I would like to limit the access to DISA (and define a correct outbound callerID as well).
I did already used the inbound CID and it does work fine but requires 1 entry for each CID.
Is there a smarter way? similar to managing a list of CIDs allowed to use this DISA.
The PIN is not a good enough solution because of employees turnover (while the mobile phone number (CID) is provided to the employee with the hardware and can remain allowed most of the times).
Thx for your help.
