VoIP Protocols and Types of Architecture
Voice-over Internet Protocol, also known as VoIP, has been creating a buzz for more than five years now. Before, we communicate with distant people using telephone, our primary mode of communication. VoIP has taken over this basic means of communication, we now converse through the use of computers.
Computers initially aimed for just speedier calculations, its main purpose was to make life easier at work and at home. It never struck people as a communication tool up until recently. Internet turned the leaf of communication, one of its primary uses now is communication and data sharing.
There are four different tools for voice transfer, namely IP Phone, IP Converter, Line gateway and fully IP enabled PBX system. Conventional voice carrying system used to convey analog signals, IP enabled VOIP system now transfers digital signals. That is the main difference between the two.
The main protocols used in VOIP are SIP, H.323, MGCP, and H.248/Megaco. Basically, there are two types of architectures in VoIP: centralized and distributed. The said protocols and their used depend on the architecture used for VOIP system in the organization. Say, MGCP and H.248 protocols are used in centralized type of architecture while SIP and H.323 for distributed type of architecture.
These terms may sound very technical but it doesn’t change the fact that VoIP is the future of communication. VoIP offers an array of advantages. To name a few, the cost, data & voice integrated systems and open standards. No additional costs for any calls, unlike the conventional switch network. Additionally, it offers the convenience of your computer being single terminal for all your communication and data sharing needs.
