Abstract:
A telecommunications system includes a packet network (101); a plurality of VoIP endpoints (102); and a plurality of VoIP feature servers (104). The VoIP endpoints are able to send configuration request messages to the feature servers. The feature servers respond with information indicative of supported features. The VoIP endpoints can then update the system configurations based on the response information. Further, newly added feature servers transmit feature availability messages to endpoints when initially installed. The endpoints then respond to configure themselves appropriately.
Abstract:
A presence trigger system and a service system support automatic actions on a voice conference based on the presence state of potential conferees of the voice conference. The systems may, for example, initiate contacting and joining the potential conferee to the voice conference when the potential conferee presence state indicates that the potential conferee is available. As another example, the systems may automatically notify participating conferees that the potential conferee has become available. Automatic notification allows participating conferees to concentrate on and contribute to the voice conference without the distraction of frequently checking the presence status of expected, but absent, conferees.
