Build an integrated platform for VoIP to make work easier (1)

With the rapid development of information technology in the world, especially the popularization and application of Internet technology, coupled with the loss of a globalized economy, the enterprise market is getting wider and wider, and the regional restrictions are getting smaller and smaller, it is not uncommon for international giants to set up factories and offices around the world. However, the disadvantages brought about by globalization are also obvious, that is, due to regional reasons, the enterprise internal communication has higher and higher requirements on network security and the quality of voice services.

I. status quo and problems in establishing VoIP

Although the traditional PSTN Telephone Network is easy to set up, for multinational enterprises and large enterprises, the monthly international and domestic long-distance calls must be a huge expense, the security of the Internet does not reassure enterprises with the network. However, with the rapid development of VoIP technology, people gradually get a taste of the sweetness, coupled with the effective combination of VPN technology, through VPN to carry IP voice data, not only can provide high-quality VoIP applications, it can also ensure the security of voice data.

According to the traditional network architecture method, the first thing is to implement network communication and ensure communication security through routers, switches, firewalls (software or hardware, the VPN gateway, voice gateway, and switch device are then configured. If the entire enterprise is highly dependent on network services and has high security requirements, it may even deploy intrusion detection/defense systems. However, network products on the market are of different quality and different brands. Different devices need to be connected through physical and logical links to build a redundant and complex network. In this way, the one-time investment is not considered, but the maintenance cost is also a huge expense in the future, and the technical requirements for maintenance personnel are also high; the management is also more complex, with many fault points, once a problem occurs, troubleshooting is troublesome.

If you can integrate routing, switching, VPN, firewall, IDS/IPS, VoIP, and other required functions into a single device, you can combine them in a modular manner, this not only greatly simplifies the traditional complex network architecture, but also facilitates later management and maintenance, and saves a lot of manpower and material resources, it can be said that it is a comprehensive network solution that is the most complete, flexible, simple, cost-effective, and convenient.
