Tunnel mode - inbound calls
What this test checks?
This test checks that calls using the
special Tunnel mode protocol can be
received by receiving a test call from
the server.
What this result means?
Your port 6667 is closed and it needs
to be open.
How to fix this issue?
Since most of the router does not have
port 6667 open
Super Tunnel Mode (STM) has been
specially developed to fix this
problem. If you have super Tunnel mode
2 (STM2) working, you will be ok to
receive call without opening this
port. However, the audio quality may
not be optimized.
Direct connection to the Internet
Please open the 6667 TCP port at your
personal firewall. If you are running
Windows XP please

Internet connection via a router or
proxy server
Please open the 6667 TCP port at your
router or proxy server. For more help

help pages. If the proxy server is
a PC running ICS under Windows XP
