Multiple Lines; Example - TANDBERG E20 Administrator's Manual

What's in this Guide? Introduction

Multiple lines

TE 2.1 supports multiple lines. This means that it supports registration of
multiple concurrent SIP profiles on the E20. Consequently, it is possible to
be registered with more than one Address-Of-Record at the same time. The
user can be reached through several SIP URIs at the same time and it is
possible to call using a specified SIP profile. One example would be the use
of a work (SIP-)profile for the home office and a private (SIP-)profile. Another
example would be a secretary using both a personal (SIP-)profile and the
(SIP-)profile for his/her boss.
There is one limitation to the multiple line support in the E20. In general,
it is not possible to use different lines to different types of SIP servers (for
example TANDBERG VCS vs OCS R2).
When dialing out from a system configured with multiple lines, you will need to
select a line before making the call. The available lines will be shown in a multiple-
line selection widget on the screen. The right-most softkey makes it possible to
put focus on the multiple-line widget enabling you to select the preferred line.

Example

TE 2.1 supports BroadWorks which is a software-based IP-PBX. You may
provision the E20 using the BroadWorks provisioning system. In addition to
supporting the BroadWorks provisioning scheme, TE 2.1 supports Shared
Call Appearance, Click-to-dial, Push-to-talk. The former is a concept based
on support for private and shared lines. Private lines are regular SIP-profiles
similar to the line concept in TE 2.0 and earlier versions.
A shared line is a BroadWorks extension supported in TE 2.1. It means that
several users (E20s with TE 2.1) can share a single line.
Whenever someone calls the shared line, all of the E20s
configured with this shared line will start to ring. Whoever
answers first will take the call. However, it is possible for
other users of the shared line to barge-in and join the call.

Using E20
Deploying E20 Using E20
Since Broadworks does not support video mixing in its current version, the
joined call will be audio only. As soon as one of the users disconnects from the
call, the video will be resumed.
It is also possible for one operator to put a shared line on hold and let
another operator resume the same shared call on another E20.
Click-to-dial is a concept where a web-based call-control manager can be
used to set up and tear down video calls between different devices. The
most common use case would be for a user to call another user from his/
her own E20.
Push-to-talk is a concept similar to a walkie-talkie where the calling user
will press the call button to immediately be connected to the remote party.
