Help with DID Ranges for CPN Substitution

[lemb]

I've been requested to configure certain extensions that when they dial out the they want to have a perticular number show up on Call Display. There are already a bunch of DID Ranges that have already been configured.

The Extensions they want changed fall within the previously defined DID Ranges. Can I simply add the new DID with CPN Substitution or do I need to first exclude the ext from the current range.

For Example:

Index    DID Range    CPN Substitution
1          100-199        4444444xxx
2          150              5555555xxx

Or does it need to be like

Index    DID Range    CPN Substitution
1          100-149        4444444xxx
2          150              5555555xxx
3          151-199        4444444xxx

Thanks

I believe you can do it either way, the system will use the most specific mask you may have defined. As a third option you can also do:
1     100-149,151-199    4444444xxx
2     150                          5555555xxx

Remember you'll need to add the 2nd index to your digital trunk, and reload the card to get the updated existing index to update on the card itself.

Of if your software version supports it, use the Associated Directory Number form to define a specific CPN sub.
