asterisk_reconnect is a tool to periodically check that a list of clients are connected to Asterisk, and if they are not connected it will attempt to reconnect them and drop them into the specified context and extension.
- Periodically checks which clients are connected to Asterisk via the AMI.
- If a client is not connected, asterisk_reconnect will attempt to reconnect.
- Check intervals, retry intervals and clients, contexts and extensions are fully customisable.
- Works with SIP Clients. Other channel types are untested.
- asterisk_reconnect is designed for python 3 only!
- To date, this has only been tested on a Debian based, AllStar Asterisk (1.8) system
- It's important you secure your .cfg file, as anyone with access to the configuration can dial any client (Fraud Risk)
Change to root:
sudo su
cd /opt/
git clone https://github.com/marrold/asterisk_reconnect.git
Change into the directory:
cd asterisk_reconnect
Install requirements:
pip3 install -r requirements.txt
Copy/Rename the sample configuration:
cp asterisk_reconnect-sample.cfg asterisk_reconnect.cfg
Edit the defaults, use the comments as a guide:
vim asterisk_reconnect.cfg
Check it runs:
python3 asterisk_reconnect.py
In order for Asterisk to mark calls as down, it needs a method of detecting lack of activity on a channel. Theres two methods documented below.
In order for this to work your 'client' will need to always send RTP, even when silent / muted / on hold etc:
Open sip.conf for editing
vim /etc/asterisk/sip.conf
Add the following in the [general] section:
rtptimeout=60
If you're application intentionally stops sending RTP occasionally , you can enable session-timers to detect when a call drops. This will require a client with RFC4028 support, and detecting a dropped call will potentially take longer than the rtptimeout method.
Open sip.conf for editing
vim /etc/asterisk/sip.conf
Add the following in the [general] section:
session-timers=originate
session-expires=300
session-minse=90
session-refresher=uac
The following assumes you're using a systemd based OS such as Debian 9.
Create a systemd service file:
vim /lib/systemd/system/asterisk_reconnect.service
Enter the following:
[Unit]
Description=asterisk_reconnect service
After=syslog.target network.target
[Service]
User=root
WorkingDirectory=/opt/asterisk_reconnect
ExecStart=/usr/bin/python3 /opt/asterisk_reconnect/asterisk_reconnect.py
[Install]
WantedBy=multi-user.target
Make it executable:
chmod 755 /lib/systemd/system/asterisk_reconnect.service
Reload the systemctl daemon:
systemctl daemon-reload
Enable the service:
systemctl enable asterisk_reconnect.service
