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:

// 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.
