Hello, I have tried to use Zoiper as the standard program for url:sip protocol.
But when I go to my standard programs, I cant use Zoiper as standard for url:sip protocols.?
It happend when I was upgrading to Windows 10 from Windows 7.
Hello, are you using zoiper 3 Biz or Zoiper 3 Free?
Open settings -> preferences -> Automation -> General and click Manage protocol associations.
