asterisk users - Oct 2005 - Problems Calling PSTN PSTN FROM ASTERISK

Hi
I terminated a call through SIP to a landphone i have the following 
problems.

1.) asterisk gives a fake riming tone, it does not give the real tone from 
the phone company.

2.) when I put the call on hold the on hold music is not very clear.
but when I talk the call quality is very clear.

if any of you guys have come across this please let me know what I did 
wrong.

regards
Kanishka

You probably should do a little bit of research via google and the wiki.

To get rid of the "fake ring tone", do not use the "r"
option in your
Dial statement.

For the music on hold problem, look around in your phone config (not
asterisk) for an option to disable "silence suppression". Asterisk
wants
a continuous flow of rtp traffic and the suppress silence does not
provide that. That's why things sound clear when you are talking.
