The type of telephony service you need would depend on the objectives and infrastructure of your business.

SIP Trunks offer a more flexible and lower-cost alternative to ISDN for inbound and outbound voice calls. SIP Trunking is a standards-based replacement for traditional ISDN. It connects your PBX to the PSTN via broadband and Ethernet. Any business with a PBX can switch to our SIP trunking service and immediately benefit from a more flexible, less expensive and more resilient phone service. Our SIP trunks work seamlessly with each of the leading IP PBX brands in the UK market. Find out more here >

If you don’t already have a PBX in your organisation, or your current hardware is no longer meeting your business needs, then hosted telephony is ideal for you. OnlineUC is our hosted business telephone service that resides in the cloud rather than your office. It provides an extensive range of fixed and mobile telephony capabilities accessed through an easy-to-use web portal. The service allows you, the administrator, to easily manage your environment whilst enabling your employees to maximise their productivity. Find out more here >

We offer a number of services to overlay on top of your telephone line or SIP service to ensure you never miss a call. You could consider activating voicemail services, call forwarding to point your calls to your mobile, we can even bar calls from withheld number callers to ensure your lines are not tied up with nuisance calls.
You could consider purchasing an 0800 or 03 non-geographic number which you can point to your local number, giving you a more professional, nationwide image. We can also provide services over the top of this number such as call queuing, Integrated Voice Response (IVR) and various other call distributing options to give you additional inbound call support.
While ISDN remains a supported, reliable and robust telephony solution, you are limited to local telephone numbers and if you are considering an installation, costs can be quite high in comparison to cloud hosted SIP products. Daisy can provide you with the right connectivity to support SIP telephone lines, enabling you to move to VoIP technology whilst still retaining all the features of ISDN.

Whether you have chosen ISDN or SIP, we can ensure that no matter what happens, your lines are always available. For ISDN we recommend Site Assurance which has two options. Option 1, when invoked this will point all calls to another number. Option 2, which is more robust, allows you to have a standby ISDN circuit which you can activate on request.For SIP, we can offer standby endpoints which will automatically activate and process calls if your main SIP Trunk is unable to pass these calls to your site. We also offer active additional endpoints such as loadshare, to evenly distribute your calls or you can also set up diverse routing plans via the online SIP portal. You can also set up your main contact numbers as an inbound number to overlay on top of your SIP services, as well as using the online portal to set up predefined call routing plans to re-direct calls to alternative numbers or sites using the portal or app.

Using Daisy’s MyAccount portal you can set up alerts on numbers to monitor your spend.
You can choose to add Daisy Fraud Guardian, a service provided to monitor, alert and protect you against unnecessary financial exposure to telecoms fraud. Daisy receives call data records from its suppliers 24/7/365 at regular intervals throughout the day. The platform collects and imports this information and generates automated alerts which are analysed by our dedicated Fraud Team 24/7/365. In addition to call pattern analysis the team shall be entitled (but not obliged) to automatically suspend any line that reaches or exceeds a daily spend limit of £500, or any other daily spend limit for that line which may otherwise be specified on the order form.

“Today, to manage the built environment effectively, you have to digitise it in some way. We’re training drone pilots to give us digital images of areas… putting GoPro cameras on the front of trains to survey lines. It’s becoming much more of a digital environment. For us, it’s about using tools to get a better view or control of scope and scale.”
