There are adapters for handsets on Amazon, but interfacing to a phone could be harder as you have to provide DC power and deal with duplex audio on a single pair. If you're only using it as a mic, a 9v battery, resistor and decoupling capacitor might work.
An easier way could be to join the conference audio through SIP.
- pokeymcsnatch 2y agoCoupling capacitor, not decoupling, right? You want the AC signal and want to block DC.
- da768 2y agoYes, I stand corrected.
- jasonjayr 2y agoDoesn't the handset RJ10 have two pairs? If you skip the base, and have a sufficient amplification circuit, couldn't you just use the weighted handset to a 3.5mm connector?
