The new enhancements in the IP Office Restrict Network Interconnect feature apply to endpoints and trunks. Calls can be made to or from IP phones to local PSTN public trunks only if the location of the IP phone is the same as the system location. No extra licenses are introduced as part of this enhancement. The feature is supported on IP500V2/IP500V2A/B and IPOL and in all the editions such as Essential, Preferred, or Select.

A Distributed user, A, receives a PSTN call originating from Site A. The Distributed user, A, forwards the call to a Centralized user, C, in Site A. This PSTN call is allowed because the locations of the originating call and the terminating call are the same.

A Distributed user, A, receives a PSTN call originating from Site A. The Distributed user, A, forwards the call to a Distributed user, E, in Site B. This PSTN call is not allowed because the locations of the originating call and the terminating call are different. There is no restriction on Enterprise calls or non-PSTN calls. The SCN scenario is similar for non-PSTN calls for the Primary IPOL server instead of the Avaya Aura® Communication Manager and Avaya Aura® Session Manager.
