asterisk users - Jun 2005 - No ringing tone on outgoing SIP trunk

Hi!

I have configured a SIP trunk with a dialing rule.
The trunk behaves normally for incoming calls but when in used for 
outgoing call a strange thing happens.
When I place a call I cannot hear the tone confirming that the remote 
phone is ringing. I simply hear the voice as soon as the party picks up.
When the remote phone start ringing Asterisk receives a SIP packet 
stating that the call is making progress and puts through the incoming 
RTP I suppose.
With an external anonymous ATA from the VOIP provider all works normally.
Here is the debug:
