I have different voices and personalities on the phone depending on the nature of the call. On some calls, where I want to be intimidating to get something done I use my normal, deep, hard voice. I have a "nice" voice that I use when speaking with a woman on the phone. My last girlfriend told me once that when I used that voice I sounded gay. I just had to laugh as I thought I was just using a "nice" voice.
You can never tell about a person by what you perceive on the phone.
I've had more than one woman tell me, when I was using my normal speaking voice, that I sounded "sexy". Geez, if they only knew how ugly I really was
