I'm attempting to get message waiting lamps to work across a Qsig link. The SX200 ICP is the Qsig slave to a Tadiran PBX( Qsig master) which is conected to a Active Voice voicemail system. The basic Qsig features work, caller ID, name & number, voicemail login, etc.. but I can't get the message waiting lamps to work on the SX200icp sets.I followed the e-doc's when setting up the new link.
