Business phone systems: frequently asked questions
Which business phone system is best for a small UK company?
It depends on your user count, call volumes, budget, integrations and support needs. Hosted VoIP is often worth comparing with 3CX, Gamma Horizon and Teams Phone.
Can we keep our existing business telephone numbers?
Often yes, subject to number ownership, porting eligibility and the existing provider's processes. We plan the changeover before confirming dates.
Can Gamma Horizon or Webex replace our current phones?
They may be suitable, depending on the service, handset compatibility, collaboration requirements and licensing. Horizon with Webex and other Webex services should be compared separately.
Do all phone systems include AI, call recording and CRM integration?
No. Features differ between products, licences and optional integrations. We confirm the exact requirements and available package before quoting.
What internet connection do we need for VoIP?
Reliable connectivity with sufficient capacity, suitable network configuration and a resilience plan is important. We assess your broadband or leased line alongside the phone system.
How much does a business phone system cost?
Costs depend on users, licences, handsets, calling, installation, support and contract terms. Request a tailored quote so the comparison includes your actual requirements.
