how to do better at phone sex

I’m (m) looking for pointers to pleasure my partner (f) better during phone sex.
We’ve tried doing it twice so far but things ends up abruptly because of irl situations.
The first time she ask me to utilise my tongue better and make more lewd sounds with it, 2nd time around afaik she seems to be enjoying herself better..
But afterwards when I ask her what should I do to make her enjoy herself more she keep on being dodgy about it..
Basically for future reference what are the dos and don’ts for phone sex, been googling at it but most advice that j found is for female..

I’m having fun, I want her to have fun as well..
She’s the one who initiated on this though, she’s more experienced in this than I do.
Sorry if it’s incomprehensible..
Cheers,
