Configuring SPA9000 NAT Traversal

The SPA9000 NAT Traversal page appears after you click the Next button on the
Configure SPA9000 ITSP Voice Service page.
Proceed according to the NAT traversal services provided by your ITSP:
•
In most environments, the ITSP deploys an SBC to deal with traversing
networks that deploy network address translation. If your ITSP uses an SBC,
leave all fields blank. Then click Next to display the Configure Outbound Call
Routes page.
•
If you need to configure for NAT traversal, see
