I have a 2821 router in Germany configured as a H323 gateway and is attached to an ISDN PRI line. The E1 PRI line is configured with primary-net5 ISDN switch type.
The problem is that about 5 inbound calls from the German ISDN network arrive with one digit short in the 'called number' field and more specifically the missing digit is the last digit in the number which makes it unique and routable to a specific destination. As a workaround I put in a dial peer that has a wildcard to catch these calls and send them to office main number, but unfortunately some of these calls that come in with the last digit missing are fax machines.
Does anyone currently have Cisco voice routers in place in any part of Germany? What ISDN switching type are you using? Have you ever encountered inbound calls with the most significant digit missing?
Any advice is appreciated. Thank you.
Ahhh the post from iptuser makes me realize that you may be very well just need "isdn overlpa-receiving", as germany has a variable-length dialplan. Proof of that, would be setups with the missing digit comes without "Sending complete IE" and is followed within 1 or 2 seconds by an info IE with the last digit.
Not having catch that before makes me bonk head on the keyboard.... sorry.
