Track Ip Address From Email?

So for about a week now some guy has been calling my wife and when she answers he does not talk, just breathes into the phone. ( obviously this started to scare her ) then she had a guy at her work answer when he called again, this time he just hung up no breathing into the phone.A few minutes latter she gets an email.[Title: Phone Etiquette "Rule # 1It is impolite to have someone else answer the phone for you."/]is email is from gmail and it seems gmail does not include the ip address in the header. I've also tried the reverse look up for the phone numbers ( it's been 2-3 diff numbers all (210) 353-XXXXIs there a way to get the ip address from a gmail account or find name/address of the phone number ( they are land lines not cell )
