asterisk users - Oct 2004 - ISDN4Linux early call progress tones & announcements from the PSTN

Hello,

I would like to ask if anyone has solved the problem with 
Asterisk+ISDN4Linux cards, where there are no call progress tones or 
announcements from the PSTN when we dial ouot through the i4l card.

For the moment, if we don't inject the r option in the Dial command, 
there is only silence during the call negotiation...

Using Asterisk RC2 with Eicon passive PCI 2.01 card...

Thanks for any help,
