IP Telephony
How reliable is your network?

 When voice and data converge, the network must be more dependable than ever.

 In the telephony world, phone systems are engineered to operate with 99.999% reliability. Because voice communication is real-time and is quite often used in mission critical environments, failure is not an option. Traditional data networks are more forgiving, allowing for lost packets, delays and failures. How many times have you been forced to have a coffee break while the techs reboot the servers?

 As we begin to converge voice and data into the same environment using a common physical infrastructure, we need to reassess how we reliably manage our data. Is 99% reliability good enough? If we have a system running 99% of the year, that equates to more than 3½ days of down time.

 To ensure that your network is ready for IP Telephony, you need to carefully assess your network design, usage, user groups and technologies. Doing your homework before introducing voice on the network will ensure that your environment will support the additional applications and provide the up-time that you need for your business.
