Call Authorization
Restrict outgoing calls to customizable numbers and manage authorizations

Service Description

Call Authorization

The Call Authorization service permits the operator to offer its corporate customers the possibility of restricting outgoing calls to their users, and allow them only to users who have the authorized PIN.

When a user wants to make a call that is restricted, a locution prompts them to enter the PIN code. If it is correct, the call is established. Otherwise a voicemail is issued and the call is terminated.

How it works

Outgoing calls are routed to OCCAS, which consults in LDAP/HSS or another external database both the caller number and the called numbering. In the case where the call is restricted, OCCAS will request the MRF for the locutions requesting the PIN in order to establish the call. If the PIN entered is correct, the call is routed back to the IMS to be processed. If the PIN is not entered or is incorrect, the call is rejected.
