Cisco IOS Software Release 12.2(4)XW

Introduction

This product bulletin describes the survivable-remote-site-telephony (SRST) feature introduced in
Cisco IOS® Software Release 12.2(4)XW for the Cisco 175x modular access routers.

New Features

The SRST feature provides the Cisco CallManager with fallback support for the Cisco IP phones attached to the router on your local Ethernet. It is currently supported on the Cisco 2600, 3600, 3810, IAD 2400, and Catalyst® 4224 platforms. With 12.2(4)XW, the SRST feature is introduced to the Cisco 175x Series routers.

Prior to SRST, when the WAN connection between the remote branch-office router and the Cisco CallManager failed, or connectivity with the Cisco CallManager was lost for some other reason, the Cisco IP phones at the branch office became unusable for the duration of the failure. SRST was developed to overcome this problem. The feature provides call-handling support on the branch-office router for its attached Cisco IP phones when a failure occurs. The system automatically detects the failure, and using Simple Network Auto-Provisioning (SNAP) technology, auto-configures the branch-office router to provide call-processing service for the local IP phones. When the failure is restored, call-handling capabilities for the Cisco IP phones switch back to the primary Cisco CallManager. During a failure, the Cisco IP Phone displays a message to inform the user that the Cisco IP Phone is in the Cisco CallManager fallback mode and is able to perform a limited set of functions.

By providing SRST features on the Cisco 175x routers, Cisco is reducing the likelihood of voice-service disruption, giving its customers the confidence to deploy multiservice e-business applications that will enhance employee productivity and reduce costs.

The SRST provides the following features on the Cisco 175x:

Rehoming of IP phones to a local router when WAN failures occur

Maintenance of local extension-to-extension calls

Maintenance of extension-to-Public Switched Telephone Network (PSTN) calls

Maintenance of existing calls upon recovery

Support for IP and basic-telephone-service (POTS) phones

Speed dial and last-number redial

Direct-outward-dial calling

Direct-inward-dial calling

Caller ID and automatic-number-identification (ANI) support

Calling-party name

Distinctive ringing

Transfer (without consult)

Call hold and pickup

Call park and retrieve

Call waiting

Up to six lines per phone

Up to 24 phones and 48 line appearances per system

SRST is supported in one image set IP/VOX PLUS for the Cisco 1750, and it is supported in all image sets containing VOX for the Cisco 1751. For details, refer to "Product Numbers and Descriptions" section.
