VoIP calls that sound better than landline

Huge savings and no roaming charges

Make SIP calls from anywhere in the world and save. Stop paying the ridiculous $3 per minute roaming rate by making calls from your SIP-enabled device instead, or use our Webcall feature to instantly conference in any two phone numbers.

Unbeatable low rates

Rates start from just $0.002/minute. There are many destinations that cost less than 1 US cent per minute to dial:

  • USA $0.006/min
  • Denmark $0.008/min

Skype will charge you $0.30 per minute, one averaged-out rate for all UK mobiles – we charge $0.02 to French mobiles and $0.03 per minute to UK Vodafone, O2 and Orange. There is no VAT, and no other taxes of any kind. Same transparent and logical pricing applies to all other mobile networks in the world.

Call quality that is second to none

Most "cheap VoIP providers" have hidden technology in place to economize on bandwidth and send your calls to the cheapest reseller available. They use many elaborate routing schemes that ultimately result in poor voice quality and dropped calls. DID Logic does not use any least cost routing mechanisms, or so-called "grey routes", or compressed voice codecs. We encourage you to use G711 or G722 HD voice with your device. Use as much of our bandwidth as possible – our goal is to provide ideal, absolutely perfect voice quality. We do not economize on bandwidth or network resources to squeeze margins. Your calls are sent directly to the international carriers responsible for call termination in the region your dialing - with the exception of extremely isolated territories, such as remote islands in the Atlantic or Antarctic, where traffic is sent via the so called "partner direct" route. You get the best TDM quality possible in the industry. This is truly the highest quality international call service available.

Your unique Caller ID is sent with the call
