[asterisk-users] Q; Recording when a bypass phone is used

[listuser at spamomania.co.uk]

The answer is probably no, but I have a bypass PSTN phone ahead of my
Asterisk 1.6 box.

I noticed when a call is answered on this bypass phone, the 'record'
option still partially operates on Asterisk, but stops after the ring
detection goes low.

Is it possible to have Asterisk record when a DAHDI channel is detected
in the off hook state, even if this is outside of Asterisk?
