PBX configuration

• Open the terminal from WMS and edit the call file template config located in the file /var/lib/callweaver/dialplan/alarm.template. 

Follow the prompts in the template to edit it:

# Call file template. Supported values (should be in {{}}):
# ID1, ID2 ... - RFPI Addresses, 10 hex digits, in descending signals level order, check it on the web interface of a base, Home/Status page
# SHORTID1, SHORTID2 ... - 2 last digits of IDs
# LEVEL1, LEVEL2 ... - corresponding signal levels, optional
# EXTENSION - extention of alarmed device
# NAME - user name of alarmed device
# TYPE - type of alarm, one decimal digit, check it on the web interface of a base, Alarm page, Idx column
Channel: Local/alarms@alarm-wair
Callerid: "{{NAME}}" <{{EXTENSION}}>
WaitTime: 60
MaxRetries: 3
RetryTime: 30
Context: alarm-wair, specify Dialpan procedure used for managing W-AIR calls here
Extension: {{SHORTID1}}{{TYPE}}
Priority: 1
Setvar: base={{ID1}}

...

• Start W-AIR alarms service on the PBX and enable it permanently:

  Code Block
  # systemctl start wairmsg # systemctl enable wairmsg

  
  

Dialplan configuration

Add the new Dialplan context "alarm-wair". This is the default Dialplan specified in the template file, use this name if you haven't changed it. 

In this "alarm-wair" dialplan add the following called numbers:

• alarms: (this called number is used by default in the template) under this called number specify where the alarm should be routed (e.g. use the Dialplan application Dial the phone or Call group)
• XXX: (e.g. 00X, 04X) specify your base stations' RPNs as called numbers in the format XXX, where the first two digits correspond to the RPN of the base station, the last digit can be used to specify the alarm type. 

...

Here is an example of how you can specify called numbers:

In this example:

• 000 and 004 are called in case the handset is located close to the base station with RPN 00:
  • 000 - in case it is a Man Down alarm,
  • 004 - in case it is a Red Button alarm.

...

For each XXX called number, you can use Dialplan application Play sound and specify the phrases that should be pronounced using the TTS service. For example:

In this example the following phrases are used:

Notes for Cloud PBX

To set up the feature on Cloud PBX, you need to:

• establish WMS Network between Cloud PBX and Virtual/ Hardware PBX 
• provision W-AIR Bases on Cloud PBX and set up W-AIR Network
• assign a user from Cloud PBX to W-AIR Headset (this user will trigger an alarm)
• assign a user from VM/ HW PBX to any device (this user will receive an emergency call)
• configure Alarm and Text Messaging & Alarm Server on Main W-AIR Base using VM/ HW PBX IP
• run PBX configuration and create Dialplan on VM/ HW PBX IP
