please dont you know if there is a possibility within CUCM 7.1 to route calls according to some database.
The thing is, that here we gotta several GSM providers and they dont have strict numbering plans, which means that if you want to change
provider of your GSM phone and you dont want to change your number it is possible.
But problem for our call routing is that we would like to buy lines to every provider and we can also get dbase of numbers (which belong to which
provider) but I dont know how to make routing work according to this dbase. Simply said, we cannost setup route patterns like this
1XXX - provider A
2XXX - provider B
3XXX - provider C
because there can be numbers in extension 1XXX belonging to provider C, and so on.
Do somebody got idea?
