Abstract
A VoIP device stores a first set of VoIP parameters downloaded from a VoIP network to support call signaling associated with a primary user. The primary user enables a guest set-up mode by storing a guest access code to be associated with the guest user. The guest user enters a code on the VoIP device which the VoIP device compares to the stored guest access code and activates a guest profile if a match is detected. A second set of VoIP parameters is downloaded from the VoIP network and stored as part of the guest profile on the VoIP device to support call signaling associated with the guest user. SIP signaling is initiated between the VoIP device and the VoIP network including the directory number of the guest user, whereby the directory number of the guest user is mapped by the VoIP network to the VoIP device of the primary user. When the primary user initiates a call from the VoIP device, then the call is initiated using the first set of VoIP parameters. When the guest user initiates a call from the VoIP device, then the call is initiated using the second set of VoIP parameters.
