Proxy Registration . Configure the parameters as described below. If DNS is used, fully qualified domain names FQDN can be used in fields requesting IP addresses below. For the Enable Proxy field, select Use Proxy from the pull-down menu. In the Proxy IP Address field, enter the IP address of the Avaya SES. For the Enable Proxy Keep Alive field, select Using Options from the pull- down menu.
