Addpac AP200D (FXO) + Asterisk: can't call to the PSTN

[pedropolian]

I have an AP200D (Addpac) of 2 FXO, which I want to use to call outgoing and ingoing calls (Local Area Network [with Asterisk] <-> PSTN)

Now, I can make a call from PSTN to the client of asterisk: 80, but I can't make a call from an extension of Asterisk to the PSTN

These are the configuration files:

sip.conf:

[general] 
port=5060 
disallow=all 
;allow=g729 
allow=ulaw 
;allow=alaw 
; 
;[80] 
; ...
 
[82] 
; AP200D 
type=friend 
host=dynamic 
context=internal 
language=es 
secret=82 
username=82 
callerid=82 
dtmfmode=rfc2833 
qualify=yes 
nat=no 
insecure=very 
canreinvite=no

extensions.conf

; Calls to PSTN: 
exten => _XXXXXXX,1,Dial(SIP/82/${EXTEN}) 
exten => _XXXXXXX,2,Hangup 
 
; Calls from PSTN 
exten => 11,1,Goto(ivr,s,1) 
; Here goes an IVR ...

When I want to call to the PSTN, the handset sounds like there were NO extension for that number (2636483).

Name/username Host Dyn Nat ACL Port Status
82/82 192.168.3.15 D 5060 OK (43 ms)
-- Saved useragent "AddPac SIP Gateway" for peer 82

In Asterisk it shows me:

-- Executing [2636484@internal:1] Dial("SIP/80-081d71f8", "SIP/82/2636483") in new stack 
-- Called 82/2636484 
-- SIP/82-081dc1a8 is circuit-busy 
== Everyone is busy/congested at this time (1:0/1/0) 
-- Executing [2636484@internal:2] Hangup("SIP/80-081d71f8", "") in new stack 
== Spawn extension (internal, 2636484, 2) exited non-zero on 'SIP/80-081d71f8'

When I make a debug in the AP200D, it shows me this:

Received SIP PDU from < 192.168.3.49:5060 >

What I should do in order to solve this problem? I need advices!

Thanks in advanced.
