Detailed Information

Survivable Remote Site Telephony
Enterprise customers wishing to deploy IP telephony at their branch offices using a centralized Call Manager architecture are very interested in call-processing redundancy capabilities at these remote sites. Such redundancy ensures negligible impact to the business in case a Wide Area Network outage prevents the centralized Call Manager from being able to process telephony requests from IP phones at the branch office. The Survivable Remote Site Telephony feature integrates call processing capability directly into OS, enabling the 2600 or 3600 Series router at the branch office to provide telephony redundancy.
IOS Telephony Services - IP-Keyswitch
The IP Key-switch function integrates call processing in IOS for enterprise branch offices or for service provider managed services for Small Medium Businesses. Customers that use Cisco 2600 or 3600 series multi-service routers can now add this capability by a simple IOS software upgrade, and provide integrated telephony services for IP phones such as the Cisco Telecaster 79xx. A rich set of phone features are also supported such as orwarding, transfer, hold, multi-line appearance, etc. The IP Key-switch function will support up to 48 phones or IOS devices depending on the platform.For further information please see the 12.1(5)YD release notes: from the link below.
