Frequently Asked Questions
What is Cisco SRST?
Cisco SRST (Survivable Remote Site Telephony) is a feature that allows Cisco IOS routers to provide basic call processing and voice services for a local site when the main call processing system (like Cisco Unified Communications Manager) is unavailable due to a network outage.
What happens when the network connection is restored?
Once the connection to the central call processing system is restored, the SRST router will typically hand back call control to the main system. This ensures a smooth transition back to normal operations without manual intervention.
Does this license include the router hardware?
No, this is a software license for Cisco SRST functionality. It requires a compatible Cisco IOS router at the remote site to operate. The router hardware is a separate purchase.
