Problems with incoming calls on videoconference systems, from Botnet

We are having an incresingg problem with incoming calls on all our videoconferencing systems, they are all on public IP adresses, and in the start it was only SIP calls, now we are also having H323 calls.
I would like to hehar some experience in solutions you have, I have been looking at some different hardware boxes that claim to solve that problems, but are they working?
We have a mixture of Polycom, Tandberg and Lifesize system

All the best



  • Hi Per, we configured a IDP roule on the FW in front of H323 endpoints blocking the "Cisco spam calls" that did the trick also Lifesize has release the software revision ‘LS_RM3_2.4.0‘. it blocks the spam calls.
