"No".
When FXO port answers the call, FXS may send a Polarity Reversal. If this
interval is shorter than the value of "Polarity on Answer Delay", the Polarity
Reversal will be ignored. Otherwise, the FXO will onhook to disconnect the
call. The default setting is 600ms.

voltage drop in the line. The default setting is 200. The valid range is 50 to

Configure the ring timeout (in ms). Trunk (FXO) devices must have a

8000.
