Revert back to v15.5 on Debian 9

[D3NN3]

Hello,

Yesterday v16 was automatically installed, which caused this morning that our call flows disappeared (not good!).
We want to reverse to version 15.5 so we can restore our backup with the working call flows.

How can I install v15.5 of 3CX with the following commands on Debian 9 (via OVH)?

wget -O- http://downloads-global.3cx.com/downloads/3cxpbx/public.key | sudo apt-key add -
echo "deb http://downloads-global.3cx.com/downloads/debian stretch main" | sudo tee /etc/apt/sources.list.d/3cxpbx.list
sudo apt update
sudo apt install net-tools
sudo apt-get install 3cxpbx


Thank you!

Best regards,

Dein Dehouwer

Thank you! That was the right track. For correct reference the following command is what finally worked:

apt-get install 3cxpbx=15.5.15502.6

Make sure to first remove the current version with the following:

apt-get remove --purge 3cxpbx

Follow this. Backup first.
