Forced entry of account code
To maximize system security, it is recommended that the Forced Entry of Account
Code feature be enabled and administered on the system.
NOTE:
For DEFINITY G2, Call Detail Recording (CDR) is required with this option.
See ‘‘Call detail recording/station message detail recording’’ on page 5-53
for more information. Depending on the required length, the account code
may replace other data in the CDR report.
An entry of an account number (1 to 15 digits) can be required for the originating
station COR/COS, toll calls, or WCR network calls. If an account number is not
entered when required, the call is denied. Although the account number is not
verified, callers must enter the appropriate number of digits set by the system
administrator. This adds another level of digit entry that a hacker must crack to
gain access to an outside line.
World class routing (Communication Manager,
MultiVantage Software, DEFINITY ECS and
DEFINITY G2.2 and G3)
The World Class Routing (WCR) feature replaces and enhances the AAR/ARS
feature. Specific digit strings are assigned to either allow or deny calls. The 900
look-alike numbers can be routed for interception. The 800 numbers for ICX
carriers can be blocked. This still allows normal 800 numbers to be dialed.
Specific international numbers can also be blocked.
You may also route 0 or 00 calls to a local attendant for handling. In addition,
101xxxx + calls can be restricted. Certain laws and regulations may prevent you
from blocking these calls, however. Check with your local or long distance carrier
for applicable laws and regulations.
If possible, use WCR to shut down toll routes during out-of-business hours by
using Time-of-Day routing.
