This is for outgoing calls, which works fine. The problem I am facing  
(and Claudio too) is for the incoming calls from the PSTN provider.
Answering the call first or adding r / R options does not work either  
in this case.

I have opened a case with my provider and they told me that my gateway  
is not sending any ringback tone to the caller. I have the following  
logs in incoming calls from ss7 :

[2010-06-16 20:26:25.755] DEBUG[31943] l4isup.c: SS7 indicate CIC=1.
[2010-06-16 20:26:25.755] DEBUG[31943] l4isup.c: Sending ALERTING call  
progress for CIC=1 in-band ind=0.

But there is no media. So I guess it has something to do with asterisk  
ringtone generator.

Btw, to answer to your question, Claudio, I haven't found the solution  
yet :-((
