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:

PORT     STATE  SERVICE

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
