What is the UDP High Port range mentioned that we create the service for in the 600/1000/1200/1400 firewall? Which port numbers should we be using?
We are having one-way audio issues with a Cisco CUCM environment immediately after upgrading our 5600 series cluster from R77.30 to R80.20 a couple of days ago. We have an open support case with CheckPoint support on this matter so still working through the issue.
Our scenario is that we don't traverse the PSTN traffic through our primary 5600 cluster; all Phone traffic is internal with the exception we have 4 small remote offices that we extend our network to. The remote offices are 600 series models. The only devices on the remote side are 1-2 PCs and a couple of Cisco 7900 series phones at each location.
Because of the VPN, we see a lot of encrypt and decrypt messages in the smart logs. When issuing the fw ctl zdebug drop command, we aren't seeing 'like fwconn_key_init_links (INBOUND)' messages or similar.
Is it likely this fix would apply to my scenario where the Call routing and call control are housed behind the 5600 cluster?
