Sipit

A SIP library to send OPTION pings to publicly open SIP devices out in the wild. SIP (Session Initiation Protocol) is a protocol used in VoIP communications allowing users to make voice and video calls.

use Sipit\SipitFactory as Sipit;

$destination_ip = '192.168.1.100';
$destination_port = 5060;

Sipit::ping($destination_ip, $destination_port);

Summary

Sipit is a simple pinging library for SIP devices. When you call the Sipit::ping() method it'll return an array of information including the request and response. It's good for knowing if a SIP server is alive. A good example is if you're displaying the status of a SIP server, you can use this one method to check that. If an endpoint doesn't respond, it'll return an empty array for the response section.

Installation

The best way to install this library is with Composer.

composer require odannyc/sipit

Or

{
  "require": {
    "odannyc/sipit": "*"
  }
}

Usage

Right now Sipit only has one method, and that is to ping SIP devices, in the future I am planning to add more to it. A simple way to use Sipit is the ping method:

use sipit\SipitFactory as Sipit;

Sipit::ping('192.168.1.10', 5060);

The response will look like this:
