Using SD-WAN to direct VOIP traffic to secondary line if ping rates pass threshold

[PaulTownsend]

Can the MX be configure to pass VOIP traffic on the secondary line if the latency on the primary gets too high?

Have a Client with multiply site and dual connections at each, leased of fibre as main and dsl as secondary.  Their have been a few occasions recently where the main line has seen high ping rates but hasn't failed.  For the VOIP phones this is a problem. So can the MX redirect the traffic if Pings pass a set limit example 50ms?

VOIP system is cloud based

Would it make more sense to just leave the VOIP system running on the secondary line? That way things are seperate. This can be done in "SD-WAN & traffic shaping" called flow preferences. You can choose what subnet can go out of WAN1 or WAN2.

@PaulTownsend this is something that it is easy to do over Meraki's auto VPN between sites, but I don't think you can do it to cloud servers.  The route I would look into is Meraki Insight as part of the SD-WAN plus license as that could monitor the paths and possible switch them over.
