[Asterisk-Users] fxotune Problem

[roly at redcetus.com]

Hi,

Well, I have a big problem with Asterisk, my problem is that when I'm in a
conversation, using zap channels, in a moment the line has a interferce
that produce a sound in the conversation, this sound is a electratical
sound I think, I was reading about that and I found that the utility
fxotune can help me to change some settings about the audio and the
supression of interferences. My problem is that fxotuno does not work, I
execute this script like that:

#./fxotune -i 4

The output of this command is:

/dev/zap/1 absent: No such device or address
/dev/zap/2 absent: No such device or address
/dev/zap/3 absent: No such device or address
/dev/zap/4 absent: No such device or address

/dev/zap/22 absent: No such device or address
/dev/zap/23 absent: No such device or address
/dev/zap/24 absent: No such device or address
...

Reading the source code I found that this error is produced with system
call O_RDWR.

My system is running Asterisk at Home 2.5 with Astersk 1.2.4 and Zaptel 1.2.5
compiled, with a Digium Wildcard TDM2400P with 24 FXO Modules.

I don't understand why fxotune can found /dev/zap/ devices.

I hope that someone can help me.

Thanks for yor help,
