The current status D Channel Callback will be displayed. Select 1 to toggle from disabled to
enabled (as shown by the following screen).
Note:
In addition to the CFGEDIT configuration changes, you must also do some configuration
through CSM for callback to work. You must define the calling device on CSM. For each
configured calling device make sure to:
•
Configure a calling line ID for the number the device will be using when calling into
the CyberSWITCH (located under the device’s Telephone tab).
•
Configure the telephone number to be used to call back to the calling device (located
under the device’s Telephone tab). This number is often the same as the CLID or
possibly with a preceding 9 if under Centrex.
•
Enable the Callback option (located under the device’s Access/Other tab).
•
Enable Outbound Authentication if you want to make sure the device you are calling
back to is the correct device (located under the device’s Access/Authentication tab).
For more detailed instructions, refer to the CSM user documentation.

When an incoming ISDN call is presented to the CyberSWITCH, certain information is presented
on the D Channel including the callers telephone number. Rather than accept the call right away,
the CyberSWITCH uses the calling line ID (CLID) to send a request to CSM to do a lookup based
on this CLID (as noted earlier, this option is only available if you are using CSM for device level
authentication). If CSM can find a device which has a matching CLID configured and that device
has callback enabled, we will reject the call being presented and wait for CSM to issue a call request
to the device previously identified. If callback is NOT enabled in CSM for this device or NO device
could be identified by this CLID, we will allow the call presented to be accepted and will proceed
to the authentication phase using PAP/CHAP/ etc. as usual.
