By default Zoiper automatically goes to sleep after 300 seconds of inactivity. This can cause an issue if you walk away from your desk as Zoiper may not ring.
Here we can change the timeout to 1 hour (3600 seconds).
Before making the changes. Please make sure Zoiper is closed down.
In the Windows search bar at the bottom type %appdata% and hit the enter key
This should open the Appdata/Roaming folder on your pc.
Now open the zipper folder
We need to edit the Config.xml file
Right click and choose Open With and then Notepad
We are looking for <auto_away>180</auto_away> near the top of the document, Change the 180 to 3600
Now choose File and Save
You can now open Zoiper again
