on RCA 25204 Telephone
Unable to use all 4 lines
Only the first 2 lines we can you on our 4 line system. Ive tried plugging in the other phone cord provided into lines 3 and 4 but there is no dial tone
While in middle of call, sound stopped. No dialtone, speaker or ringer on either line. Incoming call button lights up, but the line has not sound/volume. All lines working.
