It is up to you after how many rings you would want an incoming call on your Spectrum Home Phone to go to the Spectrum Voicemail. By default, it is diverted to voicemail after 5 rings. If you want to change this, sign in to your Spectrum account. Go to the phone icon, which will get you to the Voice Online Manager. Look for Settings. And then select the Number of Rings. Pick your number from 3-6. And then save changes.
