Companies considering making the switch to VoIP business phone systems should take into consideration several factors when making the decision.
A properly built network is a great start. Since phone traffic will transport across the existing internal IP network within a business, maintaining or upgrading the IP wiring is important. Currently, scenarios exist for VoIP based PBX with Cat 5 E or Cat 6 wiring installed or present within the building. If these installations are not present it doesn’t necessarily mean that VoIP PBX is out of range for a business, but transmissions may drag without it.
The general difference between category 5e and category 6 is in the transmission performance, and extension of the available bandwidth from 100 MHz for category 5e to 200 MHz for category 6. This includes better insertion loss, near end crosstalk (NEXT), return loss, and equal level far end crosstalk (ELFEXT). These improvements provide a higher signal-to-noise ratio, allowing higher reliability for current applications and higher data rates for future applications. – See more at: http://www.broadbandutopia.com/caandcaco.html#sthash.c2C8l7Mn.dpuf
Knowing your current wiring status is clearly important. Working with your VoIP provider and your Internet Service Provider (ITSP) can prepare your business not only for the migration to VoIP business phone systems but also for future needs of data transmission in general.
Firewall and Router Status and Functionality
Second and very important is your Firewall/Router. 85% of VoIP problems are due to the Firewall/Router. Customers looking to transition to business grade VoIP solutions for telephony services will want to know what type of router they are using and what components/services their router capabilities are.
Organizations with business grade routers should find the transition to be seamless. Businesses using home consumer grade router systems should know that devices made for home use often layer additional services within the equipment which may cause conflicts with the VoIP system. In this case, discussing the equipment in advance with the providers involved will avoid problems during the transition.
VoIP firewalls offer a complete security package for your business. With a single firewall you can enhance your VoIP quality, protect your network, enabled remote access and deploy a secure wireless network for you and your visitors. Firewall settings are easily adjusted to pass the needed traffic in and out of the internet network allowing resolutions of any problems with service.
Internet service capacity and speed
Having a quality internet service provider who functions capacity and speed is necessary for businesses transitioning to VoIP business phone systems. The internet service provider bandwidth needs to be able to pass internet traffic quickly without interference as data increases on the system.
The backbone of the Internet is connected networks of high capacity communication lines. A dedicated connection to the Internet backbone that operates all the time, at the full capacity of the connection technology, is extremely expensive. Since end users rarely require 100% of the available bandwidth all the time, ISPs will purchase these expensive dedicated connections and use them to run multiple connections of various sizes to their end users. This is called “over-subscribing”, and is a technique used by the Internet Service Provider Industry to realize a profit margin when providing dedicated connectivity to consumer users. Over-subscription is usually based on a bandwidth ratio and typically ranges from 4:1 to 20:1 depending on the service being provided. Over-subscription may actually occur several times before it reaches the end user. See more at: http://www.ispgeeks.com/wild/modules.php?name=CapacityTest
The solution for businesses with the desire to employ VoIP business phone systems is to test up and down speeds offered by their existing internet service provider at the beginning of the discovery process. This testing is easily accomplished online and will benchmark the current actual speeds any business has access to.

Adjusting the priority of information transmission
As with any integrated system, the ability to devote a specific amount resource to a task within the system is critical to the efficiency. Businesses may not realize that their ITSP (IT service provider) can set priority to different types of transmissions within an internet connection, however this is entirely possible. Therefore, a business may work in advance with internal and external providers to dedicate a certain amount of transmission bandwidth to VoIP traffic. The dedication of resources properly sets the quality of service (QOS) to control what services get priority to and from the internet.
With proper settings incoming and outgoing calls remain crisp and clear, even when other internet office traffic increases.
Transitioning to VoIP business phone systems often make sense for many businesses both in cost and in ease of use with advanced features. Planning for the IT needs when devising a transition plan prevents headaches and problems in the roll-out phase of the new phone system.
