Flirting with a butch over the phone?

ok so Ive dated before but not like this lol I met this very nice lady at a bar that was out of town here recently. (about 2 hours from where I live) We have only met once but we had an attraction there, shes an over the road truck driver so there is no real way to have face to face conversations to get to know each other, what are some tips for someone that has done this before? we have text and talked, its just hard do "flirt" much when you don't know them or cant see their facial expressions. Just need suggestions to get to know her better, I do think we will eventually meet back up but just looking for something to make sure lol we will have another meeting and I don't mess up lol
