Getting her to call you is most easily done when she messages you first, as you are just moving seamlessly to the next step. It is important to not waste time on extra steps if you can avoid it.
Let's say she sends you a message. This could be an Instant Message or an email. And let's say you chat a bit. Before drawing things out too long, simply say:
"Here's my number xxx. xxx. xxxx. . . . feel free to call me now"
"You can call me now if you want xxx. xxx. xxxx"
Chances are good that she will pick up the phone and call you within a few minutes. For this reason alone it is good to be online in the evenings after work or on the weekends, making it easy to do this. I have found that women tend to message more during these time periods anyway.
On the other hand, telling her:
"Here's my number xxx. xxx. xxxx. . . feel free to call me later"
will result in a bigger risk of flaking since there is a break in continuity. This can be overcome by chatting longer on IM (which is a whole other discussion). But in the interest of making the best of a situation, and being as efficient as possible for her and you, the above is a good practice to keep in mind.
And once on the phone you talk for a few minutes and then set up a meeting, in the usual way.
