Extension virtualization allows people to get independent of the phone device phone device their extension is configured on. Mostly recommended to call center agents, creating a virtual desk that requires very little configuration.

Set up a secret code

Virtualization works by means of secret code that needs to be set for the extension that will be moved, i.e. the virtual extension.  

To set up a secret code from the interface of the virtual extension, click on the Phone Terminal Setup icon, scroll down to the Extension Virtualization fieldset, and fill in the Set secret code field.

...

When the extension is virtualized, all fields detailed below are displayed in the interface.

• Set secret code   [ ]: A numeric code of 4-8 digits, which enables the extension to be moved to any phone device tied to any to any extension within the same organization that allows virtualization.  The The code must be kept secret.  Once Once this code is set, the label will change to Replace secret code.
• Existing secret code:  Displayed only if such a code has been previously set.
• Currently virtualized on     on <BaseExtension> Return to Base:  Displayed only if this extension is virtualized.  <BaseExtension> stands stands for the extended number of the base extension where the extension is virtualized. Return to base is is a link that triggers the return to base of the virtualized extension.

...

By default extensions are configured not to accept virtualization because during virtualization the base extension becomes unavailable. Therefore, you need to enable to enable virtualization only if you want you or any other member of the organization to use the phone device where your extension is provisioned.

...

To enable this option from the interface of the base extension, click click on the Provisioning and SIP icon, scroll down to Extension Virtualization fieldset, and select the Allow virtualization on this extension option.

...

Virtualize your extension to a phone devicephone device

You can use your extension on any phone device in the company that carries a base extension that allows virtualization.

To do so, you must pick must pick up the phone and dial the Virtualization Center number, followed by the by the short number of the extension that you want to virtualize:   *30<extension_short_number>. You will be asked for the secret code you set up in the interface.

...

• all calls to the user's extension (the virtual extension)  will will ring on the phone device where virtualization was carried on
• while the user is using another physical device for their extension, the phone device tied to the virtual extension will not longer ring/allow to dialout, but will always allow the user to move their virtual extension back to the device
• all calls to the base extension during virtualization will go to Voicemail because the base extension is no longer active in the system

...

There are two methods by which you can return your extension to the phone device it was previously tied to:

Method #1: Dial the Virtualization Center Number (*30).

Method #2: Log in to the web management interface of the virtualized extension, go to Extension (name)  -> > Phone Terminal Setup page, scroll down to the the Extension Virtualization fieldset and fieldset and click on the Return to base link next to the Currently virtualized on field.

...

• The virtual extension B is virtualized on phone provisioned by extension base A
• The owner of extension C picks up the phone where extension base A is provisioned and attempts to virtualize extension C
• The operation is successfulis successful, meaning that extension C is virtualized on extension base A and extension B returns to its phone device

...

So basically the physical terminal of B is used as a base and at the same time B is virtualized. Even if the user tries to unvirtualize (return to base) from its own physical extension or from the virtualized extension, it will be unvirtualized on request, without the need to provide any password.  If If *30 is dialled from is dialled from the physical terminal of B, then A will be unvirtualized. Then, if *30 is dialled againis dialled again, extension B will return to its to its own physical extension.
