Standard X100P cards are normally used as FXO devices. FXS devices (devices which allow you to plug in a standard telephone set) are of course available but are more expensive than FXO cards. This hack enables you to use the X100P (and clone) cards as FXS devices, subject to certain limitations:
- You must supply an external power source (12 V DC)
- The present version of the hack does not support ringing
- Some users have reported problems when using DTMF (tone) dialing. Rotary (pulse) dialing works well.
This hack requires you to make both software and hardware changes. You must download and apply a software patch to the asterisk zaptel (wcfxo) driver. In the simplest case, the hardware changes require only wiring changes - no other additional hardware components are needed (aside from the wiring and connectors).
