Sounds like it could be a mechanical relay clicking. Is it actually coming from the speaker?

- alnwlsn 2y agoAccording to this [0] schematic, there is a relay present. Looks like it's job is to be the hook switch for the phone. The recording sounds like the characteristic ping of a reed relay to me, so it seems like it's hanging up and then going off hook again every 1.2 seconds. Not sure why it would be doing this - maybe it's trying to get a dial tone? Is it smart enough for that? 0 - https://www.zimmers.net/anonftp/pub/cbm/schematics/misc/1670-cr-modem-schematics.jpg https://www.zimmers.net/anonftp/pub/cbm/schematics/misc/1670...
