Abstract
Techniques for connectivity using a geographic phone number are described. According to various implementations, techniques described herein enable various policies pertaining to the use of telephone numbers at different locations to be enforced. For instance, techniques described herein enable a client device that is outside of a permitted geographic area for a geographic phone number to use a non-geographic phone number to connect a call, while the call can be routed using the geographic phone number.
Claims20
A method comprising:
- establishing a first session portion using Internet Protocol (IP) communication between a calling device and a communications service;
- establishing a second session portion using IP communication between the communications service and a PSTN switch, the second session portion addressed via a non-geographic number of the calling device;
- establishing a third session portion using PSTN communication and a geographic number of the calling device between a PSTN switch and a callee device;
- and
- establishing a call between the calling device and the callee device via the first session portion, second session portion, and third session portion.
A system, comprising:
- hardware processing circuitry;
- one or more hardware memories storing instructions that when executed configure the hardware processing circuitry to perform operations comprising:
- establishing a first session portion using Internet Protocol (IP) communication between a calling device and a communications service;
- establishing a second session portion using IP communication between the communications service and a PSTN switch, the second session portion addressed via a non-geographic number of the calling device;
- establishing a third session portion using PSTN communication and a geographic number of the calling device between a PSTN switch and a callee device;
- and
- establishing a call between the calling device and the callee device via the first session portion, second session portion, and third session portion.
A computer readable medium comprising instructions that when executed configure hardware processing circuitry to perform operations comprising:
- establishing a first session portion using Internet Protocol (IP) communication between a calling device and a communications service;
- establishing a second session portion using IP communication between the communications service and a PSTN switch, the second session portion addressed via a non-geographic number of the calling device;
- establishing a third session portion using PSTN communication and a geographic number of the calling device between a PSTN switch and a callee device;
- and
- establishing a call between the calling device and the callee device via the first session portion, second session portion, and third session portion.
