I have a TL-ER6120 that is configured using Load Balance and FailOver. It will randomly drop VoIP Calls. Any suggestions about configuration for router or VoIP settings?

I guess you need to send all VoIP traffic out to only one WAN interface - (policy rules?) - otherwise the other phone server will see data packets coming from more than one IP for one call and reject one of them.
