Problem with Choppy Audio in Cisco Unity Connection 8.x
Use the troubleshooting information in this section if the audio you hear from Cisco Unity Connection is choppy. Consider the following possible causes:
•The hard disk from which Connection is playing a recording is full. To resolve the situation, eliminate unnecessary files from the hard disk.
•The network connection to the Connection server is not adequate. To resolve the situation, improve the network connection.
•The Connection platform has a malfunctioning component. To resolve the situation, identify the malfunctioning hardware component, then repair or replace it.
•Another process is using too much CPU time. To resolve the situation, stop the process and run it when phone traffic is lighter.
Is this a virtual installation?
Does the choppy audio happen all the time?
Yes it is install on virtual installation.It happen all the time aslo we have IVR setup when you call the IVR number it gives you Choppy audio
1) What is the virtualization platform/version?
2) Have you installed VMware tools and confirmed it is up-to-date?
3) How many CPU cores does your hardware have, and how many VMs are configured on the server? How many vCPUs per server?
Below are the details

Virtual Hardware Configured
Virtual Support Supported
Processor Speed 2670
CPU Type Intel(R) Xeon(R) CPU E5640 @ 2.67GHz
Memory 6144 Mbytes

That doesn't really answer any of those three questions fully, does it?
OK - so you are running VMware workstation, and you are probbaly running it on your PC/laptop or some other non-server hardware?
Most likely it's a performance issue; your PC is stuggling to run the VMs and your base OS and whatever else is running all at once.
OK - so by 'VM Version 7' you mean 'I'm running VMware ESXi 5.0'? Or something else?
I would check the following:
- Have you configure the advanced parameters for disabling LRO?
- Can you post up grabs of your VMware network config, VM summary screen for each VM, and for the host?
