CallerID is not dropped if balance is zero

1. Make sure you have the functionality Leave CallerID assigned to Card when balance is empty disabled 2. If it is disabled and the user made a call and balance is zero and the callerID is there, there are a few reasons for this:

• CallerID was not dropped because the user in the same call can use Calling card top up to increase their balance on the card
• CallerID will be dropped once the user makes a new call to the system and the system will ask for new PIN
