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

The present invention is directed to a system and method for implementing an intelligent redial system. A method for storing redial data for a connection between a user phone system and a remote phone system may include establishing a connection with the remote phone system by the user phone system. A timer is started in response to the established connection. At least one digit is dialed by a user and corresponding time data of the timer with the dialed digit is monitored. The monitored digit and corresponding time data is stored. The stored monitored digit and corresponding time data are suitable for performing a redial.

Method and system for implementing an intelligent redial system

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.

Methods and apparatus for facilitating remote communication with an IP network

A telecommunications system includes a network (); a plurality of endpoints () operably coupled to the network; a gatekeeper and a database engine, typically located in a gatekeeper server (), for downloading database information such as a corporate directory, to the endpoints. The gatekeeper server and the endpoints further include load monitors () for monitoring device performance. If the load is higher than a threshold, the gatekeeper will not provide a requested database information. The endpoint then requests the information from another endpoint.

Self managing directory service for voice over IP networks

A gatekeeper () including a compare unit () and a record unit (). The compare unit () receives call requests and accesses a database which is a record of where a called party picked up the call, e.g., at home, at the office, via a mobile phone, or via an emergency number. The compare unit () performs an analysis such as a 'closest neighbor' analysis to determine the location of the user at the time of day closest to that of the present call. The call is then routed to the user at that location. The record unit () then makes the appropriate notation in the database for the latest call.
