Is load balancing possible with the device or not? I keep reading that it should be possible, but on the AVM site it just says fallback...? Thank you very much.
It can at least switch automatically to the other internet connection in the event of a failure (in my case from mobile to cable) or if the speed becomes very slow (but I could not simulate this). But it did not go completely unnoticed. The connection was gone for a while (minutes). The SIP phone could not switch cleanly either. But anyway, I wouldn't call it load balancing: it's simply a fallback.
