Can multiple phones share the same extension for incoming and outgoing calls?

Each GreenLink extension can be set on up to 4 devices. This is designed for end-users that want to have a physical phone at home, and another at the office in addition to two devices on the softphone (mobile and laptop as an example).

Because multiple devices are allowed, designed for the same user, these devices can not be used at the same time.

This ability could be used to reduce monthly costs for extensions that are barely used.

An example of how this feature works 

Imagine you have a guest phone extension #152, and we need to have a guest phone in 4 separate guest areas, we can use the same extension and simply order 4 phones and have them configured to the same extension.
