Issue 18.b.- (08 July 2008)

Twinning and Mobility

Twinning allows a primary extension and a secondary number (extension or external) to operate together as a

single telephone, When a call is presented to the primary phone the secondary will ring. If the primary

telephone does not ring, for example in Do Not Disturb, the secondary phone will not ring.

Internal Twinning

This is typically used in scenarios like workshops or warehouses where team supervisors may have a desk with

a fixed phone but also have a wireless extension (e.g. DECT). When a call is made from either twinned phone,

the call will appear to have come from the primary phone (when the secondary is an extension on the IP Office

system). Other users of the system need not know that the supervisor has two different phones. The

supervisor’s Coverage Timer and No Answer Time are started for the call and if the call is not answered within

that time, the call will be delivered to available coverage buttons (if applicable) and then Voicemail (if

applicable).

Mobile (external) Twinning

A typical use for Mobile Twinning would be for a salesperson who has a desk extension but is often out of the

office. They can give out one phone number to clients, but it will ring their mobile/cell phone as well as the

desk extension. External mobile devices can be set as twinning targets even if the primary telephone is logged

out (e.g. in the case of a “virtual” extension).

From IP Office 4.2 onwards, the following additional Mobility features are available in addition to simple mobile

twinning (but need to be separately enabled per user in IP Office Manager):

Mobile Call Control

This allows a user who has answered a twinned call on their mobile phone to dial a DTMF sequence

**(star-star) to put the call on hold and receive IP Office system dial tone. The user will then be able to

perform supervised and un-supervised transfers, shuttle (switch between held calls), and conference

(Conference add and transfer to a meet-me conference).

Avaya one-X™ Mobile Client Support

IP Office 4.2 supports the Avaya one-X Mobile “Single Mode” Client running on selected Symbian Single-Mode

or Windows Mobile 5 or 6 handsets. This provides a graphical interface for call control and allows a

one-number service for both incoming and outgoing calls. For a full list of supported handsets see

http://support.avaya.com. IP Office systems supporting one-X Mobile require a dedicated DID/DDI number for

each feature required (e.g. hold, transfer).

Mobile Call Control and one-X Mobile support require twinned calls to be routed through specific trunk types on

IP500 only:

· IP500 PRI-U (single or dual) daughter cards

· IP500 Dual or Quad BRI daughter cards

· SIP trunks (RFC 2833)

In IP Office 4.2 the existing Mobile Twinning license has been renamed to Mobility license. The license now

enables the use of Mobile Call Control and one-X Mobile client features as well as Mobile Twinning. An instance

of the license will be consumed for every user who has Mobility Features checked in IP Office Manager.

With either internal and external twinning, users may be allowed to enter a twinned number, or may just be

able to activate/deactivate the twinning function depending on administrative settings. Such user activation

can be achieved through deskphone buttons, Phone Manager or VoiceMail Pro.
