Outgoing CLI

[ASCStech]

We have a customer CXIIi connected by IP trunks to our 3300 MXE. Both are running MCD 4.2. The customer site only has access to the PSTN via a PRI link on our MXE. The PRI link is dedicated for their use only. Problem is that their site is 3 digit numbering and our's is 4 digits and when it comes to outgoing CLI on their link only the main number is being presented. I have gone to add the 4xx to the CPN substitution form but as the current entries are 4 digit i cant add the 3 digit.
Is there any way to change the presentation of the outgoing CLI from the customer PABX over the IP trunks so that it presents 4 digits (94xx) instead.
The customer does not want 4 digit dialling on site.
Hopefully this makes sense.
Cheers

Can this not be done using associated directory numbers? If you look at the help section on cpn, you can do it in 2 ways system wide a dn based cpn. I believe system wide you cannot do it with multiple digit lengths.

Thanks MitelUK2010, associated directory number worked a treat.
Didn't really know that form existed or what it did.

Not a problem. Form can also be used to set up a hotline.
