thank you four your answer. I think you have misunderstood the problem. It’s about a ip address change of the sip trunk, not of my asterisk server.

Kind regards,

It checks the outside IP address by querying http://checkip.dyndns.org <http://checkip.dyndns.org/> and compares it to the IP address stored in the parameter “externip” in the [general] section of sip.conf. If the two values are the same, the script exits quietly. If they are different, the script updates “externip” with the new address, does a sip reload, and shoots me an email saying there was an update. It's a fairly simple and straightforward process and does the job. I use this script for all PBX’s that are behind a NAT. I hope this helps.
