[Asterisk-Dev] Ringing Frequency not suitable for NL

When using the Digium TDM40B boards we experience a rather annoying problem.

The ringing frequency and voltage are fully compatible with the national
standard. 

(I know that this would also apply for NL, BE, FR & DE)

 

I changed the following lines and now it works fine;

 

wcfxs.c (Zaptel sourcecode)

 

{20,"RING_OSC",0x7EF0}   change to  {20,"RING_OSC",0x7E6C},
{21,"RING_X",0x0160},  change to {21,"RING_X",0x023A}

 

fskmodem.c (Asterisk sourcecode)

 

#define FLIST {1400,1800, 1200, 2200, 1300,2100} change to #define FLIST
{1400,1800,1300,2100}

 

 

Now off course it's great that this solves the problem, but shouldn't it be
implemented within the indications.conf or at least be configurable in a
normal way ?
