I sometimes need to disable my VoIP account in Zoiper so I can use it on the desktop.
There does not seem to be an easy way to do this. Unregistering does not help, somehow Zoiper keeps registering itself. Removing server names etc. is not accepted. I could intentionally enter wrong usernames or passwords, but that will get my IP banned.
I currently need to delete my account and create it again afterwards which is needless to say is a pain.
