WAN smoothing with DSL and LTE


Hello, if a customer’s VoIP is poorly performing on their primary DSL, would adding LTE and using WAN smoothing ever be recommended, or should that only be used for similar connections? Just not clear how that would work being that latency on the DSL is around 25ms where LTE is more like 120ms.


We run VoIP over LTE alone and use WAN smoothing sometimes on LTE+DSL. Works fine. LTE is typically 50-90ms for us so not a big deal.


Thanks I do it on 2 x LTE all the time and it’s fine I just wasn’t sure how it would work using DSL + LTE.
