How can I get in contact with a developer?

To speak directly with one of our developers, please include this request in your message when you contact support.

Where can I read about what’s changed on the platform or see release notes?

All FreeClimb release notes and other important API information can be found in the changelog.

What’s the difference between the REST API and Performance Command Language (PerCL)?

The REST API handles application-initiated actions and making requests to your application while PerCL is a command language, which you can use to direct the API. For example, if a call comes onto the platform for a number you’ve purchased and assigned to an application, the REST API will make a request to that application at the endpoint you’ve specified. In your application’s response to the request, you can return PerCL that instructs the API what to do with the call. For more information, please reference our PerCL and API documentation.

Does FreeClimb have built-in grammars for voice recognition?

While FreeClimb does not currently provide built-in grammars for voice, we offer a guide on How to Write Grammars. You can also use third-party speech recognition tools, such as Google Cloud’s Speech-to-Text.

Why do I need to verify outbound numbers with my trial account?

To prevent misuse of the platform and keep FreeClimb free of spammers, all trial users are required to verify outbound numbers prior to use. For information on how to verify outbound numbers, please reference Using Your Free Trial Account. NOTE: only US numbers are supported at this time.

Why should I choose a toll-free number vs. a long code number?

Toll-free and long code numbers differ in terms of capability and cost, so they should be selected based on your specific use case. To match your use case with the most appropriate number type, please reference Understanding Number Types.

Does FreeClimb offer short codes?

This feature is not yet available for most users. Contact sales at for more details.

What types of audio files are supported for recording?

FreeClimb supports playback of single-channel, 8 kHz, 8-bit μ-law WAV files. These files must be stored in a location that is available via URL. You can convert files to this format using an audio editor. Audacity is a free, open source option.

  1. Import the source audio.
  2. Adjust the project rate to 8 kHz.
  3. If the source is recorded in more than one channel, convert it to mono.
  4. Export the track, selecting the μ-law encoding.

The FreeClimb support team is available Monday – Friday, 9-5pm CST to answer any and all inquiries.
