I regularly need to switch between PC and android clients registered on the same number. I have X-Lite installed on windows PC and Zoiper on Android. When I am back to my desk I just start x-lite and it connects straight and when I need my incoming call going to android I just close it. However it takes quite a while for android zoiper to start taking incoming calls. It's usually a few minutes during which all incoming call are rejected before it's back to normal. Is there a way to force zoiper to register for incoming calls straight away so there is no downtime?
