Using CLID Callback
CLID stands for Calling Line Identification (i.e., calling parting number) which can be used by the ISDN CPE to call back without answering the call. The phone number used for calling back is captured from the D channel message. So, if your local ISDN switch is able to carry the calling party number, the Prestige can use this phone number to call back to the remote party.
There are two types of callback that the Prestige supports, they are the CLID callback and MS CBCP callback using Dial-Up Networking. Unlike the CLID callback, when using the MS CBCP callback the CPE must answer the first call to get the remote phone number from PPP CBCP negotiation and then call back to the remote party after hanging up the first call. In such a case, the remote party has to pay for the first phone call. While using the CLID callback, the remote party does not have to pay for the first call since the call is not answered. Therefore, you can not use Dial-Up Networking for the CLID callback since it does not support the CLID callback.
When calling back to a remote node the outgoing user information (username and
password) are configured in menu 11.1, Remote Node Profile. While calling back to a
dial-in user, the outgoing user information are configured in two fields in menu 13, O/G
Login and O/G Password.
Generally, there are several settings must be checked when using the CLID callback. They are:
