6. Don't call her frequently on Mobile or don't force her to meet:

Even if, you liked her so much but don't show your emotion calling her again and again. If you do that will convert her attraction into repulsion & one day, she will not pick up your telephone because your call starts to irritate her

Accordingly, don't force her to meet on telephone. Whenever, you desire, have to say in different way so that your emotion should not seems visible that especially, you want to meet her. in view of this, you have to make her realise that your desire is not for her, it is for something else. Then, she herself will feel avoided but that behaviour is sign of sexual tension. She will try to come to you but you will not make her more attention. Just ignore.

in view of above, you have to wait her call or you make her call probably once a week not daily that gives a message that you don't care her.
