VoIP via mobile!! - help needed

redux

100 MB is a couple of hours VoIP use, by some people's reckoning

Or have you compressed it by using a GSM codec, and does this work?

measuring voipcheap with netlimiter i got 0.2kb/sec

umm, that's a lot less than GSM

bits/Bytes? decimal point? 0.2Mb/s? (which is ~ 70 MB/hr)

kb = kilobytes. actually it's upto 4kb /sec - it rises after a bit

If voipcheap is transfering 70MB/hr then for me it has been 7 GB for 100 hours as my computer is running for the whole week with voipcheap, SJphone, voipstunt,skype along with yahoo msn and outlook. I think 0.2kb/second is fair enough. 200 bytes per second means 2 kb in 10 seconds. 12 KB in 1 minute and 120 KB in 10 minutes. This will end up to 720 kilo bytes per hour. So voipcheap is less than a MB per hour at least. I think this is a fair measure.

Nomee, I think you need to re-read the reply. I didn't say voipcheap used 70 MB an hour, but I have seen the figure elsewhere including my ISP - maybe wrong, or using higher quality codecs

GSM is 9600 bits a second, so it's impossible that any channel can carry intelligible speech at 200.

Hi,
Sorry I was not saying the usage of voip while its carrying speech. i was talking about all the time its ready to recieve call. And about the calculatiosn i was just conforming the that said "i got 0.2kb/s"
Cheers

All, I am no GPRS or WAP expert, but like the ideas in this thread.

Has anyone got voip working via GSM WAP, what about quality?, whats the cheapest way to do it. I have a pocket ppc running wm2005.

WAP is for `webpages`:

WAP works over GPRS and GPRS is too latent - there's a 2-3 second delay when you speak

I don't know what I'm talking about, but this thread seems to be searching for something similar to this.
