Click Add New.
With this dial rule, I am going to strip out just the + and then add a 9 to the beginning
(see Figure 9.26). This will change the number +13125551212 to 9 13125551212, which
CallManager can then have my IP phone dial. If I don??™t add the 9 prefi x, my IP phone will
try to dial just 13125551212 and will fail because I need a 9 to dial an outside number.
Figure 9.26 Dial Rule Confi guration
Notice that I have 12 as the number of digits: CallManager considers the leading + to
be a digit. Click Save.
Create another rule that will handle incoming calls bound for users??™ extensions. This
time, we will strip off everything except the last four digits (see Figure 9.27). And because
these are internal calls, there will be no need to add a 9 prefi x.
310 Chapter 9 ??? Integration with PBX and IP-PBX Systems
Click Save. We have completed the CallManager confi guration needed for the Remote
Call Control integration.
As I mentioned before, I am assuming that you have already installed CUPS into your
environment. More CallManager confi guration is required to get CUPS installed and integrated
to CallManager (such as creating an application user), but I am going to leave that for you to
do on your own or with a Cisco partner. I have covered all of the necessary changes to a basic
CUPS install for an OCS integration.
Confi guring CUPS for an OCS Integration
Along similar lines, I will not go into detail regarding how to confi gure CUPS to integrate
with CallManager; again, check Cisco??™s documentation for this.
