Preface

This will help you configure your device so it correctly register with our servers. This will allow you to dial by call sign and/or assigned phone numbers. Having your device registered in a server also makes it easier when you are behind a firewall.

Pre-Configuration

To register your call sign, send an email to netops@nmhamwan.net

After your call sign is provisioned we will send you an email with registration information and the "secret" to be used with your call sign to register your device in the servers.
