Best practices for using UAD with VPN

[TommyMac4]

Experiencing issues with UAD and home users. I'm thinking that because of heavy bandwidth needed for voice and limited bandwidth at homes, it's giving us problems. Anyone know of any best practices for using at home? Options for UAD? Best not to use softphone or SIP phone? Should we use a separate home phone or cell phone? Any ideas would be helpful.
Thanks

Make sure home users are connected to an hard wired Ethernet port on their router as apposed to a wireless connection.
Landline Voice connection will lessen issues with latency as well.
