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

before we switched from the old pbx to the asterisk server, these people 
had no problems calling our client.

With some more debugging we saw what happens with these specific calls.
For some reason local calls and calls from a few other cities cause 
trouble, because asterisk doesn't get the whole number that has been 
dialed. If e.g. someone from the same town dials 123456, asterisk only 
gets  12345 or 1234. This extension doesn't exist in the dialplan and so 
the call fails. And this is not a single failure, it happens every time.

The telco has checked the lines and they are okay, so it might be the 
ISDN card (EICON) or the driver. I have made a trace log from one of 
these failed calls and will forward it to EICON.

Meanwhile we catch all these calls with the "i" extension.

Stefan
