RCF FAQs
BT Remote Call Forwarding FAQs
Common questions about RCF / Exchange-Specific Numbers and porting. Don't see yours? Let's talk.
What's the difference between RCF and a virtual landline?+
Both forward inbound calls. RCF (Remote Call Forwarding) is a legacy BT product where the number is tied to a specific exchange. A virtual landline lives in the cloud, same effect for the caller, far more flexible to manage and significantly cheaper to run.
Should I keep my existing BT RCF?+
Usually yes. Established RCFs have call history, search ranking and brand value beyond the number itself. We strongly recommend porting rather than replacing, we'll handle the port and the savings start straight away.
How much can I save by porting?+
Most BT RCF customers save several hundred pounds a year per number. Send us your latest bill and we'll quote a like-for-like cost within 24 working hours.
Will calls drop during the port?+
No. We coordinate the port with the losing provider so there's no break in service. Calls keep ringing through during the handover.
Can I have RCF numbers in multiple towns?+
Yes, many of our customers run RCF numbers across several towns, cities or even countries. The Value plan covers multiple numbers under a fixed monthly fee.
