If the ported DID number is already in your number range of the IPS, then you simply create the extension to match the DID number. If the DID number is not in the same number range, it must first be programmed as extension level in CMD 200>1234>804, then allow number conversion to the PRI route 3518>rt>0, set the number of incoming digits (defaults to 4), CMD 3512>rt>3 = 4 digits, 2 = 3 digits. Then set CMD 7600>incoming number>to a table number,0000. CMD 7601>table number 0000>destination extension. Do the same for CMD 7602 (night mode).
