[asterisk-users] Strange ISDN-problem with incoming calls out of the same city

[Stefan Guenther]

Hi,

after I fixed my problem with the playback() application, I now have the 
next strange one.

When I dial the number of our client, located in another town, I get a 
connection to the asterisk server, I can talk to my client or listen to 
his mailbox.

If some in the town of this client calls him, he gets the ISDN error 
"service not available".

Out office is connected to he office via vpn, and so I connected a sip 
phone to his asterisk server. Now this phone is in the same town and 
when I dial his external number (to make sure it is an ISDN connection), 
  I hear a single ring tone, then the phone is connected but I here nothing.

Here is the output of "capi debug":

What is the difference between an isdn call starting in the same area 
and a call from my office?

We are using a EICON DIVA Server 4 BRI with the current driver and an 
asterisk 1.4.13.

Here is the start of the capi.conf

[General]
nationalprefix=0
internationalprefix=00
rxgain=0.8
txgain=0.8
language=de
immediate=yes
faxdetect=off

[ISDN1]
incomingmsn=*
context=from-extern
ntmode=yes
controller=1
group=1
callgroup=1
accountcode=ISDN1
echocancel=yes
echosquelch=1
echotail=64
devices=2


Thanks for any suggestions,

Stefan
