How can I change the Outgoing Caller ID Set in Cisco Unified Call Manager? (External Phone Number Mask)

I'm managing a Cisco VOIP system with CUCM version 6.1.2. I've inherited the system and only know my way around the phone level.

Our default Caller ID (or should I say External Phone Number Mask)  (i.e. when call an external number) is set for all phones to be our main number. First Q - where is this value set?

We'd like to set about 80 of our phones to a mask of 123-456-XXXX with XXXX being the extension number. Then we have about 20 phones that aren't direct dial numbers that we'd like to set to 123-456-6000 (our main number), or even better, 123-456-6000 xXXXX. All of our lines currently have the External Phone Number Mask set to 123-456-XXXX, but clearly there is a global setting that takes precedence.

thanks

Right now we get a lot of calls back to the main number - did you call me? Who called me? and our receptionist can't tell them. I realize that there are human fixes to this problem of course.

The calling party number transformations (which affect caller id) can be set in a few places.  I'd start by looking at the route patterns and translation patterns.  It could also be set on the lines themselves, but since you mentioned that it was system wide, it's unlikely you'll find it there.
 
If you have CCO access, you can find more information at these links:

The second link above is the stuff.
http://www.cisco.com/en/US/docs/voice_ip_comm/cucm/admin/6_1_1/ccmcfg/b03rtpat.html

Open CUCM
Call Routing->Route Hunt-> Route Pattern. We have about 15 different Patterns set up - International Calls, the various local area codes, etc.

You have to change the Calling Party Transform Mask for each pattern if you are going to make a global change, or check the Use Calling Party's External Phone Number Mask if you need to individualize the setting by line. (We do because we have some phones that don't have direct dial numbers associated with them. These phones should display the main number.)

Obviously if you check the Use Calling Party's External Phone Number Mask field in the Route Pattern Configuration, then go to each line and check the value in this field.

if you check the Use Calling Party's External Phone Number Mask field and the field is blank on the line level, the system appears to use the Calling Party Transform Mask by default.

I'm glad to have helped.  BTW...you could also use different partitions for the numbers that don't have direct dial numbers vs. the ones that do.  Then have two different sets of route patterns with different Calling Party Transform Masks.  That kind of setup would be good if you wanted to use different dialing rules or restrictions for the two types of numbers.  I would just use the method which provides the features you require and is the easiest to implement and maintain.

I'm managing a Cisco 3900 CUCM and only new to this system.

Currently all outbound Calls was set to display our main reception number 03 9783 5000. There is another section in the company want to have their own main number 03 9783 5111 for outbound so the customer can call (03 9783 5111 ) them back directly instead to call main reception number.

Could someone give me some example how to do this?
