Receiving calls the LAN IP. Help, please

Hello

First time poster, but I couldn't find a similar thread.

My C60 telepresence codec is receiving calls repeatedly every 30 seconds to a minute on my local network.  The call alert incoming says it comes from an IP address included in our premises: 10.10.10.XXX, and for each incoming call, the last 3 digits of the address IP is different (10.10.10.15, then 10.10.10.25, then 10.10.10.700, etc.).  If I leave it alone for a week, I'll be back to more than 1,000 missed calls and the machine is frozen.  Often it will be frozen every time I wake up, and I have to restart.  I have not changed the configuration at all since the latter was working fine.

I contacted my gateway ISDN service provider first disconnect and their services to solve the problems, but the calls were still coming.  I just unplugged the Cat6 cable to see if this is the case of in the codec itself.  The calls stopped coming in and the area is sensitive again.

Something in my local network called the box via the IP address.  Any of you have heard or seen what is happening before?  Any advice?

Thanks in advance,

-Rory

Hi Rory,

Certainly looks like a SIPVicious (or similar) probe.  These have been mentioned several times in the forums before.

One thing that you can try on your endpoint is to put "xConfiguration SIP ListenPort: Off '.

See Bug CSCue55239 - you can upgrade the firmware on your device too.

PS - You may also be interested by this safety notice if you do not have a contract of service - it will help you to spend at least at TC6.1 if you are on an older version of software on your C60.
