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.

D CHANNEL CALLBACK CONFIGURATION ELEMENTS

CALLBACK STATUS

You may select to enable or disable the callback feature for devices using CSM for authentication.

DCHANNEL CALLBACK BACKGROUND INFORMATION

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.
