GRP261X BroadWorks SCA Configuration Guide

INTRODUCTION

Grandstream GRP261X SIP phones support BroadWorks Shared Call Appearance feature. Shared Call Appearance allows multiple phones to share one extension number and manage a call as a group. Incoming calls will appear at multiple locations simultaneously. All devices where call appearance is shared can be used to answer an incoming call or make a call as if it is the main user. Calls can be transferred between two phones by simply putting the call on hold at one phone and picking it up on the other. Line keys light up or flash in different colors, allowing all people sharing the extension to monitor the call status. One important application for Shared Call Appearance is for an administrative assistant/executive scenario.

This document serves as an end-user guide on how to configure Grandstream GRP261X SIP phones for the BroadWorks Shared Call Appearance feature. How to configure SCA on BroadWorks Application Server is out of the scope of this document. System Administrators shall check BroadWorks Partner Configuration Guide for more detailed information.

KEY CONCEPTS

Line – One address-of-record as defined in RFC3261 represents one line. Line can be classified as being either “Private” or “Shared”.

Call Appearance – Every call is associated with a specific line. The presentation of a call on a line is called “Call Appearance”.

Shared Call Appearance – A Shared Call Appearance is any Call Appearance that is visible and accessible (optional) to the original endpoints as well as other authorized endpoints.

Public Hold – The held call is available for any shared line to retrieve.

Private Hold – The held call can only be retrieved from the shared line that held the call.

Bridging – Join an active call to form a multi-party conference.

SCA CONFIGURATION ON GRP261X PHONES

Configuring Grandstream GRP261X SIP phones to work with BroadWorks Shared Call Appearance feature is straightforward. First, configure the SIP account settings just as you would for a normal SIP account. Then set the Line Key mode of the corresponding Line to be a Shared Line.
