Hi,
I4B in -current as of Dec 6.
The console displays this:
---snip---
i4b-L1 timer3_expired: state = F5 Identifying Input
i4b-L1 isic_recover: HSCX B: ISTA = 0x0
i4b-L1 isic_recover: ISAC: ISTA = 0x0
i4b-L1 isic_recover: HSCX B: IMASK = 0xff
i4b-L1 isic_recover: HSCX A: IMASK = 0xf8

i4b-L3 next_l3state: FSM illegal state, state = ST_OW - Out Wait EST, event = EV_T303EXP - T303 timeout!

i4b-L1 isic_recover: HSCX A: IMASK = 0xf8
i4b-L1 isic_recover: ISAC: IMASK = 0x2a

and I4B hangs in the dialing out stage. I don't know what the cause for
this problem is, in the middle of a connection something broke (if you
read this, the problem is gone at least for the time needed to flush
this mail out).
But the system should recover from this error. I needed to send a HUP
signal to isdnd and shut the interface down to trigger a redial out
(which naturaly doesn't work, the problem still exists). After a second
(or more) HUP/down/up/dialout-trigger sequence the logfile has an
"ERR decr_free_channels: controller [0] already 0 free chans!", but it
tries to dial out.
Between the first try to dial out and a restart of isdnd I get
additional output on the console:
---snip---
i4b-L2 i4b_next_l2state: FSM illegal state, state = ST_EST_AW_TEI, event = EV_DLESTRQ!
i4b-L3 T303_timeout: SETUP not answered, cr = 104

With -d 0xdf9 I get this output:

and there it stays forever (at least it seams so, I aborted after an
hour).
Bye,
Alexander (now going to look after the cabling and perhaps powercycling
the PBX).
