[Asterisk-Users] DTMF Caller ID w/o polarity inversion

[Eric Bart]

In France we just have a very short ring before the CID spill.
The CID spill is encoded in V23 instead of Bell 202

If you want the X100P to decode CID try this in fskmodem.c :
#define FLIST {1400,1800,1300,2100}

and maybe (i don't remember !) callerid.c :
#define CALLERID_SPACE 2100.0  // CCITT V23
#define CALLERID_MARK 1300.0 

If you want the TDM400 to send the cid see :
