More On CLID
CLID allows the Model RM356 Modem Router to authenticate a caller before a call is answered,
thus saving the cost of a connection. The router uses the caller ID information provided by the
telephone company during call setup to match against the CLID in the database.
Besides authentication, another application of CLID is to combine it with callback. For example, if
you enable both the CLID authentication and callback options for a dial-in user, all usage charges
are incurred by the company instead of the employee. This application may simplify accounting
and eliminate the necessity for reimbursement.
