EasyRinger Pro subscriptions now set up their voicemail to convert voicemails to text and send an email containing the text. At the bottom of your “Voicemail Options” tab, you will see this checkbox:
Voicemail transcription is the conversion of the voicemail audio track into written words to be stored as plain text in a conversational language. Voicemail transcription can be a useful tool for business, training, medical, or legal reasons. Text has more advanced search and analysis features available than audio. A text-based history of voicemails is necessary for many use cases.
