Asterisk cuelga automáticamente cuando intento llamar

Asterisk cuelga automáticamente cuando intento llamar

Acabo de configurar un servidor con Asterisk configurado pero cuando intento hacer una llamada VoIP la línea se corta automáticamente...

Utilizo CommPeak como proveedor SIP y Bria para la interfaz.

Aquí está mi sip.conf:

[general]
allowguest=no
context=default
bindport=5060
dtmfmode=rfc2833
disallow=all
allow=alaw
allow=ulaw
allow=gsm
allow=g723
allow=g726
allow=speex

; replace INBOUND_SIP_USERNAME and INBOUND_SIP_PASSWORD
; with your Inbound SIP Registration credentials
register => USERNAME:PASSWORD@trunk

[8763442]
type=friend
host=dynamic
context=from-internal
username=USERNAME
password=PASSWORD
qualify=yes
nat=force_rport,comedia

[trunk]
type=peer
host=eu1.sip.commpeak.com  ; Europe POP
;host=amn.st.ssl7.net ; North America POP
context=from-trunk
qualify=yes
defaultuser=USER
remotesecret=SECRET

Mi CommPeak tiene suficiente crédito para hacer llamadas
