What's the Best Way to Set Up Call Forwarding for a UK Business?

[trustcallpbx]

My business often misses important customer calls when staff members are unavailable. I'm considering TrustCall PBX and would like to know if its call forwarding feature is reliable. Can calls be forwarded to mobile phones, landlines, or a softphone application? I also need a dedicated UK phone number and an easy-to-manage PABX system. Looking forward to hearing about other users' experiences.
