14. A method for synchronizing call-state information between two or more telephone switches involved in a multiparty communication session over a communications network including steps of:
-
(a) connecting each involved switch to a digital network; (b) establishing a call connection using the two or more switches between a first party and a second party; (c) establishing minimally one additional party by second call connection to define a multiparty session; (d) from the digital network side of each switch, monitoring the party information and call-state events of each party connected to each switch involved in the communications session; (e) causing propagation over the digital network from certain ones of the switches to other switches involved in the session, party-identity and call-state information as the information becomes available to the certain ones of the switches; and (f) causing notification to be sent to certain parties connected to the switches receiving the party identification and call-state information, the notifications containing the party identifiers and current call-states of the other parties. - View Dependent Claims (15, 16, 17, 18, 19, 20, 21, 22, 23, 24)
