VoIP Equipment and Solution Vendors

Whether you are a corporate or residential VoIP user, at one time or another, you have to give some attention to what equipment you are using, since they have a bearing on your VoIP experience. As the VoIP market has grown over the last decade, so has the number of vendors. There are dozens of these hardware manufacturers and solution vendors around, meaning better prices through competition, but also better quality and features. I have shortlisted some of the most popular and most evaluated vendors below.
