I need consultation about configuration VCS Starter Pack that will help against SIP scanners..
Looks what we have: VCS with public IP, 4 SX20 also with Publick IP in different cities(If it needed we could hide them behind NAT) and some codecs that already registered on VCS but new configuration should not touch it( is it possible makes apply different configuration between different endpoints?)
These 4 codecs constantly are under attacks of SIP scanners. So we should registrate them to VCS ( could we do it properly if we hide them behind NAT?).
Please help me with configuration of VCS Starter Pack that reduce this threat.
Thanks for advance
