IPs change.  Also, the client may not have ordered the service from the 
office.  They may have bought the service for multiple locations from 
head office.  Too many variables.

You may have to think about hardware.  Some sort of RF device installed 
at the client with a unique ID.  The employee waves his keychain at the 
device, it connects to your office and sends the employee's ID and its 
own.  A card reader is another possibility or bar code reader.

Of course that's not a phone solution so I guess it is off topic here.
