What I am seeing is that the DMS was collecting the digits properly before the cutover. Yet our migrated to setup is having trouble. We see missing digits in most cases or other oddities. It does appear the alarm panels are dialing within DTMF specs. Duration of the DTMF is approx 95 ms. A DTMF signal separated by a 150-200 ms pause.
-> Can you modify this timing to something longer? Like 250ms tone, 250ms space/delay? ---- Those are the exact questions I asked the fire alarm panel guy and it appears the answer is no once I got him through his 10 minute tirade it used to work on the DMS and other things he saw go wrong over his career. I also wanted to know if the alarm panel could manually dial a call like a pots line could and I never got a clear answer on that or documentation on the panel that I could study myself. So maybe the answer is no, maybe he never tried to do it, or he has no clue. ---- I get the feeling these alarm panels are quite old and based on the pictures I saw of a couple of them ancient. They have definitely been on the wall for 20 plus years along with that DMS switch sitting in our central office.
