Patent ID: 7274662

Claim:
A method comprising reserving, for a particular call, packet network resources of a first packet network according to its own reservation policy; and reserving, for the call, packet network resources of a second packet network according to its own reservation policy, the second packet network being coupled to the first packet network and the reservation policy for the first packet network differing from the reservation policy for the second packet network, the reserving packet network resources of the first packet network being based on an indication from a calling party; the reserving packet network resources of the second packet network being based on an indication from a called party, the first packet network and the second packet network being coupled to each other through a third packet network, the indication from the calling party being a message indicating a limit for packet network resources of the first packet network to be reserved and for packet network resources of the third packet network to be reserved, the indication from the calling party being communicated to the third packet network via a first network edge device, and the indication from the called party being a message indicating a limit for packet network resources of the second packet network to be reserved and for packet network resources of the third packet network to be reserved, the indication from the called party being communicated to the third packet network via a second network edge device without being communicated via the first network edge device and the indication from the called party being communicated independently of the indication communicated by the calling party.
