Implement a Voice over Internet Protocol network solution in Cisco packet tracer

Description:

Introduction
You are part of a telecommunication company that provides network and security solutions. A client has called you to plan and design the network system and the company's needed security controls. The idea of this project is to create a full connectivity network infrastructure across multiple locations. Your job is to propose and design an integrated solution based on the following requirements.
The Network Requirements
The client is a UAE based company that has different and remote locations. During the network design, the team should take into consideration the following networking techniques that may be used all or be used partially according to the company size and requirements:
• At least 3 different sites (in other cities or countries). You can propose more locations. However, you must be sure that all of them are connected to one network.
• Frame Relay networking between sites. • PPP Networking between sites.
On the other side, and regardless of the company size, all companies require a high-security level to be achieved. Here are the set of security techniques that you must use in the design and implementation of the company network:
• PPP with Authentication between any two sites.
• Firewall Server.
• Syslog and NTP.
• VPN technology (Site-to-Site VNP).
The techniques mentioned above are mandatory to be used in the design and implementation of network security as part of the project. Moreover, the students may use more security techniques, such as implementing the AAA server or deploying an Intrusion Detection System (IDS) for securing the company network. This will be considered a bonus, and the students will have additional marks during Grading
