Sinch Voice API is a powerful tool designed to facilitate seamless voice communication in applications. It allows developers to integrate voice calling features into their apps, enabling users to make and receive calls globally. The API supports various functionalities, including call control, call recording, and more, making it an essential component for applications requiring voice communication capabilities.
When working with Sinch Voice API, you might encounter an error related to an invalid phone number format. This issue typically manifests as a failure to initiate or complete a call, accompanied by an error message indicating that the phone number format is incorrect.
The error message you might see is: "Invalid Phone Number Format"
. This indicates that the phone number provided does not adhere to the expected format required by the API.
The root cause of this issue is that the phone number provided does not meet the required E.164 format. E.164 is an international standard for phone number formatting, which ensures that numbers are globally recognizable and callable. A typical E.164 formatted number includes the country code, followed by the national number, without any spaces or special characters.
For instance, a US phone number in E.164 format would look like: +14155552671
, where +1
is the country code for the United States.
To resolve this issue, follow these steps to ensure that all phone numbers are correctly formatted before being used in your application:
Ensure that the phone number input in your application is validated to conform to the E.164 format. You can use libraries or regular expressions to enforce this format. For example, in JavaScript, you might use a regex pattern like:
const e164Regex = /^\+?[1-9]\d{1,14}$/;
Use this pattern to check if the phone number matches the expected format.
If you have phone numbers stored in a different format, consider writing a function to convert them to E.164 format. This might involve stripping out non-numeric characters and appending the appropriate country code.
After ensuring the correct format, test your application with the Sinch Voice API to verify that calls are initiated successfully. Refer to the Sinch Voice API documentation for additional guidance on testing and troubleshooting.
