DTMF

Audio works again on Chrome

Wednesday, 16 August 2017

We had been receiving reports from some Chrome users that in-browser audio for making and receiving calls was not working. After some investigation we traced it to a bug in how Chrome handles the Content-Security-Policy header, which we use to prevent loading any content from untrusted locations. We have implemented a workaround, and audio should work in Chrome again.

New number types, and removal of premium-rate numbers

Thursday, 3 August 2017

We've added numbers from Korea, Malaysia and Taiwan, and have unfortunately had to remove premium-rate number support due to a regulatory change. Affected customers have been contacted.

Another price drop

Tuesday, 6 June 2017

We've linked up with another provider allowing us to drop the prices significantly. Enjoy!

Premium-rate numbers, local numbers & voice improvements

Monday, 5 June 2017

You can now make money using DTMF – we now offer premium-rate numbers where we pay you for every inbound call minute your number receives.

We've also launched a range of local numbers, and improved our voice implementation to work on a wider range of browsers.

API & Latvia numbers

We've just launched our API with support for all functionality except voice. We also added support for Latvia mobile numbers (SMS only).

Price reduction for new number rentals & Portugal numbers

Tuesday, 9 May 2017

We have dropped the prices for all new number rentals, thanks to the high USD value of Bitcoin at present. We've also launched Portugal mobile numbers (SMS only).

Pristine number rentals available

Wednesday, 26 April 2017

We now offer rentals of "pristine" (previously unused) numbers, for an additional cost. Choose "rent a new number" on your "numbers" page to see the pricing.

Increased capacity

Monday, 24 April 2017

We have had some periods recently where users were unable to get certain types of numbers due to all numbers in that pool being in use. Today we've increased the capacity of all number pools to cope with increased demand.

ShapeShift integration

Sunday, 26 March 2017

We now integrate with ShapeShift to allow you to fund your DTMF account with any altcoin they support, including Monero, Zcash, Dash, Ether, Litecoin and many more.

Voice support

Friday, 10 March 2017

We now support voice as well as SMS. For numbers with voice support (currently France and Germany only), you can make and receive calls from within your browser. This feature requires a modern browser (a recent version of Chrome/Chromium, Firefox or Edge). If you are using an unsupported browser the controls to make and receive calls within the browser will not appear. As before, numbers with voice support also support forwarding incoming calls to any number.

Webhooks

Thursday, 2 March 2017

You can now handle SMS messages sent to your numbers using your own code. Just set the number up to handle incoming messages using a webhook, and we will do an HTTPS POST to the URL you supply. The body of the POST request will be a JSON document with two keys: sender and body. If you return 200 OK with non-empty plain text content, this content will be sent back to the sender of the message as a reply. At present, replies longer than 160 characters will be truncated. A non-200 HTTP status code or an empty response body will result in no reply being sent. Note that your webhook handler must be served over HTTPS. Non-HTTPS URLs will be rejected.

Spanish mobile numbers

Thursday, 2 March 2017

We just launched Spanish mobile numbers with support for SMS only. Enjoy!

Features currently in development:

  • Dial-in numbers allowing you to make long-distance calls via DTMF (and optionally use the caller ID of any of your numbers)
  • Voicemail support for numbers that support voice
