VoIP System Development Using free Core Frameworks
Budget: ₹14,000 – ₹18,000 INR
Development- Free IP Calling app to mobile and phone with custom ID feature (iOS & Android with admin portal)
Basic Development Rules
1- Voip app require for caller only
2- Not required any app to receiver
3-Only active user can be use this service
4- Smoothly call to receiver's mobile or landline as normal
5- No paid API uses,
6- All technology to be uses free only
Core Frameworks and Servers
These platforms form the backbone of a VoIP system, handling signaling and media traffic:
Asterisk: An open-source framework for building communications applications, often used to create a custom VoIP phone system (PBX). It has a large developer community and supports various protocols.
FreeSWITCH: A free and open-source telephony platform for creating voice and messaging applications, known for its modular design and high voice clarity.
Kamailio: A high-performance, open-source SIP server that can handle thousands of calls per second, primarily used for building scalable real-time communication applications.
WebRTC (Web Real-Time Communications): An open-source technology developed by Google that enables browser-based voice and video calls without needing extra plugins. This is ideal for web-based applications.

Development Tools and Libraries
For client-side app development, you can leverage specific SDKs and libraries:
Liblinphone: A VoIP SDK (Software Development Kit) provided by the Linphone project for building mobile and desktop apps.
PJSIP: A small-footprint, high-performance, and portable SIP stack written in C, with language bindings for Python, suitable for developing custom softphones.
SIP.js: A JavaScript library for SIP signaling, specifically designed for WebRTC developers.

Open Source Softphones (Clients)
If your goal is to use an existing, white-labeled, or customizable app rather than building from scratch, these options are available:
Linphone: A free, open-source softphone client for multiple platforms (iOS, Android, Windows, macOS, Linux) that supports HD audio/video and messaging. Developers can modify and rebrand it.
Jitsi: An open-source platform that offers secure video conferencing and VoIP services. It provides both a hosted service (meet.jit.si) and self-hosted options.
MicroSIP: A lightweight, portable, and open-source SIP softphone for Windows, based on the PJSIP stack.

Development Approach
To develop a free VoIP app using open-source resources, the general approach involves:
Set up a backend server: Install and configure an open-source PBX or server like Asterisk or FreeSWITCH on your own server hardware.
Select a client-side strategy:
Customize an existing softphone: Fork an existing open-source client like Linphone or Jitsi and modify its source code to suit your needs.
Build from scratch using an SDK: Utilize an SDK like Liblinphone or PJSIP to build a unique app, offering maximum customization.
Web-based application: Use WebRTC and a JavaScript library to enable communication directly in a web browser.
