Systems
IP-based telephony systems have emerged as a reliable alternative to traditional communication systems for both business and personal use. These telephony systems can be easily integrated into existing communication platforms since they have well-established standard protocols. IP telephony systems consist of low-cost development tools and devices, making them as better alternatives to mainstream telephone systems and services.
With the use of IP-based telephony, business organizations can upgrade and gradually shift from traditional telephony systems to the cost-effective and efficient IP-based telephone systems. End-users and business systems administrators can easily explore better alternatives since IP telephony systems operate under standard protocols.
IP Telephony Systems for Existing Business Databank and PBX Network
The existing PBX system of the company can be upgraded through the integration of IP telephony system into the current communication system. This enhancement in the communication infrastructure of the company can be implemented with minimal changes to the existing PBX system. Since the VoIP gateway generates standard telephone signals of T1/E1 lines and standard phones, it can be connected instantly to line cards of the PBX system.
The system administrator only needs to configure their current PBX system to accommodate the added line for VoIP system. The process of configuration is basically similar to the one normally followed when adding additional phone lines in the PBX system. The gateway is managed to provide services through a call server based on IP Centrex, ITSP or separate iPBX system.
Communication Servers for IP-Based Telephony
There are several types of communication servers that are used in IP-based telephony systems of business communication infrastructures. The typical configuration of these communication servers involves proxy servers that receive and handle call requests from existing IP telephones within the business communication infrastructure.
The administrator server, on the other hand, is responsible for the coordination of accounts within the communication system. The location server or unit manager’s primary function is the tracking of IP addresses that are assigned to the various communication units. The main functions of the gateway manager include the identification and coordination of communication through existing gateways. Finally, the system manager is responsible for the coordination of communication between the servers and programs that are present in the system.
Gateway Manager Applications
Gateway manager applications can be harnessed for the configuration and management of gateways that provide the link between the Session Initiation Protocol (SIP) network and other networks. The gateway manager has the information on the gateway configuration. These include the IP address, protocols, speech coders and access control information.
