Possibly voipcheap.com, see the Betamax comparison chart here:-

dialnow.com is cheaper, but it's not SIP.

thanks medwayman, I'm currently using voipcheap.co.uk

that betamax chart is not up to date ... it's hard to keep up with betamax providers because they seem to change their rates on a regular basis.

If you don't mind losing sip calls, justvoip are pretty much the cheapest for everything (6.5 eurocents/min to uk mobiles), and they do 120 days free calls where some of the others are only 90. Dialnow are 6 cents/min, but they don't do free calls to landlines.

Justvoip also have the nice little addition of free sms to UK mobiles - this is quite useful if you use the app to verify your mobile, then it presents that number as the source of the SMS.

If you want to use SIP, I think voipcheap.com are the best of the bunch. Only 90 days of course, but you can surely use the 10 euros on calls to mobiles by that time, and 8 eurocents/min to UK mobiles.

Voipcheap.co.uk are a lot more expensive than .com btw, on pretty much every destination - they're twice the price to mobiles for example, and don't do free calls to landlines either.

The chart looks up to date to me btw.


Edit: forget to add I used all pre-vat prices. You essentially need to add 25% to anything above, since to pay 10 euros you actually get charged 12.5.

You might well find that you can use SIP with justvoip.com. Certainly sip.justvoip.com is pingable, and that, combined with "linux and Mac users click here" on the website is usually the clue with Betamax. Don't have time to test right now, but I will as I call mobiles a lot!

Far as I know, the backsla.sh page is updated daily by a script. Never had bum info from it, but never extensively checked either.

Hi, try these guys - www.asergis.com
when you call a mobile it displays your number so people know who is calling.

The rates are on there site.
