Hello, This is an automated courtesy message from Exgn. We received CHANNEL IS UNAVAILABLE when our servers attempted to reach you. This is caused by either your server being offline or you are not registering with us correctly. You can register via SIP or IAX. Your telephone number is currently routing to your Asterisk PBX server. You can change how your number routes by logging into the control panel at https://secure.exgn.net/ and clicking on DIDs. There is a 'Routing' option under the action menu for each DID. Sincerely, Exgn LLC support@exgn.net
