If you want to be billed by the second and have the choice of 100% call quality, the professional betamax clones (you can use them in the same way as the others, also with MobileVOIP):

• have 1 sec. billing
• support an unlimited number of simultaneous call channels
• have 3 quality route rates (grey - standard - premium), grey being the cheapest with lowest call quality or connection success rates, standard is usually always good, premium is comparable to the top telecoms.

Example:

VoiceTrading. Wholesale VoIP solutions

A-Z Voip telecom Termination worldwide


edit: this also answers the comment of one of the above posters who didn't want to sometimes risk some little degraded call quality (doesn't happen often, mostly sometimes when calling some "exotic" countries); (use the standard or premium routes for this).

Except callcentric which other voip providers with did numbers support sip uri forwarding?

Voip.ms supports SIP URI forwarding.

If talking about the better ones:

• Anveo (limits on free accounts)
• Voip.ms (also free inum) (needs to load some credit to waive all limits, the credit doesn't have to be used afterward).
• sonetel (also free inum + local access numbers in some countries not found elsewhere, i.ex: Thailand. I also use it to complement the Sipbroker and Inum local access numbers.)
• ...

And several providers who don't support external sip uri, forward to inum for free (so you can get the same result). I.ex:

• localphone.com , forward to your callcentric inum and from there you do whatever pleases you.

For the others with no sip uri or inum calling, no problem either. You can bind them together with a cloud PBX to manage and link all your SIP accounts and devices together in one place. I.ex:

• pbxes.com (also offers free accounts)
• sipsorcery.com

very cheap DID local numbers with sip uri forwarding: https://didlogic.com/purchases/new

Thank you MKB.

I'm really considering switching my GV number to Anveo for 24 dollars per year including free number porting.

This way I can transfer incoming calls to both US numbers of XXsim for free and forward incoming sms via the HTTP pro option for 4 cents per execution and 5 cents per message.

And when this robust setup is working condider the cheaper alternative: transfer via cheapers VOIPs and cheaper SMS http send providers.

Thank for this info and your advice!

localphone.com does. Though they require an actual IP address as opposed to a DNS name. So you can use foo@127.0.0.1 but not foo@example.com

so what is the IP address of hotvoip?


For a provider that does not support iNum, but will forward to a SIP URI, you can send the call to 88351000xxxxxxx@sip.inum.net . A minor disadvantage of the URI method is that the caller will occasionally hear a message "Please wait while we attempt to connect your call."

For use (free) with Rebtel or Localphone numbers that are not yours:

If you have a contact for whom one of these numbers is a local call »www.rebtel.com/en/Get-Help/Access-Numbers/ , add them as a Contact in your Rebtel account. Add (and verify) your iNum (with any provider) to your Rebtel Phones list. Set that number as Preferred.

On the main My Rebtel page. showing your Contacts, click the new entry, as if you were going to edit it. On the screen that appears, you'll see "xxxxx can call you back - Find out how". Click that link and a screen will appear that shows a number local to your Contact. When they call that number (from the number in your Contact list), your iNum will ring. The call is free for you and you don't even need to ever fund the Rebtel account, if you don't use it for any real calls.

On Localphone, it's a little tougher -- you have to use it "backwards", setting up your contact's number as 'yours' and your iNum as the Contact. Set your Location to the contact's city and you'll see the number s/he should call in your Local Numbers. This backwards mode creates a possible security issue, if you don't completely trust the contacts. You can prevent them from making arbitrary calls, by setting a PIN that they don't know, but they could still call your other Contacts. For example, if both your brother and sister were on your account as both Phones and Contacts, they could call each other on your nickel! Also, although calls forwarded to iNum are free, Localphone won't allow them without a positive balance. So, you'll need to pay at least $5, even if you don't use Localphone for any paid calls. Balances do not expire.

You can find that out on Windows from the command prompt with 'nslookup'


On Linux systems you can use 'nslookup', 'dig' or 'host' to find it.

Here is an example on Linux:
$ nslookup hotvoip.com

That is one of many IP adresses. All the betamax/finera clones use the same server park and have multiple IP adresses that are routed by load using the DNS names.
e.g. right now it returns 77.72.169.131 and not 77.72.174.52

Many worldsims seem to be made for voice. Data is mostly a bit expensive.

The only sim width cheap data I've found so far is Piranha sim.

Are there more good sims for data (EU + rest of Europe)?
