For incoming calls to the SNR extension, Cisco Unified CME rings the desktop IP phone first. If the IP phone does not answer within the configured amount of time, it rings the configured remote number while continuing to ring the IP phone. Unanswered calls are sent to a configured voice-mail number.

The IP phone user has these options for handling calls to the SNR extension:

• Pull back the call from the remote phone—Phone user can manually pull back the call to the SNR extension by pressing the Resume soft key, which disconnects the call from the remote phone.
• Send the call to remote phone—Phone user can send the call to the remote phone by using the Mobility soft key. While connected to the call, the phone user can press the Mobility soft key and select “Send call to mobile.” The call is forwarded to the remote phone.
• Enable or disable Single Number Reach—While the IP phone is in the idle state, the user can toggle the SNR feature on and off by using the Mobility soft key. If the user disables SNR, Cisco Unified CME does not ring the remote number.
