CH A P T E R1An Overview of the Conference StationThe Cisco Unified IP Conference Station 7937G is a full-featured teleconference station that providesvoice communication over an Internet Protocol (IP) network. It functions much like a digital businessphone, allowing you to place and receive calls and to access features such as mute, hold, transfer,speed dial, call forward, and more. In addition, because conference stations are connected to your datanetwork, they offer enhanced IP telephony features, including access to network information andservices, and customizable features and services. The conference stations also support certain securityfeatures.The conference station provides a backlit LCD screen, support for up to ten speed dial numbers, and avariety of other sophisticated functions.The conference station, like other network devices, must be configured and managed. The conferencestations encode G.711a, G.711u, G.729a, G.729ab, and decode all variants of G.711 and G.729. Theconference stations also support 16-bit/16-kHz wideband audio.This chapter includes the following topics:Caution Understanding the Conference Station, page 1-2 What Networking Protocols Are Used?, page 1-4 What Features are Supported on the Conference Station?, page 1-5 Understanding Security Features for Conference Stations, page 1-7 Overview of Configuring and Installing Conference Stations, page 1-9Using a cell, mobile, or GSM phone, or two-way radio in close proximity to a Cisco Unified IPConference Station 7937G might cause interference.

Chapter 1An Overview of the Conference StationWhat Networking Protocols Are Used?What Networking Protocols Are Used?The conference station supports several industry-standard and Cisco networking protocols required forvoice communication. Table 1-1 provides an overview of the networking protocols that theconference station supports.Table 1-1Supported Networking Protocols on the Conference StationNetworking ProtocolPurposeUsage NotesCisco DiscoveryProtocol (CDP)CDP is a device-discovery protocolthat runs on all Cisco-manufacturedequipment.Dynamic HostConfiguration Protocol(DHCP)DHCP dynamically allocates andassigns an IP address to networkdevices.DHCP is enabled by default. If disabled, you must manuallyconfigure the IP address, subnet mask, gateway, and a TFTPserver on each conference station locally.DHCP enables you to connect aconference station into the networkand have the conference stationbecome operational without youneeding to manually assign an IPaddress or to configure additionalnetwork parameters.Cisco recommends that you use DHCP custom option 150.With this method, you configure the TFTP server IP addressas the option value. For additional information about DCHPconfigurations, refer to the “Cisco TFTP” chapter inCisco Unified Communications Manager System Guide.The conference station uses CDP to communicateinformation such as auxiliary VLAN ID, per port powermanagement details, and Quality of Service (QoS)Using CDP, a device can advertise its configuration information with the Cisco Catalyst switch.existence to other devices and receiveinformation about other devices inthe network.Hypertext TransferProtocol (HTTP)HTTP is the standard way ofThe conference stations uses HTTP for the XML servicestransferring information and moving and for troubleshooting purposes.documents across the Internet and theweb.Internet Protocol (IP)IP is a messaging protocol thataddresses and sends packets acrossthe network.To communicate using IP, network devices must have anassigned IP address, subnet, and gateway.IP addresses, subnets, and gateways identifications areautomatically assigned if you are using the conferencestation with DHCP. If you are not using DHCP, you mustmanually assign these properties to each conference stationlocally.Real-Time TransportProtocol (RTP)RTP is a standard protocol forThe conference station uses the RTP protocol totransporting real-time data, such as send/ receive real-time voice traffic from other conferenceinteractive voice and video, over data stations and gateways.networks.Skinny Client ControlProtocol (SCCP)SCCP includes a messaging set that The conference station uses SCCP for call control.allows communications between callcontrol servers and endpoint clientslike IP conference stations.
