Hi , I have a site A and a site B that are SCN'd together via H323 trunks and the sets are 5420 digital sets. Certain execs would ideally like to have the same extension and voicemail at both offices. When they call internally they would like it to display the same extension number. When receiving calls, they want it to dump to the same mailbox. When messages are left, they want a message waiting indicator at both locations. Is it possible to do internal twinning across SCN? When I attempted it, I could not put in the target extension. Mobile twinning is not a complete solution because it still displays a different extension number when calling from secondary phone and the message indicator does not light. Any thoughts are appreciated.
