VoIP solutions for simple and scalable business communications

We understand that your business requires a reliable, integrated, and scalable communication solution to connect your teams, partners, and customers. Whether you are a growing business requiring a flexible voice solution without the need for day-to-day management, or an enterprise with multiple business locations on and off the island looking to converge your voice and data networks, we have a service that meets your business needs. 

SIP Trunks to keep your business in touch and in control

If your business requires a voice solution that is affordable, reliable, and scales easily, Session Initiation Protocol (SIP) Trunks* might be your answer.

SIP Trunks eliminate the physical connection to a phone company. There is no hardware, wiring, or circuit boxes to maintain to establish a connection. A SIP “trunk” is installed virtually over your business’s existing internet connection, therefore replacing the need for traditional analog phone lines.

GTA SIP Trunks let you implement VoIP technology for your business at your own pace. SIP Trunks can connect existing key systems to VoIP networks, allowing for a phased migration. Your business can manage your current infrastructure investments while migrating to SIP Trunks**.

At GTA, we are committed to serve your business with advanced networking technology. With SIP Trunks, your business can enjoy the following benefits:

Cost savings

SIP trunks allow organizations access to simple, understandable pricing. In addition, your business can make the most of your high-speed internet connection by using your IP-enabled networks for both voice and data.  By doing so, costs can be dramatically reduced through the reduction of the number of lines required.


Whatever your expansion needs are, SIP Trunks can support planned growth across multiple locations by combining your voice and data into a single network.


SIP Trunks allow for dynamic bandwidth allocation, ensuring that voice traffic is given the highest priority and calls always go through. There's no need to allocate space to fixed voice channels, as long as enough total bandwidth is available. That means SIP Trunks support highly efficient use of network resources, allocating bandwidth based on your business needs at the moment.


SIP Trunks can be quickly scaled up or down on a per-line basis so that you can easily meet peaks and troughs in demand.

* Wiring and hardware are the same as your internet/network connections. No additional wiring is required if network is in place.

** Requires SIP enabled PBX with Session Border Controller (SBC).
