Do you mean changing the Caller ID for outbound calls? There are a couple of places for that.
In CM, run the command
change public-unknown-numbering [length] ext-digits [dig string] where [length] is the number of digits in your extensions and [dig string] are the digits to match. For example, if your extensions are 4-digits and you want to set the caller ID for the entire 2000-2999 range, then your command would be:
Code:
change public-unknown-numbering 4 ext-digits 2 Page 1 of 2
NUMBERING - PUBLIC/UNKNOWN FORMAT

Ext Ext Trk CPN CPN
Len Code Grp(s) Prefix Len
Total Administered: 997
4 2 212555 10 Maximum Entries: 9999
4 3 2125552000 10
4 4199 2125552999 10
All 2xxx numbers are converted to 2125552xxx to match their DIDs
All 3xxx numbers are converted to 2125552000 since this range does not have DIDs
The specific number 4199 is converted to 2125552999 just because.
If you are using SIP trunks then you may be changing stations to DIDs in the Adaptation. In System Manager, look under
Elements / Routing / SIP Entities for your SBC. View the SBC to confirm there is an Adaptation. If there is, look under
Elements /Routing /Adaptations and click the appropriate Adaptation. You'll see two sections:
Digit Conversion for Incoming Calls to SM - Converts
Inbound calls from the SBC to Session Manager. You may see a Matching Pattern for the full number with deleted digits converting to an Extension.
Code:
[u]Matching Pattern Min Max Phone Context Delete Digits Insert Digits Address to modify Adaptation Data Notes[/u]
212555 10 10 6 destination Converts DIDs to Stations
Digit Conversion for Outgoing Calls from SM - Converts
Outbound calls from Session Manager to the SBC. You may see a Matching Pattern for the extension with inserted digits converting to a full number.
Code:
[u]Matching Pattern Min Max Phone Context Delete Digits Insert Digits Address to modify Adaptation Data Notes[/u]
