General understanding problems, Incoming Calls, Trunks, Outbound Routing, DID Routes? And what about localisation?

Hi!

By now I've got some problems understanding the whole AMP/Asterisk stuff.

I want to use AMP/Asterisk with two HFC ISDN-cards so I need some custom 
changes.

So is the "Incoming Calls"-section in any way important for me? I see 
the problem in the fact that there I can tell the system _exactly_ one 
extension that is to be called. But since I have got an ISDN line with 
100 possible extensions (-0 to -99) this isn't suitable for me. Or am I 
wrong?

At the trunks I'm asking myself if I have to use the custom trunk for my 
ISDN line (we will not use SIP or IAX) or the ZAP trunk since the 
BRIStuff-patch seems to modify ZAP.

Another problem exists in the fact that I don't really know how to 
implement the german patterns. The german systems differs totally from 
the US system. In germany the numbers have different length. Not only 
the local numbers can be different in length but also the long distance 
numbers for different cities.

Example:
Hamburg has go the Number 040
Hannover is 0511
Celle is 05141

When I'm in Celle and want to dial the local number 123123 I only have 
to dial 123123. When I want to dial the Number 321321321 in Hamburg I 
have to dial 040321321321.

The length of the city number plus the local number isn't static as 
well. In my city some local numbers got 4 digits, some others 5 and the 
rest 6.

How can I define that? If I want to make an external call with my system 
I want to dial the number as a prefix "0". So if I want to call the 
local number 123123 I dial 0123123. If I want to dial to Hamburg I dial 
0040321321321.

If somebody could help me I would be very glad.

Another problem: By now all announces are in english. Are there any 
german announces available?

Thanks!

Michael
