I'm using a cheap Digium TDE-410P clone (electrically-identical hardware, runs same drivers) with two FXO (exchange line) and two FXS (telephone) modules. The latter accept pulse dialling (even during a call, e.g. to respond to voice prompts) and can ring a 1kΩ bell, so I can recommend this card as a good solution for vintage phone colections.

I wouldn't use a cheap clone card in a mission-critical application, but they are certainly fine for experimenting with.
