VoIP Phone Systems
20+ years of experience with VoIP (Voice over IP) phone systems in Greece, for businesses large and small.
VoIP phone systems use your business's existing network (LAN), have the lowest maintenance and expansion cost, are easy to configure, and require no rewiring when you move devices — features that make them clearly superior to conventional phone systems.
A serviceTag specialist will discuss your business's needs with you, with an eye on both the present and the future. We handle every stage of the project — design, installation, programming, staff training and technical support — so your phone system runs seamlessly. We also take on maintenance or upgrades of an existing Asterisk-based VoIP system.

VoIP phone system FAQ
What is a phone system?
Known as a PBX (Private Branch Exchange), a phone system acts as a company's central call switchboard, handling internal calls and the gateway to the outside world.
Do they require special lines from providers?
Not necessarily. VoIP accounts replace analog or ISDN lines via SIP trunk channels, with an easy, quick setup. PSTN, ISDN BRI/PRI and mobile lines are also supported where needed.
Is call quality worse than on classic phone systems?
No. Nearly all calls today, with or without a phone system, already travel over the Internet. With the right equipment and provider, a VoIP phone system's call quality is excellent.
Can it connect with CRM or ERP applications?
Yes. Many CRM/ERP systems can route calls through Asterisk, linking call logs to customer records and opening the customer's file automatically when they call. Implementation requires programming, which we handle.
