Connect and Disconnect Scripts

ASL3 supports a method to run a script or program when there is a node connecting or disconnecting.

This is handled by the connpgm and discpgm directives in rpt.conf.

Every Connect/Disconnect

Think your project through as this will run on every connect or disconnect. There is no way to limit it. However, your script could have a provision to ignore certain nodes or certain times.

Each node requiring this can have its own in that node's stanza. See Asterisk Templates for more information on how to apply this to individual node templates.

There is no requirement for using both connpgm and discpgm. Use the one you need, or both.

Shell scripts need to be readable and executable by asterisk. See the Permissions page for more information.

connpgm

connpgm executes a program or script you specify on connect.

An example to log connections to the node (conlog.sh):

#!/bin/bash

echo $1 connected $2  on $(date +"%T") - $(date +"%m-%d-%Y")  >> /var/www/html/nodelogs/conlog.txt

Example configuration in rpt.conf:

connpgm = /etc/asterisk/custom/conlog.sh

discpgm

discpgm executes a program or script you specify on disconnect.

An example to log disconnects from the node (dislog.sh):

#!/bin/bash

echo $1 disconnected $2  on $(date +"%T") - $(date +"%m-%d-%Y")  >> /var/www/html/nodelogs/conlog.txt

Example configuration in rpt.conf:

discpgm = /etc/asterisk/custom/dislog.sh

Execution and Passing Variables

Asterisk uses bash -c <connpgm-string> <us> <them> & when it runs connpgm and discpgm. Using the -c option means that commands are read from the string (script) specified. If there are arguments after the string (script), they are assigned to the positional parameters, starting with $0 (search the Internet for "Bash positional arguments").

As noted above, app_rpt adds two additional variables to the end of the command string being executed, <node number in this stanza> (us) and <node number being connected to us> (them). You don't NEED to use these variables, but they are provided for your use if your script wants to do something with them.

This also means you can pass variables/arguments to your script(s), if desired.

Sample:

connpgm=/etc/asterisk/custom/myscript abc 1234

The above example would then execute bash -c /etc/asterisk/custom/myscript abc 1234 <us> <them> when a node connects.
