[asterisk-users] Problem with SIP trunk I've set up between two * boxes.

Hi!  I'm trying to set up a SIP trunk so that I can test calls, etc., 
between a new Asterisk box, and an old 1.4 box.

---------------------------------------------------------------------------

New box:
root at asterisk1:/etc/asterisk# head -1 sip.conf
#include siptrunk.conf

siptrunk.conf:
[box1] ; All box1 extensions; see extensions.conf
type=peer
context=adhearsion
host=172.17.0.17  ; IP for old system
disallow=all
allow=g729
canreinvite=yes
qualify=no


Old box:
root at asterisk1:/etc/asterisk# head -1 sip.conf
#include siptrunk.conf

siptrunk.conf:
[box2] ; All box2 extensions; see extensions.conf
type=peer
context=local_SIP
host=172.17.145.145 ; IP for new system
disallow=all
allow=g729
canreinvite=yes
qualify=no

extensions.conf snippet:
[local_SIP]
include => aggregate
include => passthrough
exten => _7XXX,1,Dial(SIP/box2/${EXTEN})
exten => _7XXX,2,Hangup()

-----------------------------------------------------------------------
When I dial, all I get is (I'll attach the full dialog up to that point 
from SIP debug, below.)
     -- Executing [7444 at local_SIP:1] Dial("SIP/6110-08291cb0", 
"SIP/box2/7444") in new stack
     -- Couldn't call box2/7444

INVITE)
   == Everyone is busy/congested at this time (0:0/0/0)
-----------------------------------------------------------------------

Where am I goofing up?  Any pointers?

Thanks!

-Ken
