There are, for example, industry-specific systems for hotels, call centers, and hospitals. Though most small businesses will not be looking for specialized industry systems, they often do have special hardware requirements. Some need wireless handsets that can operate outdoors or a long distance away from a base station. Others don't use handsets, but instead require wireless headsets with long battery life. Knowing what is needed before you begin will make the selection process easier.

VoIP security. As touched on above, the underlying protocol for VoIP is SIP and it wasn't built with security in mind. This means hackers are taking advantage of several new attack vectors. One example is a denial of service (DoS) attack specifically on a phone service rather than the network as a whole. This will garble or drop your service because it results in your connection quality degrading, heavy latency, and system crashes. Caller ID spoofing is also becoming more common. This amounts to a phishing attack using a phone rather than an email. By calling workers with a caller ID that looks like it's coming from inside the company, hackers are able to get employees to cough up all kinds of sensitive information because they think they can trust the person at the other end of the call.
On-premise or hosted PBX: This isn't a choice all businesses will face. Small analog phone systems usually come with a simple hardware PBX that's kept on-site. And medium and large businesses often want the control of an on-site PBX, but they also have the IT budgets needed to maintain them.
