CLI (Calling Line Identification) – How Caller ID Works in VoIP
Calling Line Identification (CLI) is the VoIP version of caller ID, showing who’s calling before you pick up. For UK SMEs, it saves time, builds trust, and projects professionalism. With the right VoIP provider, your business number appears clearly, not as “Unknown” or “Spam Likely,” helping you look credible and making sure the right calls get answered.
