| Isn't It Impractical Right Now?
While technically possible, I thought it's unable to work well right now. Why?
VOIP uses the Internet right? So, to have a VOIP client on a mobile, you need to use mobile phone Internet.
Problem is, while transfer rates are sufficient even on EDGE, latencies are horrible, even on 3G. Too much delay for voice, and it can make conversations difficult.
I looked into this myself, when I explored the idea of having a mobile phone as an extension for an Asterisk PBX, and running a SIP client on the mobile.
So why it can't work:
- The SIP client will need a beefy device, so a smart-phone is a requirement. Smart-phones are at a price point that turns off most people.
- The Mobile Internet isn't fast enough. Specifically, the latencies are horrible. It's not as bad as satellite, but it's still bad.
Maybe later, when Mobile Internet gets better latencies, those willing to spend the money on smart-phones can try this. | |

Correct. That's why the iSkoot solution does not involve VoIP from the handset. with iSkoot the handset uses a data connection only to do call setup with an iSkoot server, the handset then calls, using a voice circuit, the gateway number for the iSkoot service, the iSkoot server VoIPs the call to Skype and does the handshake with the Skype server. No QoS problems (other than the ones you normally experience on your cell phone, the carrier is kept (reasonably) happy as you are still using minutes and you save on all international calls. Downside, you don't save on "in minutes" calls since you are still making them, you need a supported handset, although all Java should work, they don't and incoming calls work less well (the app needs to be running).
Happy iSkoot user till I changed phones and lost support. | |
