Voice over IP

I wonder how noisy the results would be if you tried VoIP Over [[WiFi]]? Going to try with Nokia N810.

Gizmo is Open Standards-supporting.

To prevent the above security concerns government and military organizations are using voice over secure IP (VoSIP), secure voice over IP (SVoIP), and secure voice over secure IP (SVoSIP) to protect confidential and classified VoIP communications.[37] Secure voice over secure IP is accomplished by encrypting VoIP with protocols such as SRTP or ZRTP. Secure voice over IP is accomplished by using Type 1 encryption on a classified network, like SIPRNet.[38][39][40][41][42] Public Secure VoIP is also available with free GNU programs and in many popular commercial VoIP programs via libraries such as ZRTP. http://en.wikipedia.org/wiki/Voice_over_IP#Securing_VoIP


I just attended a lecture from one of the big VoIP vendors. Apparently quality is dependent on the infrastructure: older 10Base-T might not cut it, newer networks do. But the cost savings isn't in the "free" long distance, it's in the applications, like receiving vmail in your email and vice versa, and combining your laptop with a soft phone, doing away with a mobile phone, etc. - Victor Lombardi

  • I'm not sure I agree about that much bandwidth being necessary (though of course a big question is how saturated your 10bT network is already). There are even people talking about VoIP over WiFi (although availability is still a big issue there). --BillSeitz

The voice folks have a different standard for what is "necessary" than data folks, i.e. "five nines" (99.999%) uptime, as reliable as your dial tone. - Victor Lombardi
