Howto add old caller to agent?

hi.
let’s ask my question by example :
i have call center for support in our company. there is some customer which calls to get support 2 times in one day to get support. when customer calls for the second time, is it possible to redirect customer’s call to the agent which answered for the first time to him???

thanks.
