Hi,
I'm trying to call out from a SIP extension to an outbound destination via a
PRI E1 (Digium B410P).
Please take a look at the PRI debug below.

in AEL dialplan, I run:
Dial(DAHDI/g2/XXXXXXXXXX);
in the *CLI I see the following:
-- Requested transfer capability: 0x00 - SPEECH
-- Called DAHDI/g2/XXXXXXXXXX
-- Span 4: Channel 0/1 got hangup, cause 18
-- Hungup 'DAHDI/i4/XXXXXXXXXX-7'

So the fact that there's a timeout (MDL-ERROR) makes me think that there's some
kind of signalling error.
What could it be?
I noticed that my system clock was way off so I sync'ed it via NTP and tried to
place a call out. It failed again but this time the log shows a "T303 timed
out":
