True VoIP at 64Kbps !

After my initial success of VoIP and SIP on my N80 in the 128Kbps ADSL, i tried the same on my 64Kbps ADSL home connection. Same settings. I use the same name of my Office Accesspoint at my home also. Thanks to Truphone, I could test VoIP to some real telco numbers in the US for free. I couldn’t believe ! The call was indistinguishable as VoIP call to the persons at the  receiving end. No lag , echo or delay. I must say the call was better than the PSTN calls I do to my parents in India. Then I tried a pure VoIP to VoIP . Sharing the 64Kbps, I was able to get a perfect call to my computer. I had GizmoProject at my home pc and using my N80 I was able talk to my kids (Just for fun) I could better talk to them direct ! It’s really amazing ! I remember the ISDN people telling you must have 128Kbps for two-way communication ! But then , it was Fifteen years back !

Though we might feel great initially, later we feel like working in a Call Center and the enthusiasm dies. But yes, there are “hardware” USB “phones” […]
