Fault: Can not add 0 to the beginning of the CLID being presented ( only 9 digits being sent )
The value in 10-02-03 will pre append Caller ID, this is used when the carrier sends Caller ID as 9 digit format.
This will work with:
-Analogue COT trunks
-ISDN trunks
-SIP trunks , ONLY if carrier is set to “G” in 10-29-14 , 10-02-03 is ignored if set to any other carrier type
