delete https://api.phone.com/v4/accounts//voicemail
Phone.com’s standard phone service allows callers to leave a voicemail if the incoming call was not answered. The /voicemail services show a history of voicemail and allow users to download voicemail for offline playback.
The endpoint .../voicemail (combined with the HTTP method DELETE) allows the user to delete one or more voicemail in one shot. Be careful when using this API and pass the correct Query Params as needed.
