I have read the previous comments on this and as I was in the process of purchasing a Jas Jar with the view to using VOIP I wanted to get to the bottom of it.
After a number of discussions with various Vodafone staff I can report the following.
They say that they simply dont support VOIP on their 3G data network.They are not blocking it...they say they simply dont support it because of "latency" problems with it and that when they roll out faster systems that this will hopefully disappear.
I suggest that their wording is rather sloppy and has giving room for many interpretations some of them quite wrong.

So there is no breach of contract situation or risk of unseen billing as some may have suggested.

I guess in the long run it pays to get it from the horses mouth.
Cheers

Thanks for that.
In real life situation I have found Skype run over wifi or 3g has been fine and not an issue in any case.
I thought it would be off that they "could dictate what you did with your data"
So it was more they did not "support" being the keyword here

Is this word from a Vodafone Store, or from Vodafone New Zealand? Vodafone Stores do not represent Vodafone, since they are independent dealers.

Though you can run a VoIP client on your Windows Mobile device or laptop with a MCC, I wouldn't do it. They are clear on the website (here and here) about VoIP being excluded from the services.

They can't (easily) interrupt Skype traffic for example, but SIP servers are easy to block because most use specific ports.

Hi,
No I definately talked at length to Vodafone themselves..not a store..and I kept going till I got to the bottom of it. !!
And they stated that they simply did not "support" it , were not blocking it, and even suggested that I email them in regard to my suggestion that they changed their wording so that there was NO CONFUSION over the subject.
I have done so and been told that my enquiry had been taken seriously.

Cheers

The policy is not NZ specific, it's a Vodafone Group thing. Vodafone networks in other countries (Germany for example) have gone to great lengths to physically block VoIP applications from being used.

Vodafone NZ may have told you one thing but the simple fact is it's not a decision being made by them.

This brings up the obvious question as to why they would do this??

Hmmm. I have to stand correct here. I had lunch today with VFNZ and asked about this. Their version is "we don't block and don't say you can't use. Just don't ask us if it doesn't work". Or something along these lines...

I guess with HSDPA and lower latency this could work ok on WCDMA. Currently I tested in both WCDMA and CDMA EVDO, and the latest is of course better in terms of quality.

VoIP works quite well using a Vodafone 3G connection and G.729 codec. With the increase in upstream speeds to 128kbps I'll have to test u.law/a.law and see how well it works.

I was directed to this thread by someone I was talking with earlier regarding this situation.

What gunfighterkid has heard from Vodafone is correct, it is not a supported service - which means dont call us if it doesnt work. It is not actively blocked, but Vodafone doesn't guarantee it will work either (due to some latency issues experienced on 3G). With the next data network upgrade "coming soon" this will reduce problems some people might experience using skype over the current data network. I know people around me that are currently using Jas Jar's with skype software on them.

Jon.

Well I guess that just about closes this topic off , now that you have all had it from the horses mouth ( so to speak)
So we are all one step closer to giving up the old copper lines !!

Thanks Jon for clearing this up

The only issue with using VoIP over a current mobile connection (whether it be Vodafone or Telecom) is that the technologies are not permanent 24/7 internet connections and your phone still has to initiate a data connection. For outgoing calls this would not be an issue but for incoming it could be.

Theoretically you could get around 1800 minutes of voice calls using g.729 for 1GB @ $49.

I have used voip over vodafone recently and have to admit, i was quite surprised by how well it worked. My telecom evdo connection worked flawlessly though of recent, i have been having problems with it dropping back to 1x for no apparent reason, congestion?. early tests on datacard huawei and pc over umts seem to be flawless. hmm, if only for a umts or evdo smartphone!
