Problems with FSK CallerID A1200p + dahdi + Elastix 2.0.3

Hi Everyone
I'm having problems detecting the caller id with the a1200p it says unknown, my Colombian telco company told me that they are using FSK. I have tried everything with the signalling

I will appreciate any help.

This is my chan_dahdi.conf

[trunkgroups]

[channels]
;context=from-pstn
language=es
context=from-zaptel
signalling=fxs_ks
rxwink=300
; Atlas seems to use long (250ms) winks

;Uncomment these lines if you have problems with the disconection of your analog lines

#include dahdi-channels.conf
#include chan_dahdi_additional.conf

and this is my dahdi_channels.conf

Hi,
you have to check few things:
1） set this in chan_dahdi.conf:
cidstart=ring

2) load driver with your country code : modprobe opvxa1200 opermode=your country code

3) check the indication.conf, set it to your country.
[general]
country=your country code

4) check the /etc/dahdi/system.conf set it to your country.
loadzone = your country code
defaultzone = your country code

You can Analysis to determine the audio file
