Do your homework on vendors and phone brands. There are many SIP phone vendors, and if you view them as commodities, it will be difficult to tell them apart.
From personal offices all the way to large-scale training rooms, collaboration is an essential part of business. Maybe you need a solution that can transition from a personal workspace device into a scalable conference phone. With any good conference phone, you can have conference calls that are as productive as face-to-face meetings.
SIP phones may seem like an afterthought, especially if you view telephony as a commodity service that “just works.” But choosing the right SIP phones has a direct bearing on VoIP’s value, especially among end-users.
At a minimum, you want comparable features to your legacy phones. But with SIP phones, you should expect more. Core features enable a good everyday end-user VoIP experience. Keep in mind, not all SIP phones are created equal.
