• Set the number 'Maximum Registered Users' for this domain
• Set the Expires value used by SBC when the remote device doesn't supply one (Default Contact Expire)
• Select Routing Method the system will use to route calls to registered users (if enabled in routing scripts).

  • Contact: Sends SIP Invite to the 'contact' from the Register message.
• Set the 'Default Contact Expiration' value when not supplied by the user agent.

    • Contact Remapping: Changes the user and the IP address.
