Hey, RTP protocol over unicast or multicast IP?

Do you have any further logs? Did you enable the keep-alive feature in the advanced settings tab of Site to site connection?Thanks!

Only a few of the dongles seem to be supported. Not sure if CISCO has any plans to expand the support for other vendors/model versions. Check below link for current models supported:https://www.cisco.com/c/dam/en/us/td/docs/routers/csbr/RV340W/USB_Co...
