Enterprises typically look at three communication links to the outside world.

• Leased-line voice traffic connections to all other branch offices;

• Voice gateway connecting the enterprise premises to the Public Network

• Leased-line for Internet access.

However, IP technology allows enterprises to invest in just a single communications pipe that will deliver voice and data communications to the enterprise desktop. The IP-PBX is an open-standards solution. This means that enterprises need not be tied down to one vendor for all subsequent enhancements to the solution. Moreover, an IP-based solution will drive other key services such as video conferencing, collaboration and other value-added options. These would include applications like directory integration, XML integration, application prioritizing calls received, calling-party name and number, calls received, missed calls and dialed calls, extension mobility, in an easy-to-program and easy-to-use platform. This solution also comes with ease to install and configure, and standard CAT-5 LAN cabling.

IP Benefits Amid Existing Regulatory Restrictions

• Cost Savings on Intra-office Long Distance Calls: Remember 70-80 per cent of the long distance calls are to your own offices outside the headquarter and vice versa

• Easy upgrades and Scalability: As the IP PBX technology relies on software, an IP-BPX can be upgraded (by adding new features) and scaled up easily to accommodate new users whenever there is a need.
