Just to clarify, are you referring to using Jobber on a mobile device or on a desktop computer?
If it’s on mobile, which device are you using — iPhone or Android?
If you’re using an iPhone, you can go into your app settings and change the default calling app to RingCentral. Then when you tap a phone number inside the Jobber app, you can choose RingCentral to place the call instead of using your personal phone number.
Let me know what device you're using and how you normally access Jobber. I’d be happy to help you figure out the best setup.
Thanks!
