Business VoIP phone system on 3CX, managed with your IT

3CX is a business VoIP phone system: software that runs your company’s phone lines over the internet instead of traditional phone wiring. It handles extensions, call menus, queues, voicemail and mobile apps. Having it managed means Nexxo sets it up, keeps it updated and secure, and makes changes for you. You do not need someone in the office who understands phone systems, and call problems are handled by the same team that runs your network.

Teams is great for internal chats and meetings, but many businesses still need a real phone number, a call menu, queues and a reliable way to answer clients who call in. 3CX handles that side. It can be integrated with Microsoft Teams, so staff can keep working where they are comfortable while calls follow your business rules. We will help you decide what makes sense for your team.

In most cases, yes. Moving a number to a new provider is called number porting. We coordinate it with your SIP trunk provider, the company that connects your phone system to the public phone network, and plan the switch so calls keep reaching you. Porting timelines depend on the carriers involved, so we start early and confirm the date with you before anything changes.

The main factors are the number of users and extensions, whether 3CX is hosted in the cloud or on a server in your office, the number of desk phones you need, your phone lines and calling plan with your SIP trunk provider, the number of sites, and features like call recording or integrations. The level of support also plays a role. We start with a review so the proposal fits how you actually use the phone.

We first document your current setup: numbers, extensions, greetings and who answers what. We then build your 3CX system in parallel, set up phones and apps, and test with your team before moving any numbers. The final switch is scheduled with you, often outside business hours, so clients keep reaching you. Staff get a short walkthrough of the basics, and we stay close in the first days for adjustments.

Recordings and voicemails often contain personal information, so Québec’s Law 25 applies to them like any other data. In practice, that means informing callers when calls are recorded, keeping recordings only as long as needed, limiting who can listen to them and knowing where they are stored. Nexxo configures 3CX to support these obligations and documents the setup. It is not legal advice, and we work with your privacy officer.

Call quality depends mostly on your network. Choppy or one-way audio usually comes from a busy internet connection, a poorly configured firewall or weak Wi-Fi. Because Nexxo manages those too, we configure quality of service so voice traffic gets priority, check your bandwidth and fix the network side. If a problem appears later, one team investigates the whole path instead of two providers pointing at each other.

We keep your system updated and secure, monitor it, and handle moves, additions and changes: new employees, departures, new greetings, holiday hours or a new queue. If a phone stops working or calls sound poor, you contact our support team, 24/7, and we troubleshoot the phone, the network and the firewall together. You have one point of contact for your phones and the rest of your IT.
