- US-only registered captioned-telephone service for users whose hearing loss makes telephone captions necessary. Spanish captions are documented; the developer does not publish a full list of recognition languages (English calls are the default context of all documentation but no language list is stated).
- Ongoing no-cost service only for qualified, registered US users with hearing loss that necessitates captioned telephone service (funded by the FCC-administered IP CTS fund).
- Users self-register and self-certify in the app; a separate optional professional referral route exists for providers.
- Via Picture-in-Picture mode during a call; "PiP mode availability depends on your device’s operating system and version."
- Only a font-size control is documented; other display controls were not found in official documentation.
- Sorenson-wide privacy policy covering CaptionCall, LLC services.
- Refers to the server-side processing copies held by Sorenson and its service providers. Call transcripts saved in the app History and voicemail messages are separate and not covered by this statement.
- Applies to voicemail messages; the app is not documented as recording calls.
- Call transcripts are stored in the History tab (see "Where do I find my call transcript?"); deletion is done from History.
- Sorenson-wide policy; in-app deletion is described as "if available", so contacting Sorenson is the documented route.
- Available where applicable US state privacy laws grant an access right; requests via privacy@sorenson.com, the Your Privacy Choices page or toll-free phone. Evidence: U.S. State Privacy Rights — Access.
- During an active call only; "PiP mode availability depends on your device’s operating system and version."
- Qualifying hearing loss and service eligibility are required.
- Calls to the assigned CaptionCall number are captioned; calls to the user’s existing mobile number are captioned only after call forwarding is set up (carrier must support forwarding).
- Forwarding from the user’s existing mobile number to the CaptionCall number depends on the mobile carrier plan supporting call forwarding; set up in-app, in device settings or via carrier star codes.
- Three-way calls (two other parties) are documented.
- Only for voicemail messages left for the user; no general record-then-transcribe workflow is documented.
- Microphone carries the user’s own side of the call, which the app can also caption ("Show my captions" setting).
