VoIP adapter for connecting landline phones to IP routers
View Patent ↗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.
1. 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.
2. The apparatus of claim 1 , wherein
the landline telephone communications module manages communications between the IMS network and a publicly-switched telephone network (PSTN) telephone.
3. The apparatus of claim 1 , wherein
the landline telephone communications module receives tones input by a publicly-switched telephone network (PSTN) telephone connected to the apparatus via the RJ-11 connector and translates the received tones into instructions to be provided to the IMS network via the IMS module.
4. The apparatus of claim 1 , further comprising:
a universal serial bus (USB) connector configured to connect the apparatus to the access point to provide power to the apparatus via the access point.
5. The apparatus of claim 1 , wherein the wireless connection component is an Ethernet connector configured to connect the apparatus to the access point.
6. The apparatus of claim 1 , wherein the subscriber identity module (SIM) card facilitates remote management services of the apparatus by a telecommunications carrier that provides the IMS network and that includes a user of the apparatus as a subscriber of the IMS network.
7. The apparatus of claim 1 , further comprising:
a USB connector configured to connect the apparatus to a USB port of a wireless router.
8. 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.
9. The system of claim 8 , wherein the landline telephone communications module manages communications between the IMS network and a publicly-switched telephone network (PSTN) telephone.
10. The system of claim 1 , wherein the landline telephone communications module receives tones input by a publicly-switched telephone network (PSTN) telephone connected to the apparatus via the RJ-11 connector and translates the received tones into instructions to be provided to the IMS network via the IMS module.
