Contact tech support for your PMS vendor but don't waste time with the first person who answers. Ask immediately for an Interface Specialist... those are the guys who will know what the letters "SMDR" mean. The SMDR comes down as a string of ASCII characters and, like everybody else said, you can't change that from the Mitel end. The PMS has to accept that string and be programmed to parse the characters to extract the room number from the correct locations. Also be careful if your numbering plan puts a leading digit on the room number (i.e. Room 224 is Extension 7224) because the PMS needs to ignore or delete the leading digit to match the room numbers.

Good luck
