A 01638 number for the phone system you choose

A professional 01638 number can give callers a familiar point of contact while your team answers from an office, home, mobile or cloud phone system. UKDDI supports inbound VoIP, SIP trunking, hosted business phone systems, 3CX-compatible routing and straightforward call forwarding. Live availability and pricing are shown on this page.

3CX and SIP trunk

Route inbound calls to a compatible 3CX deployment, session border controller, IP-PBX or other SIP platform using registration or IP-authenticated delivery.

Hosted VoIP phone system

Use the number with a hosted SIP extension, cloud phone system or cloud voice service and add a compatible desk or cordless handset.

Landline or mobile divert

Forward the virtual number to an existing UK landline or mobile when you need a simple business call-forwarding service without new hardware.

Keep your public number

Start with call diversion and move to SIP or a hosted phone system later, subject to provisioning and service compatibility.
