Abstract:
In existing IP telephony RTP session table cannot be regenerated during failure. It requires periodic session mirroring. All calls established between mirroring are dropped during switchover. RTP session mirroring is not possible during software crash or manual software upgrade. In this invention all sessions are rebuild from incoming voice IP packets without having any knowledge of the lost RTP session table. To achieve this RTP server always assigns predetermined paired ports for each session. In the recovery phase the RTP session table is rebuilt mathematically from the very first incoming voice packet. So in the event of the active RTP server failure the standby RTP server resumes call sessions without interruption.

Claim (Index 1):
This invention enables RTP sessions to be mathematically rebuilt from incoming voice IP packets without having any prior knowledge of the RTP session.
