Toll-free number monitoring that confirms callers get through
Toll-free numbers pass through more hands than local lines: a responsible organization, a carrier, and often a routing service. When one link breaks, callers hear an error you never see. Line Canary calls your 800, 888, 877, or other toll-free number on a schedule and tells you when it stops connecting properly.
Problems a scheduled call catches
Porting and carrier changes
Moving a toll-free number between providers is a common time for routing to break, sometimes only for callers on certain networks.
Numbers printed everywhere
Toll-free numbers live on packaging, trucks, and ads that can’t be updated quickly. When the number fails, every one of those becomes a dead end.
Marketing lines nobody watches
Campaign-specific numbers are set up once and forgotten, while the ads keep running.

What Line Canary heard
We’re sorry, your call cannot be completed as dialed. Please check the number and dial again.

Checks that catch carrier-level failures
Because Line Canary places a real call and transcribes it, it catches failures that happen before your phone system answers, such as intercept messages, fast busy signals, and calls that never connect.
One line per number or per path
Monitor each toll-free number you publish, or several paths through the same number’s menu with IVR testing. Each line has its own schedule, history, and alert contacts.
