We have a DDI range in the office which needs to be diverted out back to the PSTN to another DDI range.
We have CCM 4.1 with a ISDN30 for a PSTN connection,
I know I could enter the destination full DDI number on each DN we have but I was hoping to achieve the same on the whole DDI range and saving myself lot of hassle. Also the Phones will be removed from the site with only the CCM servers and the ISDN circuit left in place.
For example I need to forward
All numbers inbound to call manager back out to the PSTN with just the first 6 digits changed and leave the last 2 digits the same
If you need more details to understand then please ask.
