Mobile VOIP Access (With PDA?)

Ivor Please Ignore - I am not advertising TMobile.

I am interested in VOIP over mobile networks. Previously i didn't
consider GPRS to be fast enough for voip access.

3g seemed too expensive and unworthwhile. However Tmobile have released
a new product. 10GB cap £22.50 p/m
http://www.theregister.co.uk/2006/09...e_voip_tariff/

This, in my opinion has made VOIP over mobile viable. Has anybody else
looked into this? I reckon conventional mobiles wouldn't really support
it, but PDA's might - with the right software.

Has anybody any experience with PDA's, VOIP and 3G?

The 3g connection would have to be constant to accept incoming calls, is
this possible with PDA's? Can you easily VPN into a VOIP PBX?

Why bother Ivor don't own this group although he thinks he does
you only need to just whisper the name of a company and he will accuse
you of being a spammer.

Your out of luck.

I think you will find that T mobile have placed a ban on all VoIP
activited accross their network

Ivor will not bite. He is above that. He is finding inner peace.

Now then, may I help you with anything?

I have been watching that closely but the link in my original posting
says that they have dropped it.

But to be honest, if you could route it through a VPN then they could
not stop you using VOIP as they would have no way of knowing.

If you want to make *lots* of VoIP calls it could be worth your while.
Bear in mind that this is on top of your monthly rental so for less
total money you could have 900 inclusive minutes on flext price plan
anyway.

Exactly how many minutes you would get in 10GB would vary according to
protocol and compression used but I think you would need the phone
pretty much stuck to your ear to see any real cost benefit. Which is
presumably what T-Mobile are banking on - the mobile operators are
generally about as keen on replacing voice calls with VoIP as turkeys
are on Xmas.

I suggest that tunneling any VoIP protocol is not for the
faint-hearted, the simpler tunneling techniques do not work with UDP.
Setting up VPN from a PDA to a server is going to depend on your PDA,
your server and very probably what switches/routers you have between
them.

Dex, comments like that really don't help you! Personally i use
Sipgate, but disagree with Ivor's unrelenting 'selling' of it.
Especially if somebody else mentions a company he flames them as
spamming.

However, you really shouldn't make digs you above, as it adds substance
to his argument.

Nic, thank you for taking the time to post your comments. However, the
real attraction to this new service is that it appears to be purely a
data bundle as it mentions on the link i originally posted: "It'll cost
consumer punters £22.50 as a standalone product and £44 for suits, who
get voice bundled in."

The real benefit of this service is not saving money in calls, as i'm
not a huge user - it's the added benefit of having a fast Internet
connection for other Internet purposes for a few extra pounds a month.
Also my mobile number can be a standard area-code / or an extension on
my current PBX. And the other benefit is the most important - novelty!

I'm not at all concerned with the server side of VPN as i currently have
a functional OpenVPN configuration that works with my current asterisk
setup. The real concern is how well PDA's work with it - as i'm
currently looking to purchase one.

Thanks again for your feedback Nic.

Web'n'walk currently works as a standalone for laptops (with a
datacard) or a free-standing addon to their monthly tariffs for
mobiles. I'd wait to see the actual product announcement before
assuming that this is approach is being thrown away by T-Mobile. If all
you want do do is put a data-only (i.e. no phone calls at all) SIM into
a PDA you can already do that by taking the SIM out of a datacard -
although I would agree that the new T-Mobile deal will be a good bundle
for heavy data users (and way cheaper than the Vodafone equivalent, for
example).

Bear in mind that on a data-only tariff it will not functionally be a
phone - its a super-portable computer with a better form factor for
VoIP than your average hardware. If you do go for it let us know how
you get on, I'm sure there will be interesting challenges along the
way.
