One possible solution (untested) is a Dial pulse to DTMF (Touchtone) converter between the rotary dial phone and the VOIP FXS port
Example:
Some possible choices:
- TelSoft VOIP Pulse To Tone Adapter (Plug and Play)
- Source: http://telsoftdirect.com/index.asp?PageAction=VIEWPROD&ProdID=19 Approx $54
- Mitel Smart-1 dialer (requires programming)
- Source: http://www.dialerbuddy.com/mitel.htm Approx $36
- Sandman PULSE TO TONE CONVERTER
- Source: http://www.sandman.com/digit.html Approx $45
- Panasonic KX-TA624 hybrid key system
- Factory-default configuration will convert pulse dialing on an extension to DTMF on an outgoing CO port. Unit supports 10 or 20 pps dials.
- Note: Early model KX-TA624 units tend to spontaneously reboot when ringing old-style electromechanical ringers. This seems to be related to inductive spikes rather than power consumption. The late-model KX-TA624-5 does not have this problem.
Known to work, tested:
- LPT-300 - Pulse to Tone converter - http://www.dialerbuddy.com/lpt300.htm Approx $50
- Thoughts on this: This is a simple unit. Do not put this in line where the upstream carrier supports both pulse and dtmf, as that will register double-digits dialed. It works flawlessly otherwise.

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