Dispatcher reported a landing gear indicating system failure caused inaccurate gear position reports. The flight crew communicated with Maintenance and Dispatch; but were unable to resolve the problem and continued to the destination airport.

Narrative

Pilot called via radio. On descent at 500 feet they received notification that was a conflict of indications on if their landing gear was actually down. They had all green on landing gear down but the notification indicated that maybe the gear was not down. They did not receive an EICAS Message so there was not a specific QRH procedure to follow. The warning they got was along the lines of 'too low gear' with a proximity warning. They circled at 4;000 feet while on call w/ Dispatch and Maintenance. Initial call XA03z Maintenance added XA07z. Pilot attempted to get a hold of XA18z no luck. Tried twice. The plane's computer shot out a warning that was giving the crew mixed signals on if the landing gear was actually down but did not give an EICAS message. There was not a specific QRH procedure to accomplish for the problem since there was no EICAS message. So the crew called dispatched and Maintenance got involved on trouble shooting the problem as well. If Boeing perhaps had a specific EICAS message for this situation to direct the crews.
