How to set up Groundwire for a Virtual Landline

We recommend that you use the Invoco Softphone over any other solution – which is included in the Essentials and Unlimited PBX packages. If you want to chat more about the Invoco Softphone, just drop us a message!

Groundwire is a softphone that acts as a suitable addition to our Yealink phones whilst you’re on the go.

Requirements

To set up Groundwire, you need either:

• A Virtual Landline, or

The only difference in setting up the app is how you obtain the login credentials.
