Frequently Asked Questions
Getting Started
To confirm your Ribbit Developer account is working properly, click here to access our demo test-call panel.

Enter your Developer account information and a username / password that you created to make a phone call. If this test works, the call (or SMS) problem might be within your application. Causes for your failure might be:
- The username you created is not set up for billing. Log into the Developer Center by clicking on the left side that says Users and then clicking "add" in the Billing column that corresponds to the user, or
- Your account has no funds available, or
- The phone numbers are entered in an invalid form.
If your user name and password worked in the past, but, is not allowing you to log in today, please click the "Forgot Password" link at the top of the Developer home page. Then, follow the wizard to change your password and log into your account.

- For
online account access:
- You need to have Flash 9 (or greater).

- Internet Explorer 7 (or greater)
- Safari (version 3 or higher)
- Firefox (version 3 or higher)

- For
Ribbit VoIP phone calls:
- We strongly suggest using a headset with microphone. This will reduce the "echo" you would hear if using PC speaker and external mic.
- You'll also need sufficient bandwidth on your local area network. Minimum bandwidth required for a Ribbit call is 64kb (Flash Nellymoser codec). Click here for steps to test your bandwidth speed.
- Mobile
phones:
- Only mobile phones based in the U.S. or U.K. can be call-forwarded into Ribbit.
- In the U.S. we support AT&T (Cingular), Verizon, Nextel, T-Mobile, and Alltel (Sprint is not supported). All U.K. mobile carriers can be call forwarded into Ribbit.
- No pre-paid phone in the U.K. can be
call forwarded into the Ribbit network. In the U.S., only ATT and Verizon
pre-paid phones can be call forwarded into the Ribbit network. (Click here for details).
Please go to the registration page to sign up for a new Ribbit Developer account.
Registration errors are most likely due to:
1. The verification email landed in you junk/spam folder. Check this folder for an email from developersupport@ribbit.com,
2. The credit card used was invalid, or
3. You are already using the same email address on another Ribbit account. Only one account (whether it's a Mobile, Salesforce, or Developer account) can be associated with an email address. To create a second Ribbit account, you will need to use a different email address. If you wish to delete your original Ribbit account (to free up use of the email address), click here to contact our support team - they will be able to delete your account.

Click the forgot your password? link on the sign in page and you will be asked to enter the email address for the account you wish to be reset. You will then be sent an email with an activation link. You will then be able to reset your password.

Business & Pricing
Finance & Billing
Calls less than one minute are always rounded up to a whole minute. After that, 6 second increments (rounded up) are used. For example:
- 48 second call will be billed as 1 minute
- 82 second call will be billed as 1 minute, 24 seconds
Call charges start when call is answered, not when it starts ringing. Thus, an inbound call which rang for some, but, the caller hung up before being answered (or reaching voicemail) will not be charged.
