I know that German telco's commonly use Overlap send and receiving.
I have a 2811 as a voice gateway using H323 to talk to our CCM cluster.
The office uses a 10 digit number for the main reception switchboard and an extra digit for the DDI range for the extensions...
69 12 345 100 - reception
69 12 345 1001 - 1099 - DDI range
I'm seeing two things from the ISDN debugs...
Calls from within Deutsche Telekom seem to send the called party number for the DDI in the first setup message complete.
Calls from another Telco, come in with the first 10 digits, and then send the 11th digit in a separate setup message.
It tries to match the 2nd digit only at this point, and returns unallocated unassigned number.
What is the best practice config for Deutsche Telekom and this scenario?

incoming called-number .
I'm wondering if my incoming called-number is the problem. But this is the standard practice to avoid hitting the default dial-peer...
I will continue to debug.. but does anyone have experience with Deutsche Telekom specifically, and how they provide their circuits, and the best practice for setting up the CPE?
