[h323plus] Possible Entry through h.323 at Port 1720

TCP 1720 is used for H.323 call signaling and is only used during a video
conferencing call.

The device maybe using port 1720 but it may not be video conferencing
related unless there is a video conferencing device behind the router
connect to a device outside the router and you certainly cannot configure
the router on that port.

Subject: [h323plus] Possible Entry through h.323 at Port 1720


Hello everybody,


I am new to this list and have just a simple question:


We are using an Sierre Wireless Raven XT router to send data from a remote
place to our servers

And at the moment the connection is not fully established (we cannot connect
with Loggernet Campbell Scientic Program).


A port scan from the machine gives:


1720/tcp open   H.323/Q.931


Which is the only open port (no SSH, no HTML Port).


Is there a possibility to get through this port to change the configuration
of the router?

Any help would be appreciated.


Best regards,

Christian Braun
