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.

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
