SIP VoIP Configuration
If you know the IP address of the other VoIP device, and you are not behind a firewall, and you can ping the other device, you can likely make SIP VoIP calls directly between most VoIP devices. No server registration is required.

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.
Configuration Steps
Always enter your call sign in lower case.
These configuration is based on this Client Node Configuration Any other client configuration and/or any firewall might compromise the functionality.
