Hello! I just want to ask how to change outgoing CID? instead of showing my own number I want to replaced it with our company main number so that anyone receiving a call from me will see our company main number… We are using UCM-6510. Thank you!
Connection type - PRI, SIP, analog?
Connection type is SIP
Well, it depends on a number of factors - Will your provider allow you to change or, are they controlling it and if they allow the change, in what field are they looking.
Most have success using the DOD settings associated to a trunk. You can find the details of how to setup in the admin manual for the UCM.
Eliminate the settings you currently have and then try DOD and see if this works for you.
