Upgrading/Downgrading Asterisk

This page reorganizes the operational steps for Upgrading/Downgrading Asterisk.
Upgrading or downgrading Asterisk should be done only if really needed. Asterisk relies on a series of libraries and different Asterisk versions may need different library versions.
A simple script to upgrade Asterisk is provided as protected/installAsterisk.sh
To upgrade to latest version 20, you can just run
cp protected/installAsterisk.sh /usr/local/src
cd /usr/local/src
./installAsterisk 20-current
If you want to upgrade to a specific asterisk version, you can provide it as
./installAsterisk 20.12.0
Current Verification
After applying the change, verify the related MiRTA PBX page, the Asterisk logs, and the relevant Status menu entry. Recheck tenant selection before testing tenant-specific behavior.
