Cisco Unified Survivable Remote Site Telephony (SRST) provides critical backup telephony functions at remote
branch offices when connectivity to the centrally located Cisco Unified Communications Manager fails (that is,
the WAN link is interrupted). During WAN outage the Cisco Unified SRST-enabled router provides robust
telephony services (including off-net calls to 911). This product is ideal for enterprise organizations looking to
cost-effectively deploy IP telephony in their branch-office locations. Cisco Unified SRST is available on the
Cisco 880 Series, 1861,and 2800 and 3800 Series Integrated Services Routers and the Cisco Catalyst 6500
Series Switches using the Cisco Communications Media Module (CMM).
Key Features
• Business resiliency is achieved through redundant, localized call processing with intelligent and automatic
failover configuration—no manual IT or telecom intervention is required.
• This single appliance device is ideal for routing, security, public switched telephone network (PSTN) gateway
services, and call control during WAN outages.
• Cisco Unified SRST supports all Cisco Unified IP Phones, supporting 8 to 730 phones per platform.
• All common PSTN interfaces and protocols are supported, in addition to support for both internal and external
calling during failover with calls maintained during failover and fall-back.
• Voicemail is supported during WAN outages with local Cisco Unity Express or centralized Cisco Unity unified
messaging through the PSTN.
