Black/White List in IVR

In some scenarios, the IPPBX administrator needs to restrict the extensions that can be reached from IVR.
For example, the company CEO and directors prefer only receiving calls transferred by the secretary, some
special extensions are used on IP surveillance end points which shouldn't be reached from external calls via IVR
for privacy reason. UCM has now added blacklist and whitelist in IVR settings for users to manage this.
To use this feature, log in UCM web UI and navigate to PBX->Call Features->IVR->Create/Edit IVR: IVR
Black/White List.

If the user selects "Blacklist Enable" and adds extension in the list, the extensions in the list will not be
allowed to be reached via IVR.

If the user selects "Whitelist Enable" and adds extension in the list, only the extensions in the list can be
allowed to be reached via IVR.
