Redundant AlphaCom integration

This article explains how to setup and configure redundant AlphaCom integration on an Exigo A-B system.
The solution may also be used for Exigo system with hot-standby controller.

Configuration Overview

Exigo Management Tool (EMT) is used for setting up the integration from Exigo.

EMT

AlphaPro is used for setting up the integration from AlphaCom.

AlphaPro

From Exigo there is two types of actions defined:

• Action Calls - from AlphaCom to Exigo.
• AlphaCom features - from Exigo to AlphaCom.

Exigo will use numbers from 98001 to 98099 to start activities in Exigo on incoming activities.
Outgoing from Exigo can define any number.

AlphaPro Configuration

Configuration on the AlphaCom with redundant call to Exigo contains three steps:

• Define and map IP addresses to the two Exigo Nodes (Controller A and Controller B).
• Defining Directory Numbers.
• Make a Group Call that calls both controllers.

Step 1. Define and map IP addresses to the first Exigo Node (Controller A)

The following steps needs to be repeated for Controller B.
Select Create Exchange to create the first Exigo SIP node in your AlphaCom system:

AlphaPro - Create exchange

Set the IP adress for the first Exigo PSC (Controller A) as the SIP Trunk Line:

AlphaPro - Set the Exigo PSC IP address as the SIP Trunk Line

Set up Net Routing:
Go to Exchange & System -> Net Routing:

AlphaPro - Setup the Net Routing

Select Insert:
Select the Exigo node:

AlphaPro - Setup the Net Routing

Select ACDP Link: SIP Link (31)

AlphaPro - Setup the Net Routing

Press OK. The steps above must then be repeated for Controller B.

After adding both controllers you should now have two Exigo nodes:

Net Routing - both controllers

Step 2. Defining Directory Numbers

In order to achieve redundancy the AlphaCom needs to call both controllers at the same time.
The next step is to add the directory numbers which are used in Exigo. These numbers are from 98001 to 98099: Select Directory and Features:

AlphaPro - Directory and Features

Here you need to add the number of directory numbers/Action Calls you need.
For redundancy you need to add minimum two numbers (for example 98001 and 98002).
98001 will then call Controller A, and 98002 will call Controller B.
Add a directory number 98001 with feature number 9 (Call a User).

AlphaPro - Directory and Features

This will give you a number that are automatically in All Call 84, and can also be added to groups.
Give the Directory Number a descriptive text in Display Text.
The User will look like this:

AlphaPro - User

Check the SIP Station box.
The Related to Trunk must be set to the correct Exigo SIP Trunk (one for each Exigo Controller).
For redundancy you need two numbers.
For example will 98001 call Controller A (node 2), and 98002 Controller B (node 3):

98001 - Node 3 (Controller 2)

Step 3. Group Call

In order to achieve redundancy AlphaCom needs to call both Exigo Controllers at the same time.
This is done by doing a Group Call from AlphaCom.
Go to Groups -> Local Groups. Edit (change) an available group and include the two member (for example 98001 and 98002):

Group Call - Calling both Controllers

This Group Call will then make sure that AlphaCom call both Exigo Controllers simultaneously.

Availability

This feature is available from Exigo 1.3.2.7 and newer.
