12CHAPTER 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:

1Start the remoteCli process by entering these commands.

cd /opt/3com/VCX/callprocessor/remoteCli/bin

./remoteCli -call

2After remoteCli starts, enter this command.

>config CcCfg ChallengeAllCalls=true
