I received an email requesting I phone this number saying it is from an Audra Davenport
I do not to my recollection know her and wonder id f this is a scam

This is almost certainly a scam.  I received several of these to various spamtraps, with differing phone numbers including this one.  Each one asked the recipient to send a text in reply, which is most likely a way to get someone to give up their cell phone number for further scams.

received e-mail from this number, said the name was Marta Gibson, said she thought she dated me in high school, No idea of who this is, i am from a VERY small town, 65 people in my class 270 in entire high school, no one by that first name in my school at all. i am SURE this is a scam
