How to do it? Go to the university homepage `www.uos.ac.kr` - go to main service - click on `⑦ civil free call` - then click the `☎` button of the department you want. However, this service only allows in-bound calls, and can be used from outside the UOS.
Thanks to the Web-Call service, when we need to make a request of the school, we can do so more conveniently.
