Patent ID: 7957373

Claim:
A communication system comprising: an application server including logic to receive corresponding preference data for each of a plurality of data record entries of a subscriber record from a telephone number mapping server and to determine a contact sequence including a plurality of uniform resource indicators, wherein each uniform resource indicator corresponds to one of the plurality of data record entries and each uniform resource indicator is associated with a corresponding destination device, wherein the contact sequence includes a temporal schedule that specifies a first time period between initiating a first invite message to a first uniform resource indicator and initiating a second invite message to a second uniform resource indicator, wherein the first time period is determined based on a difference between first preference data of a first data record entry associated with the first uniform resource indicator and second preference data of a second data record entry associated with the second uniform resource indicator, and wherein the second invite message is initiated conditioned on passage of the first time period following initiation of the first invite message, and wherein the contact sequence indicates a corresponding time period between initiation of an invite message to a particular uniform resource indicator in the contact sequence and an invite message to a next uniform resource indicator in the contact sequence, wherein a particular time period is determined based on a difference between the preference data of the data record entry associated with the particular uniform resource indicator and the preference data of the data record entry associated with the next uniform resource indicator, and wherein the invite message to the next uniform resource indicator is initiated conditioned on passage of the particular time period following initiation of the invite message to the particular uniform resource indicator.
