All incoming calls, including Fax & Modem, ring on the telephone. Whats wrong?
Either you have lost power to the STICK (check that LED is glowing red) or the program options in the STICK may have gotten “scrambled” by a power glitch causing the STICK not to answer. In the first case, confirm your power source. In the second case, see Operations Manual Sections 2 & 3 and reset the options to Factory Presets, then re-program any custom settings you may have had, i. e. CID ring to answer delay.
