2-Line CapTel is an optional way to use the CapTel 840 phone that is more convenient and transparent for you and your callers. By using two telephone lines instead of just one telephone line, your CapTel 840 can display captions on every call, at any point in the call. Your callers won’t need to dial the captioning service first for you to get captions.

CapTel offers 2-line telephone service for hearing loss.
