No idea. You have to write down your problems a little bit more precise!
What means all sounds? The dial-tone at the caller or the ringing tone
at the callee?
I'm also not sure if the problem is your asterisk or ser configuration
as I don't know your configuration.
Which UAs do you use? Softphone? Hardphones?
regards,
Klaus
