If you're trying to call or fax a hotel to confirm a reservation and the number just rings and rings just hang up and dial the same number again. Here on Ambergris for the last few weeks people have been losing a LOT of phone calls because of a problem with the BTL exchange...the caller thinks the phone is ringing but in reality the phone is silent unless the caller rings the SAME number again. This happens on about 25% of the calls made to AC numbers.

BTL have assured me they are working on fixing the problem.
