What about ASPACs and parameters in e.g the GH? How do you test the MOH? It works with certain traffic cases, not if you are trying between 2 extensions, check this in Alex.
The traffic cases for MOH:
Parked on inquiry, CAW, camp on busy, auto CAB
Parked by PABX operator.
Queue towards a group (ACD, GH)
There might be some other traffic cases also,but I don't allocate them now (memory problem).
