How to get location of W-AIR Base Station in case of emergency alarm triggered

Requirements

• Hardware/ Virtual PBX
• W-AIR Network 
• W-AIR firmware v. 0501b5

W-AIR configuration

1. Go to the web interface of the Primary W-AIR Base Station -> Management
2. Enable Tex Messaging 
3. Set PBX as Text Messaging & Alarm Server
4. Change Text Messaging Port to 9300 

• Reboot the W-AIR base

PBX configuration

• Edit call file template config located in the file /var/lib/callweaver/dialplan/alarm.template:

# Call file template. Supported values (should be in {{}}):
# ID1, ID2 ... - RFPI Addresses, 10 hex digits, in descending signals level order
# SHORTID1, SHORTID2 ... - 2 last digits of IDs
# LEVEL1, LEVEL2 ... - corresponding signal levels
# EXTENSION - extention of alarmed device
# NAME - user name of alarmed device
# TYPE - type of alarm, one decimal digit
Channel: Local/alarms@alarm-wair
Callerid: "{{NAME}}" <{{EXTENSION}}>
WaitTime: 60
MaxRetries: 3
RetryTime: 30
Context: alarm-wair
Extension: {{SHORTID1}}{{TYPE}}
Priority: 1
Setvar: base={{ID1}}

• Edit Dialpan procedure used for managing W-AIR calls. For example:

1. Custom application -> Set(WAIR_mac_address=${SIPCHANINFO(useragent):-27:12})
2. Custom application -> Dial(SIP/100&SIP/300,30,A(00000/wair_${WAIR_mac_address}&00000/call_from_ext_${CALLERID(num)}))

where

• SIP/100&SIP/300 - extension of Calls groups
• 30 - indicates call timeout (in seconds, can be customized)
• $ {WAIR_mac_address} - returns the mac address of the Base on which the handset is registered
• $ {CALLERID (num)}  - returns the extension number of the caller
• 00000 / wair _ $ {WAIR_mac_address} and 00000 / call_from_ext _ $ {CALLERID (num)} - indicate paths to recorded audio files

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

  # systemctl start wairmsg
  # systemctl enable wairmsg
