winner N3 Voice Service Survivable Remote Site Telephony (SRST) SRST is a licensed product which runs on a CISCO router enabling that router to take on limited functionality of a Call Manager in the failure scenario where the connection to the N3 Network has been lost. SRST on it’s own allows internal calls within that site to be made to and from all handsets which have been designated SRST handsets. To provide resilience the SRST router is hosted on a free LAN port on the Customer’s or N3 supplied LAN switch. Survivable Remote Site Telephony (SRST) with Local PSTN Access For sites with existing PSTN connections by upgrading the SRST router hardware to include as appropriate a BRI or PRI card (for ISDN2/30 connection) the router can be configured in such away that should the site become isolated from N3 Network, calls could continue to be made and receive via the local PSTN connection. In addition those handsets not included in the list of designated SRST handsets could have CFUR (Call Forwarding Un-Registered) to point either to a PSTN or mobile number or alternatively to one of the SRST enabled handsets extension number.
