The CapTel 200 is designed to work with a standard analog telephone line, the type of line most commonly found for household telephones.
- It also can be used with a Digital Subscriber Line (DSL) with a DLS filter.
- CapTel 200 is not compatible with VOIP or digital cable telephone services. VOIP users should use the Internet-based CapTel instead.
- Connection to any telephone line other than analog may damage the CapTel 200 or the telephone system, and will void the CapTel 200 warranty. Exception: Using CapTel 200 in 2-Line mode as directed below.
