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.
Note: up to 500 extensions are allowed on the back/white list.
