How to make calls and gets events from php or nodejs with TAPI 2.0/2.1 under unix system?

 TAPI (Telephony Application Programming Interface) 2.0/2.1 is a Windows API that provides a standardized interface for communicating with telephony devices. As such, it's not directly compatible with Unix systems. However, there are some third-party libraries and tools that can provide TAPI-like functionality on Unix systems. Here are some general steps for using these tools to make calls and get events from PHP or Node.js:

  1. Install the appropriate library: Depending on your Unix system and programming language, you may need to install a third-party library or tool that provides TAPI-like functionality. For example, the Asterisk PBX system can be used to make and receive calls on Unix systems, and there are PHP and Node.js libraries that can communicate with Asterisk.

  2. Configure your telephony device: Once you have the appropriate library installed, you'll need to configure your telephony device to work with it. This may involve configuring the device driver, setting up a virtual serial port, or other steps depending on your system and device.

  3. Write your code: With the library and device configured, you can now write code to make calls and get events. The exact code will depend on the library you're using and the specific functions you want to perform, but in general you'll need to open a connection to the telephony device, send commands to make calls or get status updates, and handle any events that are returned.

Here's an example using the Asterisk-Java library to make a call from Node.js:

javascript
// Load the Asterisk-Java library
const asterisk = require('asterisk-java');

// Create a new Asterisk-Java client
const client = new asterisk();

// Connect to the Asterisk server
client.connect('localhost', 5038, 'username', 'password', onConnect);

// Callback function for when the client connects
function onConnect() {
  // Make a call to the specified number
  client.action({
    'action': 'Originate',
    'channel': 'SIP/myprovider/1234567890',
    'exten': '1234',
    'context': 'default'
  }, onResult);
}

// Callback function for when the call result is received
function onResult(err, response) {
  if (err) {
    console.error('Error making call:', err);
  } else {
    console.log('Call result:', response);
  }

  // Disconnect from the Asterisk server
  client.disconnect();
}
This code uses the Asterisk-Java library to connect to an Asterisk server running on localhost, and then makes a call to the SIP provider 'myprovider' with the number '1234567890', routing the call to extension '1234' in the 'default' context. The onResult callback function is called when the call result is received, and the client.disconnect() function is used to disconnect from the Asterisk server. Note that this is just a simple example, and the exact code will depend on the specific library and functions you're using. You may also need to handle authentication, error handling, and other factors depending on your setup.

Remove Unicode Zero Width Space PHP

✔ Recommended Answer This: $newBody = str_replace("​", "", $newBody); presumes the text is HTML entity encoded. This: $newBody = str_replace("\xE2\x80\x8C", "", $newBody); should work if the offending characters are not encoded, but matches the wrong character (0xe2808c). To match the same character as #8203; you need 0xe2808b: $newBody = str_replace("\xE2\x80\x8B", "", $newBody); Source: stackoverflow.com Answered By: Jef Method #2 To remove Unicode zero width space (ZWSP) from a string in PHP, you can use the str_replace() function to replace the ZWSP character with an empty string. Here's an example: php $str = "Hello​ World" ; // Contains ZWSP after "Hello" // Replace ZWSP with an empty string $str = str_replace ( "\u{200B}" , "" , $str ); echo $str ; // Outputs "Hello World" without ZWSP In this example, the str_replace() functi

PhpStorm, return value is expected to be 'A', 'object' returned

✔ Recommended Answer Has to be because object can be ANY class instance, even B etc. You can annotate the create() method with generics PHPDoc to tell that the return type will be the same as the input parameter class string. It gives more context info to the IDE. /** * @template T * * @param string $class * @return T */ private function create(string $class) : object { return new $class(); } P.S. Instead of create('B'); better use create(B::class) . This way the IDE can track the usages of that class for refactoring/search purposes etc. Source: stackoverflow.com Answered By: LazyOne Method #2 This error message suggests that your code is expecting a value of type 'A' to be returned, but instead, the code is returning an object. This error can occur in PhpStorm, or any other PHP development environment. To resolve this error, you should check the function or method that is returning the object and ensure that it is returning

Laravel file upload returns forbidden 403, file permission is 700 not 755

✔ Recommended Answer The issue you are facing could be due to incorrect file permissions for the storage folder. Here are some steps to fix the problem: SSH into your cPanel server. Change the permission of the storage folder to 755: chmod -R 755 storage/ This command will change the permission of the storage folder and all its contents to 755, which should give the web server permission to read and write to the folder. Check the ownership of the storage folder. Ensure that the owner of the folder is the same as the user running the web server (typically www-data on Apache): ls -l This command will list the files and folders in the current directory along with their ownership and permission details. Make sure that the owner of the storage folder is the same as the user running the web server. If the ownership is incorrect, you can change it using the following command: chown -R www-data:www-data storage/ This command will change the ownership of the storage folder and all its conten
