This action can be used by user's setup for mobile twinning. This action is not used for internal twinning.
While the phone is idle, the button allows the user to set and change the destination for their twinned calls. It can also be used to switch mobile twinning on/off and indicates the status of that setting.
When a call has been routed by the system to the user's twinned destination, the Twinning button can be used to retrieve the call at the user's primary extension.
In configurations where the call arrives over an IP trunk and the outbound call is on an IP trunk, multi-site network may optimise the routing and in this case the button may not be usable to retrieve the call.
Mobile Twinning Handover When on a call on the primary extension, pressing the Twinning button will make an unassisted transfer to the twinning destination. This feature can be used even if the user's Mobile Twinning setting was not enabled.
During the transfer process the button will wink. Pressing the twinning button again will halt the transfer attempt and reconnect the call at the primary extension.
The transfer may return if it cannot connect to the twinning destination or is unanswered within the user's configured Transfer Return Time (if the user has no Transfer Return Time configured, a enforced time of 15 seconds is used).
