A telephone system such as small business telephone systems are connection oriented system. These system connects an internal phones of an organization. It also provides connection to different devices such as faxes, PSTN, modems, computers, extensions, etc.

They can be both. E.g. MPLS-TP or Connection-Oriented-Ethernet (COE) are connection oriented.

Connection-oriented
Connection-Oriented means that when devices communicate, they perform handshaking to set up an end-to-end connection. Connection-Oriented systems can only work in bi-directional communications environments. Connection-less means that no effort is made to set up a dedicated end-to-end connection. Walkie-talkies, or Citizens Band radios are a good examples of connection-less communication.
In connection oriented network first is confirmation of establishment of connection then only communication can take place while in connection less without establishment confirmation the communication start up.
Connection oriented is more reliable because there is an acknowledgment received from data receiver (destination) that the data is receiving and transfer is successful which is not received from connection less protocol.
Different from a connectionless protocol, a connection-oriented protocol guaranties the delivery of the information. An example of connection-oriented protocol is (TCP) and a connectionless protocol is (UDP). page/926 A+
Does a DSL connection need to go through my telephone company?
No, HTTP (Hypertext Transfer Protocol) is not a connection-oriented protocol; it is a connectionless protocol. HTTP operates over TCP, which is a connection-oriented protocol, but HTTP itself does not establish a persistent connection for communication. Each request-response cycle in HTTP is independent, meaning that after a response is sent, the connection can be closed, making it suitable for stateless transactions.
These protocols require that a logical connection be established between two devices before transferring data. This is generally accomplished by following a specific set of rules that specify how a connection should be initiated, negotiated, managed and eventually terminated. Usually one device begins by sending a request to open a connection, and the other responds ' like telephone call'.
