Abstract: Methods, systems, and computer program products for E911 registration assistance for subscribers using portable Internet Protocol (IP) communications devices are disclosed. According to one method, an IP address of a portable IP communications device is stored. A message is received that indicates an IP address of the portable IP communications device. Next, it is determined whether a difference between the stored IP address and the received IP address indicated by the registration message indicates a change in geographic location of the portable IP communications device. In response to determining that the difference between the stored IP address and the IP address indicated by the received message indicates a change in geographic location of the portable IP communications device, a subscriber is prompted to update stored geographic location information for providing E911 service to the subscriber.

Abstract: Methods, systems, and computer program products for using a personal conference to privately establish and control media connections with a telephony device are disclosed. According to one method, a media connection is established between a first user and a personal conference instance. The first user is connected to the personal conference instance via a telephony device, such as a PSTN phone. A plurality of second media connections is established between a plurality of second users and the personal conference instance in a manner that conceals existence of the personal conference instance to at least one of the second users. Media packets from the second users are mixed and sent to the first user. Media packets from the first user are sent to the second users. The first user dynamically controls at least one aspect of the personal conference call instance.

Abstract: Methods, systems, and computer program products for automatically establishing a conference call having a plurality of different subscriber participation classes includes maintaining at least one per conference call subscriber participation class list. The per conference call subscriber participation class list indicates contact information for a plurality of different subscribers and corresponding subscriber participation classes for the conference call. When a conference call is initiated, the call is automatically established using the contact information and the subscriber participation classes stored in the per conference call subscriber participation class list.
