Hallo,
I know VoIP has been around for a long time and is no longer a real innovation. But here in Germany we're lagging a bit when it comes to digitization (that's VoIP in the end, isn't it?).
I'm just trying to dig into the topic a bit, because I promised my brother-in-law to look for him, because he wants to switch to it in his company. I just haven't fully understood how to go about it ...
Maybe someone can help me?
