I have a Cisco SPA504G phone fully provisioned by 3CX (V9 SP4) - I cannot get the DND key to tell the 3CX system that the phone is on DND so other user can see the status. When this key pressed the status of the extention in the Assistant does not change. The status does change when I manually dial *61 - but I am trying to make these phones user friendy. PS. Under Regional I have set the DND Act and Deact Code to be *61 and *60. PPS. Software Version 7.4.6 & Hardware Version 1.0.0 Sure this might be a simple thing - thank you in advance.
