Tinashi 's comment is almost right except the first line—— calling by phone and calling a waiter using different verbs in Chinese 打电话means calling by phone , and 打is the verb means "calling"(also means beat one up),and 电话 means "phone" however, calling a waiter in Chinese is 叫服务员，it's more kinda like ask waiters for help in Chinese.
