Callwithus VoIP Service

Callwithus is a company that offers broadband telephone service using VoIP (Voice over IP) technology. Whether from a phone adapter or ATA (Analog Telephone Adapter) making or from a personal computer, making phone calls to any country is possible.  You can use any SIP (Session Initiation Protocol) well-suited phone adapter or a “softphone” – that is a program which turns your personal computer into a powerful VoIP client using software

The good thing about Callwithus is the service is all free. You only pay for the calls you made. There are no hidden charges or recurring fees unless you order additional service from Callwithus like actual phone number (that would be DID – Direct Inward Dialing) to receive calls from a public telephone network or VoiceMail service.  Regardless of where you are and what time it is, all calls between Callwithus own subscribers are free. Payments are thru Paypal, credit card or Bitcoin. You can even dial their echo test 3246 to check your VoIP configuration before making a payment.  You can buy credits for as low as $5 to your account.  However being inactive with no PSTN activities will have your account deactivated.

Callwithus offers wholesale A-Z termination rates to VoIP service providers. Wholesale rates are billed 6/6 USA and Canada, 60/60 Mexico and 1/1 to most of other destinations.

Moreover Callwithus do not offer service plans that are unlimited calls with having to pay monthly service fee like most common providers these days have.  It is simple, you build your own plan, include only the feature you need most.  The calling rates do not depend on your location. All you need to use their service is a broadband connection to the Internet. However, it requires that you have at least 128Kb upstream and downstream speed.

Also, you may choose your own phone number. There are many countries and areas to select from and you may select a number from any of these countries, regardless of your location. The calls to your DID number will be redirected to your SIP phone, regular PSTN or cellular phone. Good thing you don’t need a VoIP client to have calls to your DID redirected to your PSTN or mobile phone number.

Voicent on the other hand offers software that would help you or say your business to your profitable years and enable more efficient call and voice communication.  Voicent can be integrated to use Callwithus as VoIP service provider.
