A user logs in, at a first address, using a first communication device and establishes communication with an associated server using a wireless communication link. The user enables the first user to log in, at a second address, using the first communication device and establish communication with an associated server. Another user can log in using one or more communication devices. User identifiers for a second user are displayed in a quick dial list for a first user. When the first user selects the second user's identifier, the second user's address information is obtained and used to establish communication between these users.
