Is there a way to convert incoming digits in a BCM? We have CS1000 that is connected to a BCM using SIP trunks. Their old CallPilot number 439. Now that number in a DID in the CS1000. We would like to convert that to unused number like 500 coming from the CS1000 and have 500 point to 439 in the BCM. If that isn't possible can we add the number 500 to be a pilot number in the BCM's CallPilot?
