I am in a process of setting up the bulk voice messaging distribution for my client and have current limitation of 96 ports to access VM and have more than 400 phones installed.
When I initiate the mass voice messaging to all the phones and if when all the users try to access the VM, partially get busy signal or wait for longer time before they can get to VM.
Is there any way to send the messages in a particular interval (batch)
How do we avoid adding additional Unity server for VM to achieve this.
Thank You in advance.
