Noise while passing channel using tde205p card

Asterisk Users No Comments

Hello,
I have an Asterisk box with a digium TDE205p card. The problem is that I
have several “Goto(s-${DIALSTATUS}” sentences and while the call is
trying to find a free channel to establish the call, I get a little
noise in each “Zap/… is proceeding passing it to Zap/…” line.

My configuration is:

Digium card: TE205P
Asterisk Version: 1.4.21.2

But nothing changed.

I am thinking of upgrading Asterisk and Zaptel versions, but did you
have any noise problem with TDE205P? or is there any option/command to
avoid passing any audio until the call finds a free zap channel and
starts to ring?

Thanks in advance.
Best regards
Imanol
