Single Number Reach

Information About Single Number Reach

Overview of Single Number Reach

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. This enables callers to dial a single number to reach the phone user. Calls that are not answered can be forwarded to voice mail.

Remote destinations may include the following devices:

  • Mobile (cellular) phones.

  • Smart phones.

  • IP phones not belonging to the same Cisco Unified CME router as the desktop phone.

  • Home phone numbers in the PSTN. Supported PSTN interfaces include PRI, BRI, SIP, and FXO.

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 softkey, 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 softkey. While connected to the call, the phone user can press the Mobility softkey 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 softkey. If the user disables SNR, Cisco Unified CME does not ring the remote number.

IP phone users can modify their own SNR settings directly from the phone by using the menu available with the Services feature button. You must enable the feature on the phone to allow a phone user to access the user interface.

This feature is supported in Cisco Unified CME 7.1 and later versions on SCCP IP phones that support softkeys.

SNR Enhancements

Cisco Unified CME 8.5 supports the following enhancements in the Single Number Reach (SNR) feature:

Hardware Conference

In Cisco Unified CME 8.5, you can send a call to a mobile phone after joining a hardware conference. After joining the hardware conference, all conference callers are blind-transferred to hardware DN. The call character of the ephone changes from incoming call to outgoing call and you are able to send a call to the mobile.

Call Park, Call Pickup, and Call Retrieval

In earlier versions of Cisco Unified CME, Call Park, Call Pickup, and Call Retrieval features were not supported for SNR. Cisco Unified CME 8.5 and later versions allows you to park, pickup, or retrieve an SNR call,

Cisco Unified CME 8.5 enhances the SNR feature to allow you to see the local number on your cell phone instead of the calling party number. You can configure the snr calling number local command under ephone-dn configuration mode to view the caller ID of the SNR phone. For information on configuring SNR calling number local, see Configure Single Number Reach Enhancements on SCCP Phones.

Answer Too Soon Timer

On non-FXO ports, you can set an snr answer too soon timer to prevent the calls from rolling to the voice mailbox of your cell phone. When the cell phone rolls to the voice mail within the answer too soon timer range (1 to 5 seconds), the mobile phone call leg is immediately disconnected. You can configure the snr answer too soon command under ephone-dn mode. For more information, see Configure Single Number Reach Enhancements on SCCP Phones. The answer-too soon timer is not applicable when sending the call to a mobile.

SNR Phone Stops Ringing After Mobile Phone Answers

When SNR is deployed on non-FXO ports, if cell phone picks up an SNR call, you are connected to the call. The ephone stops ringing further and is placed on hold. You can configure the snr ring-stop command under ephone-dn configuration mode to stop the ephone from ringing and to place the phone on hold. For more information, see Configure Single Number Reach Enhancements on SCCP Phones.

Single Number Reach for Cisco Unified SIP IP Phones

Before Cisco Unified CME 9.0, the Single Number Reach (SNR) feature enabled the user to be reached on two numbers: a regular directory number (DN) on the ephone and a public switched telephone network (PSTN) connection (either a PRI/BRI/FXO port or a SIP interface). For incoming calls to the ephone, the Cisco Unified CME called the ephone DN first. When the ephone DN did not answer within a configured time, the Cisco Unified CME called a preconfigured PSTN number while continually calling the ephone DN.

In Cisco Unified CME 9.0 and later versions, the following SNR features are supported for Cisco Unified SIP IP phones:

  • Enable and disable the Extension Mobility (EM) feature on a Cisco Unified SIP IP phone—Use the Mobility softkey or PLK as a toggle or use the mobility and no mobility commands to enable or disable the Mobility feature on a Cisco Unified SIP IP phone.

  • Manual pull back of a call on a mobile phone—Use the Resume softkey to manually bring a call back to the SNR DN.

  • Send a call to a mobile PSTN phone—Send a call to the mobile PSTN phone using the Mobility softkey while the Cisco Unified SIP IP phone is on a call. Select “Send call to mobile” and the call is handed off to the mobile phone.

