Mi sono trovato a dover configurare un patton 4552 per gestire una linea ISDN Telecom e un pbx Asterik basato su FreePbx (2.10.1).

Visto che ho perso molto tempo a trovare una configurazione funzionante che fosse il più standard e semplice possibile e che dirotti il traffico in ingresso direttamente al pbx e viceversa, adesso la metto in condivisione.

PARAMETRI:

router internet: 192.168.0.1

patton: WAN -> 192.168.0.253

patton: LAN -> 192.168.1.1

pbx: 192.168.0.254

Si rende noto che è stato creato un utente 1004 con password 1234, che dobbiamo usare per il trunk sip con il pbx.

Di seguito la configurazione del pbx

Creiamo un nuovo trunk sip e mettiamo come trunk name : patton_trunk e nella sezione peer il seguente codice

type=friend
username=1000
fromuser=1000
secret=1234
context=from-pstn
qualify=yes
insecure=very
host=192.168.0.253
disallow=all
allow=ulaw&alaw

importante e la sezione from-pstn che deve essere uguale a quella del patton.

Adesso decidete voi inbound e outbound route!

Good Hack
