Abstract
Systems and methods for adapting traditional landline telephones to make and receive Voice over Internet Protocol (VoIP) calls and other communications are described. In some embodiments, an adapter, adaptor, or other device or apparatus connects an IP router, such as a WiFi router or other access point, to a traditional landline telephone (e.g., a phone using dual-tone multi-frequency, or DTMF, signaling), enabling the traditional landline phone to make and/or receive VoIP calls.
Claims20
An adapter, comprising:
- a system contained within the adapter and configured for providing voice over internet protocol (VoIP) communication services to a publicly-switched telephone network (PSTN) phone connected to the adapter, the system comprising:
- a network communications module that manages communications between the adapter and an IP multimedia system (IMS) network;
- and
- a phone communications module that translates communications between the connected PSTN phone and the adapter.
A method for providing E911 services to a publicly-switched telephone network (PSTN) phone, the method comprising:
- determining that a PSTN phone is connected to a voice over internet protocol (VoIP) adapter,
- wherein the adapter is configured to translate communications between the PSTN phone and an IP Multimedia System (IMS) network accessed by the adapter;
- identifying an IP address for an access point (AP) via which the adapter is configured to access the IMS network;
- determining a user of the PSTN phone is at a geographical location associated with the identified IP address;
- and
- enabling E911 communications for the PSTN phone over the IMS network via the adapter based on the determined geographical location for the user.
An apparatus for providing a connection between a landline telephone and an IP Multimedia Subsystem (IMS) network, the apparatus comprising:
- a network communications circuit configured to manage communications to and from an IP multimedia system (IMS) network;
- and
- a phone communications circuit, coupled to the network communications circuit, wherein the phone communications circuit is configured to manage communications to and from a publicly-switched telephone network (PSTN) phone,
- wherein network communications circuit and the phone communications circuit together provide voice over internet protocol (VoIP) communication services to a user of the PSTN phone, via the IMS network.
