A PBX (Private Branch Exchange) is a private telephone network used within a company or organization. Traditional PBX systems are landline-based and require physical connections and infrastructure. However, PBX systems have evolved with the advancement of technology.

Now, we have the 4GPBX system which is wireless and uses cellular networks for connectivity. There are many advantages of having a 4G/5G-based PBX:

1. **Mobility**: Access the system from anywhere with a 4G/5G signal, perfect for remote work.
2. **Scalability**: Easily add or remove users without physical installations.
3. **Cost-Efficiency**: Lower setup and maintenance costs, and potentially cheaper call rates.
4. **Advanced Features**: Enjoy sophisticated features like voicemail to email, call forwarding, conferencing and more.
5. **Business Continuity**: Less vulnerability to local infrastructure disruptions.
6. **High-Speed Connectivity**: 5G provides clear, lag-free communication.
7. **Integration**: Connect with other business systems like CRM and collaboration tools for improved productivity.
