7-24 block pattern works for 7 * 24

CME_Voice(config-telephony)#
after-hours block pattern 3 91900....... 7-24
You might have noticed based on the context-sensitive help output in Example 7-12 that
the CME router allows you to configure up to 32 indexes of block patterns. The initial
block pattern 1 matches and blocks long distance numbers; block pattern 2 matches and
blocks international numbers; block pattern 3 matches and blocks 1-900 toll calls. Notice
that block pattern 3 is followed by the 7-24 keyword. This additional syntax tells the
CME router to block calls to this pattern at all times. If you enter block patterns with this
keyword, phones exempted from other after-hours blocked numbers are not exempt from
these patterns.
Note:
If you need more flexibility than after-hours blocking provides, you can also use
Class of Restriction (COR) features with CME.
Cisco Voice over IP (CVOICE)
Authorized Self-Study Guide,
Third Edition, by Kevin Wallace (Cisco Press, 2008), has
more information on the configuration of COR on Cisco routers.

The final step in the configuration of after-hours blocking is to allow any necessary ex-
emptions to the policy, as shown in Example 7-13. You can add exemptions on a per-IP
phone basis or by using one or more PIN numbers to allow on-demand access to block
patterns (with the exception of the patterns defined with the 7-24 keyword) from any IP
phone. Example 7-13 configures ephone 1 to be exempt from the after-hours call-blocking
policy. Ephones 2 and 3 are configured with PIN numbers. In order to become exempt
from the after-hours call blocking policy, the user using the phone must enter the neces-
sary PIN number.
