12 CHAPTER 1: VCX SYSTEM SECURITY
IP Messaging Ports The IP Messaging System (vcxums) uses these ports. If your VCX system
does not use IP Messaging, the integrated firewall on each VCX server
will disable access to these ports.
Passwords VCX systems that are shipped from 3Com have default passwords
configured for system-level login IDs.
3Com strongly recommends that you change the passwords for these
login IDs:
■ app
■ cworks
■ root
■ vcx
■ oracle
■ tomcat
3Com recommends that you secure the new passwords in a manner
consistent with your company’s security guidelines.
SIP Invite Messages 3Com recommends that you configure the Call Processor to challenge all
SIP invite messages.
To configure this capability using a remoteCli command:
1 Start the remoteCli process by entering these commands.
cd /opt/3com/VCX/callprocessor/remoteCli/bin
./remoteCli -call
2 After remoteCli starts, enter this command.
>config CcCfg ChallengeAllCalls=true
