Don't you just hate it when something was working and when you come to
use it in anger it's broken 
Something in the, fairly, recent series of Asterisk updates has broken
DIGITAL call passthrough.
I've an ISDN PBX behind my Asterisk Box (PRI ISDN comes into port 1 of a
Digium Wildcard and the PBX it connected to port 2 via an ISDN crossover
cable).
This PBX used to be able to make and receive DIGITAL type ISDN calls
through the Asterisk box... but something in the latest generation of
updates has broken it and although the calls seem to work the old PBX
just won't route traffic. Voice calls still work fine.
I've proven it's something in Asterisk by connecting the old PBX
directly to our ISDN PRI line and it still works fine.
It looks like the Asterisk box is trying to make a DIGITAL type call:
CLI>
-- Accepting overlap call from 'xxxxxxxxxx' to '0xxxxxxxxxx' on channel 0/15, span 2
-- Starting simple switch on 'Zap/46-1'
-- Executing [0xxxxxxxxxx at alchemy:1] Set("Zap/46-1", "CALLERID(number)=xxxxxx") in new stack
-- Executing [0xxxxxxxxxx at alchemy:2] Set("Zap/46-1", "SipChan=Zap/46") in new stack
-- Executing [0xxxxxxxxxx at alchemy:3] Set("Zap/46-1", "SipNo=46") in new stack
-- Executing [0xxxxxxxxxx at alchemy:4] NoOp("Zap/46-1", "Sip is 46") in new stack
-- Executing [0xxxxxxxxxx at alchemy:5] GotoIf("Zap/46-1", "?grecord:gnorecord") in new stack
-- Goto (alchemy,0xxxxxxxxxx,1
-- Executing [0xxxxxxxxxx at alchemy:18] Dial("Zap/46-1", "Zap/g1/0xxxxxxxxxx|9999|TWK") in new stack
-- Requested transfer capability: 0x08 - DIGITAL
-- Called g1/0xxxxxxxxxx
-- Zap/1-1 is proceeding passing it to Zap/46-1
-- Zap/1-1 is ringing
-- Zap/1-1 answered Zap/46-1
-- Channel 0/15, span 2 got hangup request, cause 16
-- Hungup 'Zap/1-1'
CLI>
The debug available on the old PBX (Network Alchemy Argent Office) is
errr... limited (read non-existant).
Any suggestions on how I can even start debugging this? Again I'm sure
it's Asterisk 'interfering' and I know it used to work in earlier 1.4.X
versions.
TIA

I have an outstanding problem with this,I have found that if you set
overlapdial to no on the internal leg ie connected to the pabx it works,
but you will have to set the pabx to dial en-block ie send all digits at
once

Could you please be more specific? What versions have that problem?
Could you provide some more details about your setup?

Well I've had a fun few hours testing versions and eventually found out
what brings the problem to light.
I went back through versions of Asterisk et al until I got bored and
reinstated a complete backup from last August onto my Asterisk box....
Voila! it worked (for inbound calls anyway).
Working my way forward in time... I eventually discounted all the
Asterisk, Zaptel and Libpri versions and boiled it down to me having
DYNAMIC_FEATURES=automon#autorecord#testfeature1
in the [globals] section of extensions.conf.
If I change this to DYNAMIC_FEATURES=automon then incoming DIGITAL calls
work. If DYNAMIC_FEATURES has anything more than this then it doesn't.
As a workaround, I've now got:
exten => _X.,n,Set(DYNAMIC_FEATURES="")
exten => _X.,n,Dial(Zap/g2/${EXTEN})
in the forward-to-my-old-PBX bit of the dialplan.
This works with 1.4.17, Zaptel 1.4.7.1 and libpri 1.4.3 (the current
stuff).

WRT Outgoing calls... this might help (unsetting DYNAMIC_FEATURES for
outbound stuff didn't do anything) but my old PBX is resisting dialing
en-block so calls fail
Why-o-why setting DYNAMIC_FEATURES causes the PPP hookup from my old PBX
to fail I really can't imagine. Any developers care to comment? (I'm
happy to insert debug and send info)... or should I file a bug report?
