We were using 3 digit internal exts accepting 3 digits from the carrier. We just received 100 new DID and it looks like we will have conflicts ofthe last 3 digits of some of the DID already exist as exts, I.E 718-XX-1269. New 718-xx-3269. Should, can we change the system over to 4 digit internal exts while still expecting 3 digits from the carrier ?
