Zusammenfassung:A system and method for falling back to a secondary network when there is insufficient quality on a primary network is disclosed. The present invention uses a PSTN as a fallback for the IP media when the IP network cannot pass the media acceptably and while continuing to use the IP network for call control and other features. In one embodiment, a call manager has a media monitoring module, a bypass module, a PSTN control module and a GUI module. Once a call has been established between endpoints using a primary IP network, the media monitoring module monitors for degradation in call quality. If degradation in call quality is detected, the GUI module presents an interface to the user that allows selection of the secondary network or the primary IP network for continuation of the call. If the user selected the secondary network, the bypass module is activated to transfer the data communication to a secondary network such as a PSTN while the call control continues to be over the primary network. The present invention also includes a variety of methods including a method for falling back to a secondary network and a method for dynamically switching between a primary and a secondary network to ensure call quality.
