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.
Claims10
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;
- an IMS module, coupled among the RJ-11 connector, 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 connector and the IMS network,
- wherein the IMS module includes a session internet protocol (SIP) client that facilitates SIP communications between the apparatus and the IMS network and an internet protocol security (IPsec) client that provides a secure communication tunnel for the SIP communications between the apparatus and the IMS network;
- and
- a landline telephone communications module having a media gateway that translates communications between the IMS module of the apparatus and the landline telephone, including:
- translating SS7 protocol information received from the landline telephone connected to the apparatus via the RJ-11 connector into SIP protocol information actionable by the IMS module;
- and
- translating SIP protocol information received from the IMS module into SS7 protocol information actionable by the landline telephone.
A system, comprising:
- at least one hardware processor;
- at least one hardware memory coupled to the at least one hardware processor, wherein the at least one memory stores modules executed by the at least one hardware processor, wherein the modules include:
- an IMS module, coupled to a RJ-11 connection and a SIM card of an adapter, that manages communications between a landline telephone connected to the apparatus via the RJ-11 connection and an IP Multimedia Subsystem (IMS) network,
- wherein the IMS module includes a session internet protocol (SIP) client that facilitates SIP communications between the apparatus and the IMS network and an internet protocol security (IPsec) client that provides a secure communication tunnel for the SIP communications between the apparatus and the IMS network;
- and
- a landline telephone communications module having a media gateway that translates communications between the IMS module of the apparatus and the landline telephone, by:
- translating SS7 protocol information received from the landline telephone connected to the apparatus via the RJ-11 connector into SIP protocol information actionable by the IMS module;
- and
- translating SIP protocol information received from the IMS module into SS7 protocol information actionable by the landline telephone.
