Premium Voicemail
Premium Voicemail creates mailbox-based voicemail for selected phone numbers. It supports custom greetings, email and SMS alerts, transcription, retention controls, webhooks, inbox playback, and usage reporting.
Premium Recording Box
Premium Recording Boxes record inbound calls, optionally play a greeting, and then forward the call to another destination. They are useful when calls need to be captured for review, compliance, training, or follow-up.
Premium IVR
Premium IVR lets callers press keypad digits to navigate menus and route themselves to the correct destination. It supports multi-level menus, audio prompts, business schedules, holiday overrides, alerts, webhooks, and Number Manager routing.
Premium Announcements
Premium Announcements play an uploaded audio message to callers, then either hang up or forward the call to another destination. They support optional weekday schedules, holiday overrides, call history, and usage reporting.
Premium Time Conditions
Premium Time Conditions route inbound calls based on the date, day of week, time of day, and holiday overrides. They are most commonly used for business hours, after-hours routing, public holidays, and temporary closures.
