Cisco SVS-CALL-ASST-SRST Call Assist SRST Gateway Configuration

Configure a new Cisco voice gateway with Survivable Remote Site Telephony (SRST) through a focused Call Assist professional-service engagement. SRST provides local call-processing continuity at a remote location when normal communication with centralized call control is unavailable. The stated scope combines new-gateway configuration with SRST rather than treating survivability as a separate activity. Use this service when a branch gateway must be brought into a Cisco voice environment with a local fallback calling function. The work concerns the gateway configuration and its SRST role; it is not a hardware gateway, software license, or general managed-support entitlement. SVS-CALL-ASST-SRST identifies the Call Assist service associated with that new-gateway and SRST scope. SRST is relevant where remote users need defined local calling behavior during a WAN or call-control outage. A gateway configuration service with SRST narrows the engagement to survivability-aware voice-gateway work, helping technical owners distinguish it from broader collaboration services. Review the intended gateway and site calling requirements before scheduling the service so the SRST configuration aligns with the remote site's operational calling plan.
