  12. Security and NAT traversal • SIP aware NAT/Firewall/ADSL modem • Client implements SIP NAT traversal extensions and STUN • Need of media proxies to deal with symmetrical NATs • TURN like approach

  13. Incoming instant messages • Presence based routing • To PC if present • To Mobile if not present on PC

  14. QoS Experience • No problems experienced over Internet • Access link may be bottleneck • IP-IP calls better than PSTN! • 8 kHz voice bandwidth compared to PSTN 3 kHz

  15. Conclusion • It is not about fixed voice line replication • SIP will survive  • Works today • SIP Communication services makes sense to bundle with broadband Internet access • New revenue stream • Similar set up as email service for service provider • SIP voice not degraded by peer-peer movie congesters in networks without QoS • Gives mobility access to multimedia communication services similar to email access
