I'm trying to call from my PBX connected to FastEthernet0/0 to normal ISDN
PSTN phone numbers. Call's can't get trough. In debug i can see the numbers
is being dialed but no calls are made and after some time i get "All
channels
busy" "sh isdn hi" shows no activity at all.

the VIC2-2BRI should be my gateway to the PSTN. The PBX is on the LAN.

Um, that's your problem. It's not connected to a working ISDN circuit.
Unless I've misunderstood what you're doing...

Layer 1 and two should not be deactivated like that. Your router can't
see the ISDN switch (at the local exchange) etc.

If I call to a number connected to the router layer1 is active, so the ISDN
is ok.
But outgoing calls sort of "hang"

So, your BRI interface on the router is connected directly into the ISDN
offering from your telco - or do I misunderstand the topology?

I have assumed that you are using the router to interface between the
PBX over a lan (running VoIP between PBX and router) - and that a call
placed to the outside world from an extension on the PBX is routed over
the network to the router, which then picks up one of the BRI channels,
and pushes it out to the local Telco?

Yes, correct.

Dialing in is fine, except that cisco sends Mime SIP messages wich my PBX
doesn't understand.

Expires: 180
Allow-Events: telephone-event

I'm not sure I can be of any help then, unfortunately. All my
experience to date has told me that if layer 1 and 2 are deactive, the
isdn BRI port cannot see the ISDN Switch at the exchange, and it just
won't work. This may be a regional difference though, as I am in the UK
and I know ISDN here is different to the US, for example.

Best of luck, I'd be interested to know what it turns out to be!

Actually I've noticed something that looked really strange to me
yesterday. I've plugged 2 routers with BRI in the sam NT. Both of them
were "DEACTIVATED" but I was able to connect from one router to other
(using just one B chan - of course) or from both routers to some other
routers. Sometimes "DEACTIVATED" really means deactivated, and sometimes
not.... if someone can explain that it would be nice.
