Configure VoIP account
When you first open the app, you need to configure an account with a Voice over IP provider. If you don’t have one, you need to go to a provider’s website and sign up, e.g.:
- https://www.callcentric.com
- https://www.voip.ms
-
https://sonetel.com
These offer cheap rates and a wide array of phone numbers.
Configure recording
Once you have your account configured in Groundwire or Acrobits Softphone, go to 
Keypad > 
> Preferences > Call Recording and turn on Multichannel
Transfer recordings
You can configure to have your recordings sent to your email, but if the files get big, you can also access them from the 
History tab. You’ll see a little answering machine symbol on the left, if the call has a recording. You can access it by clicking on the 
on the right.
Clicking on the next to the recording again gives you sharing options like AirDrop on iOS. Note: Behind the AirDrop option you’ll find much more than just AirDrop. You’ll get the standard sharing options including saving the file to iCloud or other file sharing services.
