Before introducing this solution, let’s see the differences between the IP Telephony and Traditional Telephony system.

	IP Telephony	Traditional Telephony
Expense	Cheaper: Using the existing WLAN & LAN cabling.	Expensive: Monthly fee and extra expense of IDD
Mobility	Move the IP Phone anywhere you wish	Need to call telecom person to set up in specific locations
Extension Line	Implement personal extension lines with several IP Phone	The more staff the company has, the more quantity of telephone they need
Management of voice messages	Recognize the voice messages and e-mail it to the specific person.	Cannot recognize the messages and it relies on manual operation.
Functions	A wide range of functions, like web management & hotline-setup etc.	Limited function which only involves simplex communication.

When comparing to traditional telephony which uses circuit switched network dedicating end-to-end bandwidth to each individual connection for the duration of the call, IP telephony is much efficient as it transmits the audio signals over small packets and sent it across the packet-based infrastructure, such as a data network or the internet, to their destination. Under this innovative system, users take full advantages of resource usage because they can obtain two-way telephony with multiple conversations sharing common bandwidth.

Cost-saving

• Set up easily as it makes use of the existing LAN cable for connection instead of requiring the additional installation which helps lowering the cost of hardware connection
• One cable for all applications, including voice, data and video; no need to install different cables

High Mobility

• With the wireless implementation, you can connect with the IP phone anywhere as you wish
• Provide better remote support for the workers who usually spend their time away from their office, but still need access to the same network no matter where they are; the converged voice and data networks makes it easier for companies to arrange duties to these remote workers

Centralized Management

• Eliminating the need for smaller key systems for individual branch offices as it gives enterprises the capability to centralize their voice and data network on headquarter or regional basis, so the investment in equipment can be reduced

High-quality Communication

• Effectively eliminate latency and jitter by high-performance network

Numerous Functions

• Web management
• Setup hotline to handle special inquiry/event
• Integrate voicemail and auto-attendant feature
• E-mail Alert
• Call center
• Soft Phone
• Call Detail Reports
• Call Park & Page
• Plug and Play USB Phone
• Ring group and Hunt group
