This document explains how to configure Single Number Reach on Cisco Unified CME for both SCCP & SIP IP Phones.
Cisco Unified CME supports Single Number Reach for mobile users. The Single Number Reach (SNR) feature allows users to answer incoming calls to their extension on either their desktop IP phone or at a remote destination, such as a mobile phone. Users can pick up active calls on the desktop phone or the remote phone without losing the connection. Remote destination includes Mobile Phones, Smart Phones, Home phone numbers in PSTN.
1. Configuring Single Number Reach for SCCP IP Phones
The following example shows extension 1001 is enabled for SNR on IP phone 21. After a call rings at this number for 5 seconds, the call also rings at the remote number 4085550133. The call continues ringing on both phones for 15 seconds. If the call is not answered after a total of 20 seconds, the call no longer rings and it is forwarded to the voice-mail number 2001.
