asterisk users - Jun 2005 - Anybody knows how to setup chan_misdn incoming calls

Hi.

 I want to handle incoming chan_misdn traffic by asterisk, but I've got
message - 'Extension can never match, so disconnecting'. What I'm
doing
wrong ? How I can pass incoming dialed number (dad) to misdn context (in
my case 'dss1_incoming') ? Works unrouted calls (s extension) if I set
immediate=yes in misdn.conf, but I want to route calls by dialed number.

log snippet :

.........
