  • Ticket #600 – Description

    v1 v2  
    66 1. UAC sent INVITE, and the INVITE forks to more than one UAS's, and the UAS's all send RTP to the UAC. In this case, it is expected that only RTP packets from one UAS will be successfully processed. 
    77 1. The SRTP keys have changed in re-INVITE/UPDATE, and the SRTP session has been re-created with the new keys, but some old RTP packets are still lingering in the network or in socket buffer. The SRTP then may learn it's initial state from these old packets. The old packets may have different properties than the new packets, e.g. SSRC or sequence number, and this will cause the new RTP packets to be rejected by the SRTP session.
