Frequently Asked Questions
Can we keep our existing phone numbers when we move to HTL?
Yes. In most cases we can port your existing numbers to the new system so clients and suppliers continue to dial the same details.
Do you only support cloud phone systems?
No. We support both cloud and on-premises systems, including Avaya and 3CX, and we’ll recommend the model that best fits your size, budget and existing setup.
How do telecom services integrate with Microsoft 365 and Teams?
We can connect your telephony to Microsoft 365 so users can make and receive calls from Teams, use softphones, and see presence information alongside email and chat.
What happens if our Internet goes down – do we lose all calls?
We’ll design a resilience plan – for example, failover to backup lines, mobile diverts, or a second Internet connection – often tied into your IT Service Continuity plan.
Can you help us migrate from an old PBX?
Yes. We regularly move clients from legacy systems to modern cloud or hybrid solutions, planning the cutover to minimise downtime and user disruption.
