Abstract
A hybrid cordless telephone system allows a user to place or receive a call over either a data network or a PSTN network. In one aspect, a system router and PSTN unit are coupled with a communications manager to avoid extensive redesign of router components and PSTN components while providing a wireless user with data network and PSTN connectivity. In another aspect, the system router of the hybrid cordless telephone system includes a communications manager configured to provide termination of data network calls or PSTN calls at the system router. Accordingly, a plurality of handsets can each access the system router to place or receive calls from the data or PSTN networks.
