Is there a VOIP client compatible with aarch64?

Maybe not the solution you are looking for. But you can use teams-for-linux, which basically is an electron wrapper around the MS Teams Website and is especially compiled for aarch64.

And you can create shortcuts in Chromium, so you can use several Web versions of the applications each in a separate window. Tried this with Discord, which is working suprisingly well so far
