After doing so many meetings by VC for a while, I just had a phone call. I had forgotten how relaxing it is to not care about how you look while talking to someone.

Also, it's nice to have near-zero audio lag again. You tend to forget how obnoxious the lag is until it's gone.

On the other hand, my cell phone has way worse audio quality than VoIP; that gets tiresome after a while. (My obsolete landline at home with DECT 6.0 handsets has lovely audio quality, so it's a cell phone problem, not a PSTN problem.)
