With Gamma SIP trunking from TMB, your business is connected to the Public Telephone Network (PTSN) using Voice over IP (VoIP) instead of traditional ISDN or analogue lines.
This delivers several cost saving and productivity benefits for your business:
- Reduce your telecoms expenditure
With calls charged on a per-user basis and simpler pricing structure for domestic and international calls, you can expect to significantly reduce your monthly spend and predict your bills with greater certainty. Save up to 50% on line rental and 25% on call costs.
- Improve collaboration with remote teams
With SIP trunking, you can connect your employees’ mobile devices via VoIP secure apps, so that everyone in your company can stay connected to your on-premise phone systems when out of the office.
- Scale-up with ease
SIP trunking allows you to add additional capacity to your infrastructure simply by connecting devices to your data connection, so off-site workers can be easily contacted via a single dedicated phone number and extension.
- Save money on hardware
With SIP trunking, you don’t need to invest vast sums in additional hardware every time you expand your telephony system. TMB can add services or additional phone lines for an affordable price and, because our contracts are designed to be flexible, altering your monthly commitment is an inexpensive and easy option.
- Improve reliability
Unlike conventional network connections, SIP trunking isn’t prone to the frustrating service interruptions that can occur when cables become damaged or equipment malfunctions. Should a problem arise with your VoIP connection, disaster recovery and business continuity solutions can be triggered to ensure that service is maintained and not a single call is lost.
