In recent years, web video conferencing has moved from a tech curiosity and gamer tool to a nearly ubiquitous component of most business telecommunications toolboxes. A key reason is an increase in the average Internet bandwidth most businesses enjoy, which has the effect of smoothing video conferencing sessions to nearly the same reliability and quality as voice calls where once buffering and sudden disconnects were the norm. Another reason is rising business travel costs, where establishing a quick video call between multiple participants can have the same benefits of flying those people to a central location to meet face to face. But another reason for its popularity is that the combination of video conferencing, online collaboration software, and smart meeting room hardware, like the Microsoft Surface Hub, can provide a data-optimized meeting environment you simply can't get any other way.
Other features I look at include the number of participants allowed on a call and the number of video feeds allowed simultaneously. The most generous is Adobe Connect, which is unlimited, but some offer as few as four participants at a time. Consider how important this is to your company. Most services let you record meetings, and a few let you edit the recording right within the software. These recorded meetings can then be used for your records or as webinars for anyone who missed the meeting or for new employees.
