From an infrastructure standpoint, before placing a VoIP system inspect your network to see if it’s suitable for high-quality voice packets.

• First, test your current internet bandwidth to ensure it is sufficient to support multiple simultaneous calls.

• You may also need to upgrade your routers or switches so they support prioritization of traffic - in this case VoIP - with some Quality of Service (QoS) settings.

• Check network stability to avoid call drops or delays.

A strong connection makes for clear VoIP calls.

2. Choose the Right VoIP Provider

Companies such as Wondercomm also provide a range of packages which are custom-made for small and medium-sized businesses.

3. Select Compatible Devices and Hardware

Even with a cloud solution, you’re still reliant on good hardware for performance.

• Decide whether your team will use desk phones, softphones or mobile apps.

• Make sure the headsets and microphones are up to quality standards to eliminate as much background noise as possible.

• Manage compatibility between physical devices and cloud services In hybrid configurations, ensure that physical devices work with cloud service.

The right hardware offers staff and clients a seamless, professional calling experience.

VoIP systems deal with sensitive business and customer information, so security is crucial.

• Control admin access to approved users and track use.

These steps help keep your business data safe and compliant.
