Hah! Circa 1990-something you could go to Radioshack and buy a tone
generator. You would hold it up to the mouthpiece of your rotary phone
and push the buttons on it to make DTMF tones so you could use IVR menus.
....I never used one for it's intended purpose, but I bought one because
you could modify the asterisk key to create the 5c tone for a payphone.
Tap it 5 times to pretend you put a quarter in. The whole idea was
ridiculous because I spent more money on that project than I ever spent
on payphones.

I wouldn’t bring up rotary dial, they will look to see if your horse

mention it doesn’t support party line.
Anyone trying to use a non-DTMF capable phone will have trouble using
voicemail and IVR anyway.
If you really need to connect your antique phone:

*Subject:* [AFMUG] voip inadequacies
I am compiling a list of sip/voip issues I have run into over the
years. I am going to get beaten up by some bureaucrats tomorrow
morning and I want to have a list to defuse them before the oral part
of the proceedings start.
I am going to say that ATA/SIP/VOIP is not suitable for the following:
Fax Machines (don’t even get me started on this, tried to do a
doctor’s office and pharmacy once....)
TDD The teminal that deaf people use. Does anyone know if a TDD will
work on a garden variety ATA? I don’t have one I can test with.
Dial up modems....
Fire Alarm control panels (the monitoring companies refuse to even
hook it up if you tell them it is VOIP).
Burglar Alarms .... ditto
I wonder about heart monitors that you wear and have the results
phoned in.
Dial phones. I have never tried to use a pulse dial phone on an
ATA/SIP unit. I wonder if it would work.
Any others?
