I’m sorry for the my trivial quest.
I Have asterisk 1.4 with TDM 400 with FXO and FXS, and works fine from
Now I want to connect a device to TDMFXS that want a ring frequecy of
25 hz to activate: i am italian, and usually the ring freq is 20 hz.
The other time (I have used that device several times with other
asterisk installation) I have modified /etc//modprobe.conf and added the
options wctdm opermode=TBR21 fxshonormode=1
But now this not works: I have changed the TDM but nothing……..
How is possible to modify ring frequency ?
