@aaronpk GrandStream HT802 works *great* for pulse dialing (optional mode). Have multiple rotary phones in operation using it. https://www.grandstream.com/products/gateways-and-atas/analog-telephone-adaptors/product/ht802
I have thought about using a sidecar (wired) or handheld DTMF (acoustical) generator - they used to have such things. havn't done so yet
@aaronpk so a rotary encoder that turns it into dtmf. nice
no, i usually just get the real thing at thrift stores etc. main rotary looks about like this
beware if you turn on pulse, then bouncing the hook will dial (working as designed)
