This is the script i’m using to overcome this problem. It check the
external IP and update the sip.conf with the new IP . Run this script as
cronjob every 5 minutes
#!/bin/bash
# checksetexternip.sh
# Author: John Cahill email at johncahill.net
# Licence: GPL v3
# Description: script that queries checkip.dyndns.com to find the server's
external IP address. Updates asterisk's externip value and does a sip
reload if necessary.
