I have a customer with a DK280, they want a second music source, I have found and installed a Page Industries PI-SMI unit, but it sucks, I have gone through two unit in 3 weeks, does anyone know of an alternative, this is a small office and upgrading them to a CTX is not going to happen. Any suggestions or ideas would be helpful

It's a RTCU 3A
16 phones
3 lines company a
2 lines company b

what do you mean by a second source
and what are u trying to do with it
are you trying different messages on different lines
or switch messages based on time of day,
day of week ?
