Receive, Send, View Texts from "Office Number" as well as other numbers within the organization

We receive texts to our main phone line, however only 1 person is able to view, read, respond to those messages. We need the ability to view, receive, send texts from this main line regardless of the user. This is vital for our Customer Service/Customer Experience Teams to ensure that all customers are taken care of if someone is on vacation, sick, or other reasons for unavailability.
