OK, so now my system is working.... except for the 202b.... sort of.... when the line is picked up, the light works, when put on hold, the light flashes.... but when a call comes in....no light, and the R relay only closes when a ring pulse is detected for the first few rings and then goes steady until the line is dropped... what wiring do I need to check to remedy this.... or is it because its connected to a VOIP ATA controller.... I had a rough time connecting the control leads (TO, LK, HA, C) because the cross reference gets confusing... it seems to be right now, but not sure...the schematics are hard to read at times because the terminals are almost the same numbers, etc. I wish these papers were easier to read...
