About Dual Mode

Whereas Jabber is only active when registered, and Single Number Reach is controlled by manual toggle or schedule, Dual Mode allows  a Jabber Mobile customer to register their mobile number as a remote destination, tethered to the Dual Mode device.

  • When the device is registered, such as you recently opened or are using the Jabber client, calls will be sent to this client automatically.
  • If the Jabber client is unregistered, such as during a state transition (moving to Wi-Fi), the client is closed, or no mobile data, the Unified Communication Manager will sent calls to the supplied mobile destination automatically.

Why Dual Mode?

Cisco recommends using Dual Mode when receiving calls whenever possible is important to the Cisco Jabber customer. 

There are times when Jabber may not be available or connected, and a call may be coming in. In order not to miss it, Dual Mode will automatically fork the call towards a supplied remote destination.

With Single Number Reach, the system will always fork this call, treating the mobile device as an extra, separate phone.

If both the Jabber client and the mobile phone's dialer are ringing simultaneously, it may not be possible to answer either call.

Configuring Dual Mode

Note: Single Number Reach currently supports national US numbers only. International destinations are not allowed.

Common Questions

Do I have to request Dual Mode service?

Dual Mode is a standard part of Jabber mobile. If you have requested voice and video provisioning for a mobile device (iPhone or Android), the Dual Mode functionality is included.

Can I use Dual Mode and Single Number Reach?

Yes, but not with the same number.

  • You can enter additional destinations for Single Number Reach in the Self Care Portal. They don't have to be cell phone numbers, but could instead be a home number, or a SIP URI. They should not be another University number.
  • If you would like to force calls to your mobile at all times (not just on cellular data) while also using Jabber Mobile, configure Single Number Reach and not Dual Mode.
  • You can turn on and off Single Number Reach from within the Cisco Jabber client as well if needed.

I receive an error saying the destination is in use when I attempt to configure Dual Mode.

A mobile destination can only be used once. You cannot specify the destination as both a SNR destination at the bottom of the Self Care Portal and under Dual Mode at the same time.

If you believe this message is in error, contact the UBIT Help Center for assistance. Technical staff will locate the source of the issue.

Can I configure multiple destinations for Dual Mode?

No, only a single number may be configured. Configure the mobile number of the phone in use with Jabber Mobile. The service is not intended to be used with other numbers.

Will others see my mobile number?

No, the number is stored within the data systems and would only be visible to technical staff for troubleshooting purposes. Callers will not see your number.

Callers may, however, hear your mobile voicemail greeting depending on the circumstances of the call. Many providers, by default, read back the number reached in the voicemail greeting.

Can I still send calls to my mobile using Mobile Connect, while using Dual Mode?

Yes. When you select Move my call to mobile, the system will send the call to your Dual Mode Jabber client, if registered. It will otherwise ring your mobile number directly.

If you're leaving Wi-Fi or data coverage, and want to take the call directly on your mobile, without revealing your number (such as by transferring the call), either sign out of Jabber first, or use the Move to Mobile option within the Jabber Mobile client.
