Here is the problem we switched phone systems from a Partner ACS to a Merlin Legend.Our current system is a legend R7 V14.2.Our bells worked before on our partner system.i understand that system is analog/digital to where our new system is solid digital other than the 2 analog cards we have installed in it.We have some SAA's and i have tried them but when i get them hooked up and i turn the switch to the on position it sucks all the power out of the phone.Throughout our main plant we still have the mls telephones but we have them plugged into our ETR card so they work.Thos phones are the ones that the bells are hooked to.What can i do to make these bells work without running more wires.
