I have Bell Canada's "Ident-a-call" on my home phone line, it gives you a 2nd number that rings on your primary line, but with a different ring pattern ("first" line gives normal ring, "2nd" line gives "ring-ring" like the British).  I let my "published" or first line be my fax machine, and the 2nd line be my voice number, keeps lots of telemarketers a bay :-)  Also lets you have a "fax line" and a "voice line" without having to pay for 2 phone lines, with the benefit that your voice line is unlisted (at no additional cost) and when you call out, the "first" number is the one that shows, so if companies use the line "you called us, you're an existing customer so we're exempt from Do Not Call lists" it doesn't interrupt your dinner :-)

This number just called in on my first (fax) number.

Callers from this number do not leave messages, hang up when phone answered, can not be reached by calling 1 (613) 688-5051.
When phoning back to this number:
Calling direct, the message is "this number is out of service.:
The number can not be reached by dialing 0-(613) 688-5051. Operator indicates the number could be a call center or other marketing service which is only equiped for outbound calls.
Also telephone booth service phones can not be reached by calling them back.

Thats a bit much to set up.
