Just as a side note. I have always raised with PF the limitations of make busy reason codes This is due to the fact that even if you have 6 3300 or MCD connecting to the CCM you can still only ever have 11 make busy codes. Why can't each 3300 have their own assigned make busy data allocation within the CCM, as the helpdesk make busy codes will be different to that of the HR make busy codes and so on.
Never, got a proper reply.
