Dial Pulse to Touchtone DTMF Converters

Created by: jht2,Last modification on Fri 19 of Jun, 2009 [01:57 UTC] by oldphoneguy
Many VOIP devices with FXS ports do not support traditional rotary dial phones.
One possible solution (untested) is a Dial pulse to DTMF (Touchtone) converter between the rotary dial phone and the VOIP FXS port

Example:

  • Dial Pulse Phone <-----> Pulse to DTMF converter <-----> VOIP FXS port on a SIP ATA

Some possible choices:

Known to work, tested:
  • Dialgizmo Pulse to Tone Converter - Approx $40
    • Will convert rotary pulse dialing to DTMF tone. Allows dialing of * and #, speed dial and LNR
    • Works well with the lower line voltages found on some ATA FXS ports
    • Source: http://www.dialgizmo.com
  • Oldphoneworks LPT-310 Pulse to Tone Converter - $39.95
  • Rotatone Pulse to Tone Converter - $39.95
    • Designed for installation within a Rotary dial telephone. Some technical expertise required for installation. Adds *, #, Speed Dial, Last Number Redial and Hotline functionality to a rotary phone. Installation services available. Swedish and New Zealand versions available. http://www.rotatone.com

333TelSoft

TelSoft has sold their pulse to tone converter product line to Oldphoneworks. The LPT-310 is a great unit that flawlessly converts rotary dial pulses to DTMF tones. Unlike it's predecessor the LPT-300, the LPT-310 filters the dial pulses from the output to prevent the dialing of double digits. At $39.95 it's a great value!

333UTStarCom Ian-02ex works with rotary!

I have an UTStarCom ian-02ex that was originally from Lingo. I discovered by accident that it does rotary dialing with no problems. I will be connecting it permanently to a 1960s vintage rotary wall phone soon.

333TelSoft Converters

I bought one of these - the carriage outside the US exceeds the cost of the unit - BEWARE they only send by UPS - cost US$53.95 for the unit plus US$56.00 carriage and the UK Customs charge import tax on the total price !!

They also produce versions for use with the New Zealand reverse pulse dial and another for the Swedish 'reverse' pulse dial.

333Programming details

Can anyone provide programming suggestions for the Mitel Smart-1 to act as a passthrough pulse to DTMF converter? The programmingappears quite complex.

Mitel Smart-1 dialer = $18?

Now the website says $35.95, surely it hasn't gone up THAT much in a year

333What works and what doesn't.....

by MrKenmore, Saturday 02 of July, 2005 [02:54:03 UTC]
I have done extensive experimentation on this subject. I have Vonage and the Linksys RT31P2 adapter. The pulse to tone converter from Sandman does not work. The Mitel Smart-1 does indeed work. It does take some programming and an RS232 cable will help tremendously. All programming can be done through hyperterminal. Be advised that the downloadable manual from dialerbuddy website is for a later model. The manual is 2000 and the software on the machine I received is 1991. So some things are different. You can also do a whole bunch of other things with the Mitel. Definitely worth it. Good luck and keep those rotariy phones alive.
