Hi!!
You sure can, you can use either application dial rules or a translation pattern to achieve this.
Application Dial Rules
In Cisco Unified Communications Manager Administration, use the Call Routing > Dial Rules > Application Dial Rules menu path to configure application dial rules.
The administrator uses dial rules configuration to add and sort the priority of dialing rules. Dial rules for applications such as Cisco Unified Communications Manager Assistant automatically strip numbers from or add numbers to telephone numbers that a user dials. For example, the dial rules automatically add the digit 9 in front of a 7-digit telephone number to provide access to an outside line.
For example, in Cisco Unified Communications Manager Assistant, the assistant can perform a directory search from the assistant console. The assistant can drag and drop the directory entry to the My Calls panel on the assistant console, which invokes a call to the number that is listed in the entry. The dial rules apply to the number that is listed in the entry before the call gets made.
Translation Patterns
In Cisco Unified Communications Manager Administration, use the Call Routing > Translation Pattern menu path to configure translation patterns.
Cisco Unified Communications Manager uses translation patterns to manipulate dialed digits before it routes a call to a destination. In some cases, the system does not use the dialed number. In other cases, the public switched telephone network (PSTN) does not recognize the dialed number.
