I have never been asked for this feature before, but on a CS1000S 4.5, can you do extension barring, example ext 4000 cannot call ext4001 but ext 4001 can call ext 4000?
Yes you can by using CLS=OCBA in Extension CLS. also set OCB1,OCB2,OCB3 in CDB, OCB!,OCB2,OCB3 will be use as NCOS for extension. To restrict ext being calling a particular number u have to dial OCB FFC code and then 1 or 2 or 3 (1 means OCB1 etc..)