  • Send a call to a mobile phone regardless of whether the SNR phone is the originating or the terminating side—Ensure that the SNR feature is configured in voice register dn or ephone-dn configuration mode to send a call to a mobile phone regardless of whether the SNR phone is the originating or terminating side. Use the Mobility softkey, select “Send call to mobile,” and the call is handed off to the mobile phone.

For calls from a PSTN, local, or VoIP phone to a Cisco Unified SIP IP phone configured as an SNR phone, the Cisco Unified CME calls the SIP SNR or the mobile phone DN.

When you answer the call on the SIP SNR phone, you can send the call to the PSTN/BRI/PRI/SIP phone.

When you answer the call on the mobile phone, the Resume softkey is displayed on the SIP SNR phone and allows the call to be pulled back to the SIP SNR phone. You can repeatedly pull the call back from the PSTN phone to the SIP SNR phone or from the SIP SNR phone to the PSTN phone.

If the cfwd-noan keyword is configured and both the mobile and SIP SNR phones do not answer, the call is redirected to a preconfigured extension number when the end of a preconfigured time delay is reached.

The following shows how SNR phones configured with Cisco Unified SIP IP phones behave differently from those configured with Cisco Unified SCCP IP phones when sending a call to a mobile:

  • For Cisco Unified SCCP IP phones, the Resume softkey is displayed on the SCCP SNR phone as soon as the call is sent to the mobile phone.
  • For Cisco Unified SIP IP phones, the Resume softkey is displayed on the SIP SNR phone as soon as the mobile phone answers the call.

Note
When the Resume softkey is pressed, the call is returned to the SNR phone.

Cisco Unified CME 9.0 supports the SNR feature in Cisco Unified SIP 7906, 7911, 7941, 7942, 7945, 7961, 7962, 7965, 7970, 7971, 7975, 8961, 9951, and 9971 IP Phones.

Virtual SNR DN for Cisco Unified SCCP IP Phones

A virtual SNR DN is a DN not associated with any registered phone. It can be called, forwarded to a preconfigured mobile phone, or put on an Auto Hold state when the mobile phone answers the call or the time delay is reached. In the Auto Hold state, the DN can either be floating or unregistered. A floating DN is a DN not configured for any phone while an unregistered DN is one associated with phones not registered to a Cisco Unified CME system.

Before Cisco Unified CME 9.0, an SNR DN feature did not launch when the SNR DN was not associated with any registered phone. Although a call could be forwarded to the mobile phone using the call-forward busy command, the SNR DN had to be configured under a phone. Users who were assigned floating DNs could not forward calls unless they had a phone assigned to them.

In Cisco Unified CME 9.0 and later versions, an SNR DN is not required to be associated with a registered phone to have the SNR DN feature launched. A call can be made to a virtual SNR DN and the SNR feature can be launched even when the SNR DN is not associated with any phone. A call to a virtual SNR DN can be forwarded to an auto-attendant service when the preconfigured mobile phone is out of service and the voice mail can be retrieved using the telephone or extension number assigned to the voice mailbox.

Although the virtual SNR DN feature is designed for SNR DNs that are not associated with registered phones, this feature also supports virtual SNR DNs that complete phone registration or login and registered DNs that become virtual when all associated registered phones become unregistered.

Configure Single Number Reach

Configure Single Number Reach on SCCP Phones

Restriction:

  • Each IP phone supports only one SNR directory number.

  • SNR feature is not supported for the following:

    • SCCP-controlled analog FXS phones

    • MLPP calls

    • Secure calls

    • Video calls

    • Hunt group directory numbers (voice or ephone)

    • MWI directory numbers

    • Trunk directory numbers

  • An overlay set can support only one SNR directory number and that directory number must be the primary directory number.

  • Call forward no answer (CFNA), configured with the call-forward noan command, is disabled if SNR is configured on the directory number. To forward unanswered calls to voice mail, use the cfwd-noan keyword in the snr command.

  • Call forwarding of unanswered calls, configured with the cfwd-noan keyword in the snr command, is not supported for PSTN calls from FXO trunks because the calls connect immediately.

  • Calls from an internal extension to an extension which is busy, is forwarded to the SNR destination even if no forward local-calls is configured under the Directory Number.

