Abstract
The present method provides for a session initiation protocol timing arrangement which facilitates instant communications in a packet data communication system (). Each network server (-) sets a time out timer () which is coordinated with each of the downstream network servers. Network server (), for example, sets a time out timer value which is selectable by the system operator. Subsequent network servers (and) then set the value of the time out timer to be that of the originating server () or client () less a fixed time such as one second. Further, a provisional message () is sent through the network to avoid expiration of the time out timer in upstream stages.
