Mobile VoIP / VoIP over a 3G network
Hi All !
Tonight, I thought a little bit about the interest of a VoIP call over EDGE / 3G mobile network. According to my test, one of the best way to do that is to use tivi program (www.tivi.com). But, thinking about cost, it doesn't seem to be a good deal. read this exemple :
the GSM codec is around 13kbit/s bandwith. So, a 1min call needs around 100ko (13*60/8). Okay, silence are reduced to zero, but voice is on two ways ;). And how much is 100ko? Take the French exemple. My mobile provider is Orange. If I go to Russia, I will be charged 0,13euros for 10ko. So, 1min will be around 1,30 euros + fees from VoIP provider. If I use EQO or VYKE call back system, I will be charged inbound call (around 0,5euros), plus EQO fees ....and it is really cheaper ;).
You can think that the tivi application use a low quality GSM codec, so 5kbit/s, but noone knows. Plus, it isn't written on tivi website.
So, use EQO - like systems to give a call, if you don't have a wifi access ;) (and a cell phone with this feature).
Enjoy travelling ;)
