Use "from" as a column name in sqlalchemy+marshmallow

Question

I have a table representing a phone call and want to store that data

from app.db import db
from app.schema import ma

#db = SQLAlchemy()
class phoneCall(db.Model):
    __tablename__ = "phoneCalls"

    callerid = db.Column(db.String, primary_key=True)
    #from = db.Column(db.String)
    _from = db.Column("from", db.String)
    to = db.Column(db.String)
    duration = db.Column(db.Integer)

#ma = flask_marshmallow.Marshmallow()
class CallSchema(ma.SQLAlchemyAutoSchema):
    class Meta:
        model = phoneCall

Since from is a SQL keyword I can't directly use that as a column name. I tried setting it as

    _from = db.Column("from", db.String)

But when I return a phoneCall.query.all() I get the column name as _from. Additionally, I'm using a dict with the key as from to populate data into the table as well. How do get around this restricted keyword to accept input and also display the output of the query as

Input

call={'callid'='call34346346346',"duration":10 "from": "+1234", "to":"+1234"}

Expected output

[
    {
    "callerid": "call34346346346",
    "duration":10
    "from": "+1234",
    "to":"+1234"
    }
]

Actual output

[
    {
    "_from": "+1234",
    "callerid": "call34346346346",
    "duration":10
    "to":"+1234"
    }
]
