said by Morac:An uncompressed voice stream on the PSTN is 64kbit/s. Every VoIP implementation that I've seen uses compression/codecs to reduce this, sometimes to <20kbit/s. At 64kbit/s you could talk for eight hours a day and come out with a monthly total of 6.7GB. The actual usage would be substantially less than that.
Or did you think that VoIP somehow magically works without sending or receiving data?
Caps are meaningless in the context of VoIP.
