Got a call from this number, same Asian/Indian accented woman. It was weird though, because the conversation sounded like a real person was talking, but at the same time the woman sounded almost robotic. Said she was with South West Airlines, inviting me to a VIP event in Richardson, TX. Told me multiple times that it was not a sales call. I ended up hanging up in the middle of one of her sentences. My phone is registered on the do not call list, so if they call again I'll make sure they're aware of that.
