[asterisk-users] Constant ''CHANUNAVAIL' on PRI for Outgoing Only

Hi,

I'm hoping that somebody could possibly assist me with this. I've tried
everything and I believe that my settings and configurations are 100% -

 CentOS 5.1 - 2.6.18-53.1.14.el5
Asterisk 1.4.19
libpri-1.4.3
zaptel-1.4.9
Connected via a Digium TE122P to a E1 PRI

Incoming on any one of the numbers assigned to the E1 work fine and arrive
at the Asterisk demo.
No outgoing calls work and the following error is given:

    -- Executing [0215512345 at outbound:1] Dial("SIP/4700-085de988",
"Zap/g0/0215512345|300|Ttr") in new stack
    -- Requested transfer capability: 0x00 - SPEECH
    -- Called g0/0215512345
    -- Channel 0/1, span 1 got hangup, cause 44
    -- Forcing restart of channel 0/1 on span 1 since channel reported in
use
    -- Hungup 'Zap/1-1'
  == Everyone is busy/congested at this time (1:0/0/1)
  == Auto fallthrough, channel 'SIP/4700-085de988' status is 'CHANUNAVAIL'
    -- B-channel 0/1 successfully restarted on span 1

Here are all my settings related to this including an attached output of a
"pri intense debug span 1" as span-debug.txt

I really hope that somebody is able to assist me as the Telco says nothing
is wrong on their side (even though they are sending somebody out to come
verify)

Thanks in advance!
