SX-50 Integration with AVT PhoneXpress voicemail

[slowryde]

I am researching putting an avt phonexpress on an existing Mitel SX-50 and just want to check my thinking. Also I know this is not a true "integration" but an interface so please no hair splitting on my language

Integration = Analog/ONS

I should be able to hook up 4 analog lines, program class of service on the mitel and avt, set mwi strings in both, and program the forwarding digit strings for both.

The thing I can't remember is does the SX-50 require an MFRD sheet like the SX-2000. In other words is the voicemail option in class of service automatically available with the system or is it necessary to have purchased it when the system was first purchased.

Not 100% certain but my memory says that the SX50 was fully configured with all options and ports available.
