C3945-CME-SRST/K9 Overview
C3945-CME-SRST/K9 is a Cisco 3945 router bundled with Voice Bundle w/ PVDM3-64, FL-CME-SRST-25, UC License PAK.
When Unified CME is used in SRST mode, it provides more call processing features for the IP phones than those are available with the SRST feature on a router. In addition, to the SRST features such as call preservation, auto-provisioning, and failover, Unified CME in SRST mode also provides most of the Unified CME telephony features for the SCCP phones, including:
- Paging
- Conferencing
- Hunt groups
- Basic automatic call distribution (B-ACD)
- Call park, call pickup, call pickup groups
- Overlay-DN, softkey templates
- Cisco IP Communicator
- Cisco Unified Video Advantage
- Integration with Cisco Unity with MWI support at remote sites, with distributed Microsoft Exchange or IBM Lotus Domino server
