Direct Outward Dialing (DOD) 
 
The UCM6200 provides Direct Outward Dialing (DOD) which is a service of a local phone company (or local 
exchange carrier) that allows subscribers within a company's PBX system to connect to outside lines directly. 
 
Example of how DOD is used: 
 
Company ABC has a SIP trunk. This SIP trunk has 4 DIDs associated to it. The main number of the office is 
routed to an auto attendant. The other three numbers are direct lines to specific users of the company.    At the 
moment when a user makes an outbound call their caller ID shows up as the main office number.    This poses 
a  problem  as  the  CEO  would  like  their  calls  to  come  from  their  direct  line.  This  can  be  accomplished  by 
configuring DOD for the CEO’s extension. 
 
Steps on how to configure DOD on the UCM6200: 
 
1.  To setup DOD go to UCM6200 web GUI->PBX->Basic/Call Routes->VoIP Trunks page. 
2.  Click    to access the DOD options for the selected SIP Trunk.   
3.  Click "Create a new DOD" to begin your DOD setup
