asterisk users - Feb 2009 - Noisy Ring Back Tone with TE205P card

Hi,
I am having problems with an Asterisk with a Digium TE205P card. The 
issue is that the Ring Back Tone is noisy. I am making modem's calls and 
this noise influences on the initial negotiation protocol, so modems 
have to recall.

My configuration is:

Asterisk version: Asterisk 1.4.21.2
Linux version: CentOS release 5.2 (Final)
Card: Digium TE205P

[HANGUP]
exten => s,1,Hangup

[DID_span_2]

I have no idea about where could be the problem. I can't see anything 
rare in the logs....
Any ideas?

Thanks

Hi,
I stilll continue with the problem but I have noticed something new that 
maybe a clue. The noise during the call progress is made by the 
appearance of the different lines in the asterisk CLI, I mean, each line 
is posted in the CLI generates a noise in the call's signallling tone. 
For example, if I try doing a call during a resetinterval option, which 
reset all free channels, each line posted in the CLI generates a burst 
noise.
Any ideas?
Thanks
Regards
