[asterisk-dev] TDM400 CPC signal

[Ale]

Hi all,

Regarding the problem mentioned on these mail[1][2]

i've contacted my carrier and to correctly hang up the analog line 
asterisk should open the circuit for at last 500-700ms the signal to 
send is a CPC (Calling Party Control), how can assure that asterisk 
correctly works.

I've take a loot at zt_hangup function on cha_zap.c then wctdm.c to 
arrive at zaptel.c and i didn't find what i looking for, may someone 
point me on the right direction?

And can asterisk send CPC signal with wctdm driver on a TDM400 over FXO?

Any hint is appreciate.
