Outbound Caller ID Name may be added to most of our Tier A DID numbers. This allows you set the name people see on their caller ID when you make calls for a specific DID number. Retail customers incur a one time charge of $10 for each DID number that requires updating. It may take up to thirty days for outbound caller ID name to work. This is because the telephone directory LiDB takes time to update. Caller ID name is not a dynamic automatic feature.
