Buenos días estoy realizando la configuración de una central con Isssabel y una línea sip provista por Netelip, pero al momento de realizar llamadas externas a mi número asignado obtengo tono ocupado, revisando los log y haciendo un sip debug y tcpdump al puerto 5060 obtengo lo siguiente:

Tengo activado el fail2ban, el firewall con las reglas básicas de Issabel
Mi configuración de la troncal es la siguiente:
Username=mi_usuario
Type=friend
Secret=mi_contraseña
qualify=yes
Insecure=very
Host =sip.netelip.com
Fromuser=mi_usuario
Fromdomain=sip.netelip.com
Disallow=all
Context=from-pstn
Canreinvite =no
Allow=alaw
Cualquier ayuda será apreciada.
Saludos.
