The new Barix SIP Zone Paging firmware, running on existing Barix hardware, enables system integrators to implement a zone capable paging solution without the need for a SIP client for each paging zone. Page routing is done in the Barix paging gateway and server. The big advantage of this solution: there is no complicated SIP server configuration required and only one SIP extension is required per simultaneous paging link. The solution overcomes the problems of prohibitive implementation cost for SIP solutions where the client needs to pay individual extension licenses for each connected zone.
