In January 17, 2013, as organizations began to focus on accelerating video communication and business processes with video functions, ATT and Polycom announced a strategic cooperation agreement to create personalized, mobile, and virtualized video conferences. With ATT Business Exchange, MPLS, Internet and mobile networks, and the Polycom RealPresence platform, both parties will use this Protocol to create

Yesterday boss threw me a polycom duo conference call and showed me how to connect to Cisco's voice phone system. After some tossing, the beans successfully registered this voice phone. Because Polycom does not support Cisco's Corp directory, I have to manually configure LDAP so that he can query the phone directory of the company's employees.650) this.width=650; "src=" http://s1.51cto.com/wyfs02/M01/76/90/

As a result, Apple TV, which is currently a hot topic in the industry, is likely to use high-frequency audio technology to demonstrate its differentiated performance. After all, there are currently not many killer jobs have. The definition of HD Audio h

know what tag should be added to the sent packet so that the vlan of the packet is the voice vlan configured for the interface connected to it? This is achieved through the LLDP protocol. The ip Phone Number communicates with the switch through LLDP. The switch sends the voice vlan of the interface to the ip phone number through LLDP protocol. 2. The voice device that does not support tags, for example, Huawei's EchoLife ET65 ip phone sends/receives packets without tags. In this case, the OUI f

H264 SVC is a technology that divides video streams into multiple layers of resolution, quality, and frame rate. It is an extension of H.264 Video Coding/decoding standard adopted by most video conferencing Devices today. Video conferencing equipment uses SVC technology to send and receive multi-layer video streams consisting of a small base layer and multiple other optional layers that can improve resolution, frame rate, and quality. This layered method can greatly improve the Code elasticity a

The switch sends the voice vlan of the interface to the ip Phone through LLDP protocol. 2. Speech devices that do not support tags, such as Huawei's EchoLife ET65 The packets sent/received by the ip Phone do not contain tags. In this case, the OUI field of the mac address of the ip phone is used to identify the pac
