PolyCom Group Units getting Unknown calls from ID 100

While we are on video conference calls a call comes into our Group 700 unit from unknown ID 100 and we can not cancel the call or answer it.  What is this and how do we stop it?

 

Thanks

Hi stuart100

 

Please, don't afraid to use the community's searching tool :-)

 

Your issue has been already discussed  >here< , >here< and >here<

 

Note: recently I've seen SIP and H323 the same calls, earlier I met only SIP calls.

congratulations - you are likely getting a sip / hack attack  aka: sipvicious attack

if you have a fire wall you can block the ip address it is comming from to start

if you have an sbc - you can kill the incomming invites fron 100

a packet trace on port 5060 will show you more information
