The answer is Yes, you can. Microsoft Skype for Business supports calling on Landline and so does Microsoft Teams. This is possible if you have the needed Microsoft licenses, like Phone System with Teams. You will just have to tap on Calls located in the bottom bar and dial the number from the dial pad. If the App has got permission to access your contacts, you can also make calls to personal phone contacts. You can also make calls to landlines via navigating through your phone contacts in call history.
