Secure way to call Voicent Gateway

when using sample PHP outbound calling app returns that gateway password is wrong, but there is not parameter on example to send the password, when I clear the password on the Gateway works ok. Need more security! what is the correct and secure way to call my gateway?

That is a great question.

Voicent Gateway, when a password is set, will first authenticate a user/request. The authentication method is the Basic challenge-response authentication method used for HTTP. You can find more information about challenge-response authentication method from w3c’s HTTP document.

PHP offers support for the basic authentication (user name and password), so you should be able to use it without too much trouble. For details, please google “HTTP authentication with PHP” or search the official PHP site.
