[asterisk-users] Ring Freq

[Giampaolo TUCCI]

I'm sorry but doesn't work !
I have used:
-> options wctdm opermode=TBR21 fxshonormode=1 -> nothing
-> I have modified in usr/src/zaptel/ in all the files the next
occurrence 
{20,"RING_OSC",0x7EF0} -> {20,"RING_OSC",0x7E6C}
{21,"RING_X",0x0160} -> {21,"RING_X",0x023A}
I have recompiled, reinstalled and.. nothing !
Thje ring is the same
Where is the error ?
I use asterisk 1.4.21.2 and zaptel 1.4.12.1
Tnx
