25. 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.
