407 Proxy Authentication Required

[wjgilmore]

Hi,

I'm sorry to bother you but I'm at wits' end attempting to get past this 407 Proxy Authentication Required issue. I'm providing my SIP username and password using setUsername() and setPassword(), respectively. I've confirmed the authentication works by way of making a successful call using Zoiper. Yet no matter what I do with the php-sip package I receive the 407 Proxy Authentication response.

--> INVITE sip:6149998888@gw1.sip.us SIP/2.0 <-- SIP/2.0 100 Trying

<-- SIP/2.0 407 Proxy Authentication Required

--> ACK sip:6149998888@gw1.sip.us SIP/2.0 --> INVITE sip:6148675309@gw1.sip.us SIP/2.0

<-- SIP/2.0 100 Trying New dialog: 92381.2484f1a5f06b7307c34ab1dd8d74150a.33cc.29daf5ef3b7663e00f2db8077dee2963@173.236.165.43

<-- SIP/2.0 407 Proxy Authentication Required --> ACK sip:6149998888@gw1.sip.us SIP/2.0

Any ideas? My code is effectively identical to that used in the README (SIP numbers/passwords etc removed):

<?php

require_once('PhpSIP.class.php');

    try {

      // if you get "Failed to obtain IP address to bind. Please set bind address manualy."
      // error, use the line below instead
      $api = new PhpSIP();

      $api->setDebug(true);

      $api->setUsername('123456789');
      $api->setPassword('password');

      $api->addHeader('Subject: click2call');
      $api->setMethod('INVITE');
      $api->setFrom('sip:123456789@gw1.sip.us');
      $api->setUri('sip:6149998888@gw1.sip.us');

      $res = $api->send();

      if ($res == 200) {

        $api->setMethod('REFER');
        $api->addHeader('Refer-to: sip:6149998888@gw1.sip.us');
        $api->addHeader('Referred-By: sip:123456789@gw1.sip.us');
        $api->send();

        $api->setMethod('BYE');
        $api->send();

        $api->listen('NOTIFY');
        $api->reply(481,'Call Leg/Transaction Does Not Exist');
      }

      if ($res == 'No final response in 5 seconds.') {
        $api->setMethod('CANCEL');
        $res = $api->send();
      }

      echo "RESULT: " . $res;

    } catch (Exception $e) {

      echo "Oops... Caught exception:";

      echo $e;
    }

How did you resolve this?

Hi @gaethofs I have no idea why I closed the issue without any followup response, and apologize. I spent days working on this before finally giving in and calling SIP providers until I could get an expert on the phone. IIRC he told me what I was trying to do wouldn't work, at which point I called it quits. This was a side project, and never went anywhere.

Fixed the send() function in this commit: #13
I also added a helpful function getCode(), so the call progress can be tracked.

I updated the code to suit my needs (I want to check if a call can be established), but you can get the idea:

$api = new PhpSIP();

$api->setDebug(true);

$api->setUsername('admin');
$api->setPassword('password');

$api->addHeader('Subject: call');
$api->setMethod('INVITE');

// username + server hostname
$api->setFrom('sip:admin@myhost.com');

// who we are calling
$api->setUri('sip:12223334455@myhost.com');

/*
1. this sends the initial INVITE
2. then handles the response of 100 Trying
3. then waits for the 401 Unauthorized
4. and then reissues the INVITE.
5. returns 100 Trying
*/
$res = $api->send(); 

if ($res == 100) {
	// received "SIP/2.0 100 Trying". We should already be authorized at this point.

	$res = $api->getCode();
	if ($res == 180) {
		// received "SIP/2.0 180 Ringing"

		// $api->setMethod('BYE'); // can hangup here, not wait for session progress
		// $res = $api->send();


		$res = $api->getCode();
		if ($res == 183) {
			// received "SIP/2.0 183 Session Progress"

			$api->setMethod('BYE'); // hang up immediately
			$res = $api->send();

		}
	}
}

if ($res == 'No final response in 5 seconds.') {
	$api->setMethod('CANCEL');
	$res = $api->send();
}
