How much does it cost to set up a VOIP phone system?
Choosing the Right Telecommunication System: Traditional PBX vs. VOIP
Any modern company setting up a new office requires a reliable telecommunication system to handle its phone communications. Business owners and IT decision-makers typically face two main options:
Deploying a traditional PBX (Private Branch Exchange) system
Implementing a VOIP (Voice over IP) solution
Due to the wide range of advanced features offered by VOIP systems—such as internet-based calling, interactive voice response (IVR), call queuing, voicemail, and many others—many organizations are leaning toward IP-based telephony solutions.
Our Approach
In this section, we aim to provide a comparative cost analysis to help you gain a clearer understanding of what is involved in setting up a VOIP system. This comparison will cover key aspects such as:
Number of users
Call quality
Available features
Overall setup costs
While there are cheaper alternatives on the market, this comparison focuses only on products that meet our minimum quality standards.
🔍 Note:
For example, the Atcom brand offers affordable IP phones that meet our basic quality criteria and are suitable for entry-level VOIP deployments. However, some of their low-cost IP PBX systems do not meet performance and reliability standards, and as such, are not recommended.

Additional Notes on VOIP Implementation
You can freely mix and match IP phones and PBX systems across different rows of the table based on your specific needs and preferences. This table is designed to provide a general overview of VOIP project costs, and does not include items such as executive phones or network infrastructure (cabling, switches, etc.).
In more advanced projects involving dedicated servers, additional features such as:
Software-based fax
CRM (Customer Relationship Management) integration
Custom development and programmable call flows
can also be implemented, offering greater flexibility and functionality.
That said, it’s important to strike a balance between available features and the client’s budget and actual needs. What remains clear is that VOIP systems offer unmatched potential in terms of:
Advanced telephony features
Long-term cost savings
Enhanced business communication
Strengthening your company’s professional image
Deploying a modern VOIP phone system can become a strategic asset for organizations seeking smarter, scalable, and future-ready communication solutions.
