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 apparatus for connecting a landline telephone to an IP Multimedia Subsystem (IMS) network, the apparatus comprising:
- an RJ-11 connector;
- a wireless connection component that connects the apparatus to an access point associated with the IMS network;
- a subscriber identity module (SIM) card;
- and
- an IMS module, coupled among the RJ-11 connection, the wireless connection component and the SIM card, and configured to manage communications between a landline telephone connected to the apparatus via the RJ-11 connection component and the IMS network.
An adapter, comprising:
- a system contained within the adapter and configured for providing voice over internet protocol (VoIP) communication services to a publically-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 publically-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.
