[cisco-voip] DID ranges with an offset?

[Kelemen Zoltan]

Hi!

I was wondering if anyone has a decent idea, how could I route a block 
of 100 numbers (...9XX) to two blocks of 50, partially overlapping in 
their last two digits, short of a ton of translation patterns?

So, I have incoming: 39XX
and inside we have 1XX and 2XX extensions, where the last two digits 
partially overlap from the two groups.

I can have 00->49 translate directly to the 1XX range, so that's a 50% 
improvement :)
but how can I translate (easily) the last 50 into 2XX?

Changing the existing extensions is not really an option, but something 
like 39XX translated into 2XX-50 (that's a minus :-) ) could work for 
me. Like 3950->200, 3965->215 and so on ...

It's a CCM 4.1.3, with a MGCP controlled PRI line.

thanks,
  Zoltan
