RJ45 LAN Intranet Internet  Now we have a new global network: The IP Networks  And we have a new standard: SIP RJ11  POTS and PSTN have been there for 100 years Black Phone IP Phone PresenceMessaging Video Voice 3.5 kHz isn’t HiFi, but MOS is 5!

SIP General SIP Handling Required Especially when all the WiFi Mobile Phones Come IMS WiFi mobiles really become useful when:  SIP and Multimedia become available on the LAN  Workaround methods are not required  Reliability and battery life recovered No battery draining of WiFi mobile phones, otherwise caused by keep-alive packets* inhibiting sleep mode. * Work-around methods for SIP NAT-traversal like STUN, TURN, ICE and Far End NAT Traversal use frequent keep-alive packets to keep holes in the NAT/Firewall open.
