trunk (e1) will not get up, outgoing calls brake up with the message
[Jan 20 14:14:07] VERBOSE[3950][C-00000002] sig_pri.c: -- Requested transfer capability: 0x00 - SPEECH
[Jan 20 14:14:07] VERBOSE[3950][C-00000002] app_dial.c: -- Called DAHDI/g1/1354
[Jan 20 14:14:15] VERBOSE[3763][C-00000002] sig_pri.c: -- Span 1: Channel 0/2 got hangup, cause 18
[Jan 20 14:14:15] VERBOSE[3950][C-00000002] chan_dahdi.c: -- Hungup 'DAHDI/i1/1354-3'
[Jan 20 14:14:15] VERBOSE[3950][C-00000002] app_dial.c: == Everyone is busy/congested at this time (1:0/0/1)
I tried with number 1354 (my deskphone) and 01354 (0 as prefix) and also the complete number with region information etc.
Configuration
Sangoma A104DE E1 Card
E1 line as External Trunk on our company’s telephone system
Versions:
* Asterisk 11.7 - latest
* Libpri 1.4.14 - latest
* Dahdi 2.8.0.1 - latest
* Sangoma wanpipe drivers 7.0.8

I don’t know much about asterisk and E1 
and it would be great if someone could help me?
Do you need further informations on my implementation?
Thank you in advance!
