Hi to all
We have a strange noise in our phones when people answer our calls.
It’s a metalic noise, like “clack”.
the same happens When other side phones hangs.
We have two cards in our machine. One Digium TDM400D with one module.
We proceed to change the Digium card for other one and we have the same result. Problem persists.
If I connect a analog phone to the line conected to the FXO port of the TDM400P Card all is correct. No “clack”.
We change the telephone cable to discard anormalies and the clack persist.
We are using asterisk 1.4.9 and zaptel-1.4.4
We are running Debian Etch 4.0 with compiles kernel 2.6.18
Our configuration for the digium card is
rxwink=300 ; Atlas seems to use long (250ms) winks
channel => 1
How could I fix this sound? We just installed many TDM400P cards without this “clack”
Somebody have any idea something about this strange noise (It’s like a clack)
Any clue will be welcomed.
Thanks in advance.
