Shared Call Appearances - External Calls
Feature Description
Shared Call Appearances (SCA) were implemented to address the request for key system features like call appearances and the public hold (a.k.a. transfer on hold) capability. The Shared Call Appearances feature provides the following functionality:
- Presents external calls on programmable keys on XSTIM extensions (SCA keys)
- Multiple XSTIM extensions can be configured to have the same SCA key(s)
- Once a call is assigned an SCA ID, all extensions with the corresponding SCA key provide indication of the call state via icons or indicators (on XSTIM IP nad/or digital phones)
- While an SCA call is ringing, any extension on which the call is ringing or presented to (see Configuration Step 4 on how to configure a non-ringing SCA key) can answer the call by going off-hook or by pressing the Answer softkey or the programmed SCA key
- If an SCA call is put on hold, users of all phones with the corresponding SCA key can press that key to retrieve the call
Introduction
From the end user perspective
- SCA keys implement call appearances that can be shared by any number of XSTIM extensions
- SCA keys provide “public hold” or "transfer on hold" functionality
- SCA keys provide visibility of how many SCA calls are active
- SCA keys can uniquely identify trunks (configuration of SCA keys is based on inbound and outbound routes – when a unique inbound and outbound route is used for each trunk, one or more SCA keys can be configured to directly correspond to each trunk)
- SCA keys can be configured on expansion modules (with SCA, the number of active calls on a phone is not limited by the number of programmable buttons on the phone itself)
Pre-Requisites
None.
Configuration
Step One: Configure Ring Group
This step is optional. You need to configure a ring group only if you want multiple phones to ring or be alerted on an incoming SCA call.
- Open the UCX Web-based Configuration Utility
- From the PBX tab, select PBX Configuration
- From the left side column under Inbound Call Control, select Ring Groups
-
Fill in the following required fields:
- Ring-Group Number - the number to dial to reach this ring group
- Group Description - a description for this ring group
- Extension List - the list of extensions to present the call to
- Destination if no answer - select the destination if none of the extensions in the group answers
- Press the Submit Changes button
Step Two: Create an Inbound Route
To add an inbound route, perform the following steps:
- Open the UCX Web-based Configuration Utility
- From the PBX tab, select PBX Configuration
- From the left side column under Inbound Call Control, select Inbound Routes
- Add a new route or edit an existing one
- Enter a tag in the Shared Calls Tag field (you will use this tag when you set up SCA buttons on the phones). In this example we are using the tag 'sales' .
- Set Destination to the Ring Group created in Step One.
- Press the Submit Changes button
Step Three: Create an Outbound Route
To add an outbound route, perform the following steps:
- Open the UCX Web-based Configuration Utility
- From the PBX tab, select PBX Configuration
- From the left side column under Outbound Call Control, select Outbound Routes
- Add a new route or edit an existing one
- Enter the same tag used in Step One in the Shared Calls Tag field (e.g. sales)
- Press the Submit Changes button
Step Four: Configure Programmable Keys on XSTIM Devices
To configure an extension for a XSTIM phone, perform the following steps:
- Open the UCX Web-based Configuration Utility
- From the PBX tab, select PBX Configuration
- From the left side column under Basic, select XSTIM Phones
- All the configured XSTIM phones will be listed on the right hand side
- Select one of the XSTIM phones that you assigned to the Ring Group in Step One
- Scroll down to the section labelled Programmable Keys
- In the Label field of a shared call appearance key, enter a descriptive label such as "Line 1" or "Call 1".
- In the Digits field, the value MUST start with the letters "SCA" followed by a colon ":", a call number (1,2,3,...), the "@" sign, followed with the Shared Calls Tag (e.g. sales), and optionally end with ":N" to indicate that the call is presented to the key but does not ring.
- Press the Submit Changes button and apply your configuration changes (the dropdown selection box will automatically change to Other when you click the Submit Changes button).
