How do I enable/disable sending my Grasshopper calls straight to voicemail?

Use the "Hold my calls" feature to send your calls straight to voicemail, instead of having them ring to your phone first (iOS app only). 

  1. Tap the Settings button in the top-left of the upper toolbar. 
  2. Tap Hold My Calls to toggle the setting on or off. 

Note that this feature is not yet available for the Android app.
