To begin, you'll need to set up a server for sending out capability
tokens. We've included a PHP sample file called auth.php that's in
the server/ folder next to the Eclipse project that can create tokens.
Note that this also makes use of Capability.php from the
Twilio PHP helper library.
<?php include "Services/Twilio/Capability.php"; // AccountSid and AuthToken can be found in your account dashboard $accountSid = "ACXXXXXXXXXXXXXXXX"; $authToken = "your_auth_token_here"; // The app outgoing connections will use: $appSid = "APabe7650f654fc34655fc81ae71caa3ff"; // The client name for incoming connections: $clientName = "monkey"; $capability = new Services_Twilio_Capability($accountSid, $authToken); // This allows incoming connections as $clientName: $capability->allowClientIncoming($clientName); // This allows outgoing connections to $appSid with the "From" // parameter being the value of $clientName $capability->allowClientOutgoing($appSid, array(), $clientName); // This returns a token to use with Twilio based on // the account and capabilities defined above $token = $capability->generateToken(); echo $token; ?>
Making a request to this file on a PHP server will output a string that,
when given to a Device, grants it capabilities such as making outgoing
calls or allowing incoming calls.
Note that the token generated is valid for 1 hour unless otherwise
specified. To specify a different period of time, pass in the number
of seconds as an integer parameter to generateToken() -- for example,
for a token that expires after 5 minutes, call generateToken(300).
The maximum allowed lifetime for a token is 24 hours.
To fetch the token, put the auth.php file and Twilio Helper Library
PHP files on your server, and then modify the $accountSid and
$authToken to be values from your Twilio account. To make sure it
works, open a web browser and hit the URL (e.g.
http://companyfoo.com/auth.php). Assuming there aren't any issues,
you should see a long string of text -- this is a capability token for
the user named "monkey" to receive incoming and make outgoing calls.
Now let's walk through making an outgoing call to a phone number. This code can be run either in the Android Emulator or on your device.
