This issue has been discussed in the HKEPC forum. Using a telephine line connects FXS and FXO of SPA3000, then you may have VoIP Gateway between to two different VoIP accounts.
Using the following logical thinking:
FXS port: Current/Voltage sourcing port
FXO port: Current/Voltage sinking port
Examples of FXS port or device
1) Fixed telephone line from telephone company
2) Extension line from PBX system
3) FXS port of SPA3000
Examples of FXO port or device
1) Ordinary telephone set
2) CO port (connecting fixed line from telephone company) of PBX system
3) FXO port of SPA3000
Leitany had reported the setup procedures for this issue in HKEPC. If you have time, pleaea take a look at the VoIP thread in HKEPC.
