The is a specific Cisco IOS software image designed for the Cisco 2691 Multiservice Router. This image belongs to the Advanced IP Services feature set (indicated by advipservicesk9 ), which provides a comprehensive suite of networking capabilities, including high-end security and advanced IP routing features. Overview and Capabilities

Offers advanced voice features like SIP, H.323, MGCP, and Voice Gateway capabilities, making it excellent for legacy voice lab testing.

: The C2691 is a MIPS-based router and is perfectly supported by the Dynamips emulator, making it faster and less resource-intensive than virtualizing newer IOS-XE devices. It is widely used in network simulations (GNS3/EVE-NG)

支持可存活远程地点电话（SRST），为IP语音通信提供本地冗余支持，即使与总部之间的WAN链路中断，分支机构的内部通话也不会受影响。
