Systems and methods of providing communications services

A system for providing communications services, comprising:

• means for receiving a request for communications services from a first telephony device that is native to a first telephony system that provides cellular based telephony services, wherein the receiving means is part of a second telephony system that provides landline type telephony services;
• means for determining whether the first telephony device is associated with the second telephony system based on settings of an existing account with the second telephony system, wherein the determining means obtains an identifier associated with the first telephony device from a software application running on the first telephony device, and wherein the determining means uses the identifier to determine whether the first telephony device is associated with an existing account within the second telephony system;
• and
• means for providing the requested communications services based on the result of the determining step.

A system for providing communications services, comprising:

• an extension connection unit that receives a request for communications services from a first telephony device that is native to a first telephony system that provides cellular based telephony services, wherein the extension connection unit is part of a second telephony system that provides landline type telephony services;
• an authorization unit that determines whether the first telephony device is associated with the second telephony system based on settings of an existing account with the second telephony system, wherein the authorizing unit obtains an identifier associated with the first telephony device from a software application running on the first telephony device, and wherein the authorization unit uses the identifier to determine whether the first telephony device is associated with an existing account within the second telephony system;
• and
• wherein the extension connection unit causes the requested communications services to be provided to the first telephony device through the second telephony system if the authorization unit determines that the first telephony device is associated with the second telephony system.

A method of providing communications services, comprising:

• receiving a request for communications services from a first telephony device that is native to a first telephony system that provides cellular based telephony services, the request being received at a second telephony system that provides landline type telephony services;
• determining whether the first telephony device is associated with the second telephony system based on settings of an existing account with the second telephony system;
• and
• providing the requested communications services based on the result of the determining step, wherein the providing step comprises sending a communication to a second telephony device, and wherein the communication includes an identifier associated with the first telephony device.
