  1. Media Latchingdraft-kaplan-mmusic-latching • Documents Media Latching • Informational • Meant to provide a ref for latching (and HNT) • Documentcommon practice • Please review!

  2. Signalling • Latching: Not a SIP exclusive • XEP-0177 • A SIP and XMPP example SIP / XMPP UA NAT SBC / XMPP Server . . . c=10.1.1.1/12345 RTP sent to 10.1.1.1/12345 latch to source

  3. Security Considerations • Resource exhaustion • prob: attacker could flood all relay ports to prevent calls from succeeding • sol: Restricted Latching i.e. assert Signalling.IP == RTP.IP • Eavesdropping • prob: attacked floods in the hope of being latched upon • sol: restricted latching • prob: attacker spoofs IP or shares NAT with UA • sol: use SRTP

  4. Question Interest in adopting this as a WG document?
