[Asterisk-Users] Problems Calling PSTN PSTN FROM ASTERISK

[Kanishka Somaratne]

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
