Why VoIP, why now? |
In the last five years, advances in networking technologies
have enabled convergence of telephony as an application on
IP networks. Enterprises have taken advantage of IP
telephony for a variety of business-critical benefits:
|
• Cost savings due to toll bypass and bandwidth consolidation.
• Simplified voice network engineering
• Reduced legacy PBX equipment requirements
• Consolidation of wiring infrastructures for voice and data via Ethernet
• Consolidation of directory and other infrastructure data for voice and data
• Natural mobility by leveraging inherent IP network capabilities such as DHCP and DNS
• Appearances on multiple phones to simplify lives of users who work from different locations
including office, conference rooms, remote locations, and home
• Client devices such as IP phones that are more user-friendly, feature-rich, and standardsbased
than their TDM equivalents
• Availability of new applications and services resulting from increased speed-to-market
product development
• Integration with applications due to web-friendly interfaces supported by IP telephony
protocols such as SIP
