QHow do I know that I?m having a NAT-traversal issue?

   ANAT-traversal problems manifest themselves in several easy-to-identify ways. If you are experiencing any of the following problems, you may have a NAT-traversal issue:

1. Are you having one-way audio?
2. Is the call setting up (ringing), but missing sound?
3. Are calls not setting up in the first place?

If you are experiencing any of these issues with your VoIP service, call FTS?s Customer Care Specialists at 1-800-649-2211.
