Hi guys, just moved to NZ, never used VOIP before. I hope this question isn't stupid, but since most broadband packages here have a download limit, how much does VOIP use? Enough to push you further to the limit?
Cheers

sbiddle: What sort of VoIP are you talking about? Skype, SIP? If it's a SIP provider what codec do you plan to use?
And more importantly how often do you plan to talk for? If you're talking for an hour a month you'll be looking at somewhere in the vicinity of 25MB - 60MB in total. Talk for 20 hours per month and that'll be somewhere in the 500MB - 1.2GB range.
If you are with ISP's who offer a VoIP service such as Xnet then VoIP traffic to their own VoIP service does not use any data.

Hi. I'd heard 2Talk is good. Didn't know about codecs for SIP. Is there a sticky here about CODECs? I reckon about 5 hours a month SKype and the same by SIP. Do your figures apply to both skype and SIP? If they give me a good ballpark figure, thanks thats v useful.
kiwiscoota: Codecs are used for all internet voice and or video transmission to compress the data.
There's a calculator available at http://www.asteriskguru.com/tools/bandwidth_calculator.php
Using that calculator, you need to select
(1) Regular Audio Codecs then the Codec you wish to use, I use G711.
(2) You can ignore the Speex Audio Codec line
(3) Select SIP
Note that the data usage is quoted per second,
eg G711 : Total bandwidth (incoming and outgoing): 159.26 Kbps
I would expect Skype to use similar bandwidth.
sbiddle:
Skype uses a lot less (assuming it's an audio only call). G711 is an uncompressed PCM codec so uses a lot of bandwidth. All new codecs offer some form of compression.
Skype usage is typically around 30kbps - 50kbps for an audio call, depending on the codec. Video will of course up that.
