I am currently using Nitsuko Onyx 88263B, 88260B, 88261B, and 88361 model telephones. Some phones need to be replaced since our office have been using them for about 10 years. There is no problem with the wiring, just the actual phones with hard to press bottons or speaker not working anymore.
If I purchase Nitsuko Onyx 88363, will that be interchangeable or compatible to any or all of my current Onyx phones? Please help! Thank You.
yes , they will all work together
