I have configured 7 SNOM 360 phones using the auto provisioning feature in 3CX v.5. Voice Mail extension on 3CX is 88 because it is configured with two digit extensions. Three out of 7 phones still dial 999 for VM and I cannot get them to dial 88. I have re-provisioned them with no success. Does anyone know how to manually configure this? I can change the programming of the button to dial 88 hard coded, but then I don't get the MWI light. Any ideas?
