[Asterisk-Users] Grouping lines pending on Called ID

[Daniel Nyström]

I will be using one E1 to the telco, and there will be 4 static phone numbers, and one number serie with 1000 numbers ranging from e.g. 555-1000 to 555-1999.
There will be 30 FSX lines on the other side of Asterisk.
Is it possible to "group" those 30 FSX lines pending on which number was dialed?
Let's say line 1-4 are for the static numbers, and 5-30 for the other 1000 numbers.

Are there any documentation with this issue?

Best Regards
