Since 188.8.131.52 of Lotus Sametime Unified Telephony a subscriber can register as the primary line from more than one keyset device at the same time - without requiring additional dynamic licenses.
Before 184.108.40.206, when a primary keyset line L
was already registered from a device D1
, the attempt to register from another device D2
resulted in L
being unregistered from D1
. Additionally, all secondary lines registered for D1
were also automatically unregistered. Starting with 220.127.116.11, L
can now register from both D1
(similar to a multiple contact scenario).
The phones using the same primary line are not required to have the same secondary line configurations. For example, a phone may have three secondary line appearances, while another phone may have only one of them.
The number of bindings (registrations) for a primary line is subject to the same pre-set limits as for regular keyset lines. The maximum number of bindings for a keyset line is configured to a default of 40, i.e. by default the number of prime lines plus secondary lines can't exceed 40. Once that many bindings are in the system for that particular line, attempts to register another contact address will be rejected. Please do not change the default configuration without consulting your service partner.
An executive can now
- answer a call using her desk phone
- put the call on hold on the desk phone
- walk to the conference room, where another phone with the same primary line is configured
- retrieve the call on the conference room phone and continue talking
Before 18.104.22.168 this could have only been solved by configuring the executive's phone number as a secondary line appearance of the conference room phone. However, this requires a different primary line for the conference room phone and hence an additional dynamic license.
