Frequently Asked Questions
Q: Does the CT-CID803 PLUS call blocker work with any landline phone?
A: Yes, the CT-CID803 PLUS is compatible with most standard landline telephones. However, it requires that your telephone provider has Caller ID service enabled on your line. Without Caller ID service, all incoming calls will be rejected automatically.
Q: How many numbers can I block with this call blocker?
A: The device supports a large blacklist of up to 1,000–1,500 individual numbers. You can also block entire area codes or number prefixes, with up to 10 area code groups supported.
Q: Will blocked callers know their call was blocked?
A: When set to 0-ring mode, the blocked call is silently rejected — the phone never rings and the caller may hear a busy tone or standard disconnect message. With 1-ring mode, your phone rings once before rejecting the call.
Q: Can I block calls that show "Unknown" or "No Caller ID"?
A: Yes! The CT-CID803 PLUS has a dedicated Block No Caller ID feature. When enabled, all anonymous or withheld-number calls will be automatically rejected — a great way to stop spam callers who hide their number.
