For the life me i cannot turn off the outbound caller displayer number, i use voipcheap.co.uk for landline calls and mobile calls but i dont want my number to display to the person i am phoning as i have a different incoming number, i have tried entering hidden in trunk cid, the extension Outbound CID, and also tried overriding in the route option to no avail.
