We're using a CISCO C3825 Voice Gateway
The modems are connected to FXS ports (VIC_4FXS Module).
This particular modem is connected to the FXS port whose line is
connected (on the other side) through an FXO (VIC_2FXO) and then going
through an E1 (VWIC_2MFT_E1). Then the E1 is connected directly to the
POTS.

I have 3 modems on that kind of config.
I have another 2 modems on the same config except they don't go
through the E1 the go out of the FXO and directly to the POTS.

And i'll repeat the modem session long attached is the modem going
through the FXS -> FXO -> E1.

Hope this helps.
