New phone. Looking forward to all the time I’ll save dialing by storing my contacts… on punch cards!

@dan Nice. Now I'm curious if my VOIP gateway understands rotary pulses rather than touch tones. Hmm.

@dwallach You can definitely find ones that do! (e.g., most of the Grandstream models)

@dan @dwallach My Grandstream HT802 doesn't seem to; at least when I plug in a pulse-dial handset and press a digit it continues to give me a dial tone whereas as when I use a slightly less-ancient DTMF handset the dial tone goes away on the first digit press.

@edavies @dan @dwallach on the HT802, it's an explicitly supported feature — you just have to enable it in settings. in the FXS PORT1 (or 2) page:

@dan @dwallach some systems do. It is tedious, though, because the system needs a really steady pulse. So you had to be really careful dialing in a steady, slow and monotonous way.

I did use my rotary phone together with a fritz Box up until about 2008, but then I gave up because it was really a hassle to dial longer numbers, with a lot of 9 or 0 in it.
