  • Does Gamma allow us to build call plans?

    Using our Inbound product, you can build call plans according to your operating hours and modify them instantly with your changing business needs. Schedule call routing in advance according to your business hours and call handling preferences, and use call divert options to maximise your call handling potential, providing an improved service to customers.

  • How can we retain phone access in an emergency?

    Deploy Gamma’s SIP trunking to handle emergencies such as office closure due to flooding, etc. SIP is disaster recovery/business continuity-ready, allowing you to reroute calls to an alternative location quickly and easily, meaning you never miss a call.

  • What if we are moving office?

    Number flexibility with SIP trunking means that you can keep your existing number, even when moving out of the area. This saves you costs on printed company literature and stationery while maintaining the perception that you still have a presence in the area you have moved from.

  • What are the financial benefits?

    There is no up-front spend on hardware or software plus hosted telephony means no costly PBX maintenance or upgrades as we are responsible for the hardware and software, including system upgrades. You can also access low-cost and free IP calling.

  • Does quality suffer compared to fixed telephony?

    Start with a proper business network, add quality of service and SLAs and your staff and customers will be unable to tell that they’re using a cloud-based phone system rather than fixed line.

  • What is hosted telephony?

    A telephone system that resides in the cloud rather than in your office. Users access the system through a standard IP handset or a softphone – a screen-based virtual phone with headset. Calls are made/received over a broadband connection to the Gamma network. From there they are routed to PSTN fixed and mobile devices.