  • Calls always remain private. If a call is answered on a remote phone, the desktop IP phone can not listen to the call unless it resumes the call.

  • U.S. English is the only locale supported for SNR calls.

    Configure Single Number Reach Enhancements on SCCP Phones

    Restriction:

    • Software Conference— After a software conference is initiated and committed on an ephone, you cannot send the call to a mobile phone. You can only enable or disable mobility after software conference is committed.

    • SNR Call Pickup on FXO port— For a call routed through FXO port to the PSTN, the call is signaled as “connected” as soon as FXO port is seized outbound. The mobile phone is on FXO interface and the call (session) is in active state as soon as FXO is in connect state. The ephone will be in ringing state but you can not pick up the ephone call.

    • Music on hold (MOH) is not supported if the SNR call originates from the line side. MOH is supported on an SNR call if the call originates from the trunk side.

        Step 11number number


        Example: 
        Router(config-register-dn)# number 1004
         

        Associates a telephone or extension number with a Cisco Unified SIP IP phone in a Cisco Unified CME system.

        • number—String of up to 16 characters that represents an E.164 telephone number. Normally, the string is composed of digits, but the string may contain alphabetic characters when the number is dialed only by the router, as with an intercom number.

         
        Step 12name name


        Example: 
        Router(config-register-dn)# name John Smith
         

        Associates a name with a directory number in Cisco Unified CME.

        • name—Name of the person associated with a given extension. Name must follow the order specified in the directory (telephony-service) command, either first-name-first or last-name-first.

         
        Step 13mobility


        Example: 
        Router(config-register-dn)# mobility
         

        Enables the Mobility feature on an extension of a Cisco Unified SIP IP phone.

         
        Step 14snr calling-number local


        Example:

        Enables the SNR feature on an extension of a Cisco Unified SIP IP phone.

        • e164-number—E.164 telephone number to call when the Cisco Unified SIP IP phone extension does not answer.

        • delay seconds—Sets the number of seconds that the Cisco Unified SIP IP phone rings when called. When the time delay is reached, the call is transferred to the PSTN phone and the SNR directory number. Range: 0 to 30. Default: 5.

        • timeout seconds—Sets the number of seconds that the Cisco Unified SIP IP phone rings after the configured time delay. When the timeout value is reached, no call is displayed on the phone. You have to use the Resume softkey to pull back or the Mobility softkey to send the call to a mobile phone. Range: 30 to 60. Default: 60.

        Note   

        When the default is enabled, the Cisco Unified SIP IP phone continues to ring for 60 seconds even if the remote phone answers the call.

        • cfwd-noan extension-number—(Optional) Forwards the call to the extension number when the phone does not answer after both the time delay and timeout values are reached. The extension number is typically the voice mail number.

        Note   

        This option is not supported for calls from FXO trunks because the calls connect immediately.

         
        Step 16snr ring-stop


        Example: 
        Router(config-register-dn)# snr ring-stop
         

        Ends the ringing on a Cisco Unified SIP IP phone after the SNR call is answered on the configured mobile phone.

         
        Step 17snr answer-too-soon time


        Example: 
        Router(config-register-dn)# snr answer-too-soon 2
         

        Sets the time in which SNR calls are prevented from being diverted to the voice mailbox of a mobile phone.

        • time—Time, in seconds. Range: 1 to 5.

         
        Step 18end


        Example: 
        Router(config-register-dn)# end
         

        Exits voice register dn configuration mode and enters privileged EXEC mode.

         

        Configure a Virtual SNR DN on SCCP Phones

        Restriction:

        • Virtual SNR DN only supports Cisco Unified SCCP IP phone DNs.

        • Virtual SNR DN provides no mid-call support.

          Mid-calls are either of the following:

          • Calls that arrive before the DN is associated with a registered phone and is still present after the DN is associated with the phone.

          • Calls that arrive for a registered DN that changes state from registered to virtual and back to registered.

        • Mid-calls cannot be pulled back, answered, or terminated from the phone associated with the DN.

        • State of the virtual DN transitions from ringing to hold or remains on hold as a registered DN.
