What is VoIP?


VoIP Explained

VoIP or Voice Over Internet Protocol, provides an alternative way of making phone calls using the internet rather than traditional telephone lines. It uses cutting edge IP technology to route your business’s voice calls over IP networks at lower call rates creating cost savings on calls.

VoIP has had a mixed reception by businesses due to poor implementation of VoIP solutions over the past 15 years. Business grade VoIP is not to be confused with your standard, free VoIP offerings such as Skype and Whatsapp calling. Business grade VoIP offers better quality call clarity and functionality than the traditional incumbent copper line legacy infrastructure while typically reducing a business’s overall telecom costs.

VoIP allows for many additional benefits outside of the typical voice call rate savings, including free interbranch calling and seamless transferring of calls between national branches.  

United Telecoms has a strategic business relationship with multiple Voice and data providers allowing us to offer you the full suite of VoIP products. Our expert account managers handle all dealings and integration of the connectivity into your current or new PABX.

Our solutions are designed for stable, high-quality business grade voice and can be customized to suit any make or model of PBX and instantly reduce call costs.
