Starting in MCD version 6.0 you can modify incoming DID numbers so you don't have to use system speed dials any longer.
But, there is also a feature in there that allows you to manipulate the incoming caller ID. Why? I'm still clueless but somebody must have needed it.
Now, I suggest they modify their incoming DID modifications rules to look at the incoming caller ID and if it finds a match simply allow us to change the destination number. Then when a block call hits the switch we simply change the destination number to something invalid.
Bada Bing, Bad Boom! - the caller is blocked.
That would be better than how I did it.
Maybe we should all get together and flood Mitel with DCR request.
