Appendix I – IP-to-IP gateway scenarios
        I.1               Scenario 1: Same codec, same packet size, no jitter buffer
        I.2               Scenario 2: Same codec, same packet size, jitter buffer introduced to protect Network A from Network B's jitter
        I.3               Scenario 3: Same codec, different packet size
        I.4          Scenario 4: Different codec, different packet size
