Cisco will automatically do that for Cisco equipment. Any other devices, you have to configure in a more manual sense.

Makes sense. Do you have advice as to characteristics of Lync/Skype voice or video calls which would permit those datagrams and packets to be classified for expedited queue?

That's exactly the ticket. Thank you!

When a client is using Lync/Skype soft phones and Lync/Skype PBX for voice - what kind of QoS needs to be configured on the corporate network to assure prompt delivery of those real time packets? With Cisco phones the port can identify and classify the voice traffic straight away and it goes on a separate voice vlan. How do you approximate this when Lync is in play?

A router is a networking device that forwards data packets between computer networks. Routers perform the "traffic directing" functions on the Internet. The most familiar type of routers are home and small office cable or DSL routers that simply pass data, such as web pages, email, IM, and videos between computers and the Internet. More sophisticated routers, such as enterprise routers, connect large business or ISP networks up to the powerful core routers that forward data at high speed along the optical fiber lines of the Internet backbone. Though routers are typically dedicated hardware devices, use of software-based routers has grown increasingly common.

A switch is a device that filters and forwards packets of data between LAN segments. Switches operate at the data link layer or the network layer of the Open Systems Interconnection (OSI) Reference Model and therefore support any packet protocol. LANs that use switches to join segments are called switched LANs or, in the case of Ethernet networks, switched Ethernet LANs. A hub is a connection point for devices in a network. Hubs are commonly used to connect segments of a LAN. A hub contains multiple ports; when a packet arrives at one port, it is copied to the other ports so that all segments of the LAN can see all packets.

Microsoft 365 Enterprise E5 is the most feature-rich version of Microsoft 365 and consists of Office 365, Windows 10, and Enterprise Mobility + Security (EMS). It provides the collaboration, productivity, automation, and security features an enterprise customer may need to support its digital business transformation initiatives in a single stock keeping unit (SKU),
which streamlines its deployment and utilization. For companies that do not need the full feature set, Microsoft offers different versions, such as the E3 SKU at a lower price point and F1 for firstline workers.

IP telephony (Internet Protocol telephony) is a general term for the technologies that use the Internet Protocol's packet-switched connections to exchange voice, fax, and other forms of information that have traditionally been carried over the dedicated circuit-switched connections of the public switched telephone network (PSTN). Using the Internet, calls travel as packets of data on shared lines, avoiding the tolls of the PSTN. The challenge in IP telephony is to deliver the voice, fax, or video packets in a dependable flow to the user.

IP Telephony

Voice over IP (VoIP) is a methodology and group of technologies for the delivery of voice communications and multimedia sessions over Internet Protocol (IP) networks, such as the Internet. Other terms commonly associated with VoIP are IP telephony, Internet telephony, broadband telephony, and broadband phone service. The term specifically refers to the provisioning of communications services (voice, fax, SMS, voice-messaging) over the public Internet, rather than via the public switched telephone network (PSTN).  Examples of the VoIP protocols are H.323, Media Gateway Control Protocol (MGCP), Session Initiation Protocol (SIP), H.248 (also known as Media Gateway Control (Megaco)), Real-time Transport Protocol (RTP), Real-time Transport Control Protocol (RTCP), Secure Real-time Transport Protocol (SRTP), Session Description Protocol (SDP), and Inter-Asterisk eXchange (IAX).
