Running both main and aux transmitters is unlikely to be a long term problem. The reason it caused interference into the phone system is that phase cancellation created large amounts of AM in the signal. That AM also severely degrades reception of the station, which should be noticed by a fair number of people.
It is very poor technical practice to build an FM station in such a way that two transmitters and antennas can be on the air at the same time. It can be prevented by interlocks, or by having the remote control alarm for the condition. That a transmitter changed its state following a power interruption is unusual and needs to be examined as well. In other words, this isn't a routine problem.
