SYSTEMS AND METHODS FOR CONNECTING TELEPHONY COMMUNICATIONS

摘要

Systems and methods performed by an IP telephony system are designed to determine when two parties to a recently terminated telephony communication are simultaneously calling each other in an attempt to re-establish a telephony communication. When the IP telephony system determines that this situation is occurring, the IP telephony system acts to connect the two parties, rather than have both of them see their new call setup attempt fail because the other party's telephony device is indicated to be busy.

主权项

1. A method performed by an Internet protocol (IP) telephony system for establishing a telephone communication between two parties, comprising:
receiving a telephony communication setup request from a first telephony device; attempting to setup the requested telephony communication to a second telephony device identified in the setup request; checking, if the second telephony device is presently unavailable, to determine if the second telephony device is attempting to setup a telephony communication to the first telephony device; and causing a telephony communication to be established between the first telephony device and the second telephony device if the result of the checking step indicates that the second telephony device is attempting to setup a telephony communication to the first telephony device.
