I noticed that when calling different cell carriers sometimes you will get caller ID and sometimes you get unknown. For EVERY NBX install I now force the following:
Add a PreTranslatorISDNNumberType dial plan entry to specify Number Plan type for outbound calls to the CO. Normally, this dial plan entry is NOT needed. In some cases where certain numbers cannot be dialed out the PRI or BRI, this dial plan entry is required (specific to the dialed number and LEC/CLEC).
Example: You have a PreTranslator set up for Outbound Caller ID ( CLIP ) as ID #2. Here's the dial plan command that must be added to specify "national" as the ISDN Number Type for the CO to process the call
PreTranslatorISDNNumberType 2 2
- first value "2" specifies using for Pretranslator #2 (CLIP) - second value "2" specifies ISDN Number Type
ISDNNumberType types for ETSI are as follows: (0, default) unknown;
(1) international; (2) national; (3) network; (4) subscriber
Here is an example of where to type the entry:
PreTranslator Create 2 Outbound Caller ID
PreTranslatorISDNNumberType 2 2
/ PreTransId Entry Digits
/ ---------- ----- ------
PreTranslatorEntry Create 2 1 1
Why the hell isn't this a default entry? While I'm complaining why doesn't the dial plan have a web based GUI?
