1. A system comprising:
- one or more processors; and
hardware storing software that is executable by the one or more processors to perform operations including;
receiving a call request from a user device at a packet switched telephony service provider (PTSP), the call request including a telephone number corresponding to a public-switched telephone network (PSTN) subscriber;
transmitting the call request to a gateway for forwarding to the PSTN subscriber;
causing media data for a call between the user device and the PSTN subscriber to be routed between the user device and the gateway via a first communication channel; and
causing control data for the call to be routed via a second communication channel different than the first communication channel, the control data including ping data for the call sent while the call is in progress, the ping data comprising one or more signal strength indicators.

Abstract
A system and method for providing packet-switched telephony service. The system provides call control, signaling, and/or delivery of voice, video, and other media in substantially real time. One embodiment of the system includes a call client application on a user device, and a call server located at a packet-switched telephony service provider. The call server is preferably operable to communicate with the call client in a non-native protocol and with the gateway in a native protocol.

15. A method comprising:
-
receiving a call request from a user device at a packet switched telephony service provider (PTSP), the call request including a telephone number corresponding to a public-switched telephone network (PSTN) subscriber; determining an authorization status of the call request; transmitting the call request from the PTSP to a gateway for forwarding to the PSTN subscriber; causing media data for a call between the user device and the PSTN subscriber to be routed between the user device and the gateway via a first communication channel; and causing call control data for the call to be routed between the user device and the PTSP via a second communication channel different than the first communication channel, the call control data including call ping data sent while the call is in progress, the ping data comprising one or more signal strength indicators. - View Dependent Claims (16, 17, 18, 19, 20)
