A ToL client is provided having, e.g., a key or button for the user to press or click when a voice problem arises. A controller maintains a set of predetermined 'channels' having various voice quality settings, for example, related to codec selection, noise filters, jitter buffer size, echo cancellation, and the like. The user can select one of the channels and the connection will transfer over to using the parameters indicated. On subsequent uses, the new 'best' channel can be the default or first selected.

System and method for virtual channel selection in IP telephony systems

A system, method, apparatus, and computer program code for facilitating communication via an IP network. According to some embodiments of the present invention, a proxy device is positioned topologically between an IP enabled communication device (e.g., an IP telephone) and an IP based network. The proxy device may establish a remote access connection to the network before or after receiving a request from the IP enabled communication device to communicate to or via the network. The proxy device then facilitates communication between the IP enabled communication device and the network. In addition, the proxy device may modify source and/or destination IP addresses in messages or other communications received from the IP enabled communication device prior to sending such messages or other communications to the network and may modify source and/or destination IP addresses in messages or other communications received from the network prior to sending such messages or other communications to the IP enabled communication device.
