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/
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.

I. Overview
Review the video surveillance market, the monitoring platform system used by the signaling control protocol is not unified, resulting in the interconnection of the technical threshold. This is a bit similar to the 80 's China's switch market eight system of the situation. These reasons hinder the network era of large-scale carrier-level video surveillance, remote access, centralized management needs. The industry has explored two ways to solve the problem:

Introduction
Communication providers and their partners and users are increasingly eager for a new generation of IP-based services. Now we have the SIP Session Initiation Protocol. SIP was born less than a decade ago in the computer science laboratory.
It is the first protocol suitable for multi-user sessions in various media content. Now it has become the specification of the Internet Engineering Task Gro

SIP (Session Initiation Protocol) Conversation Initiation Protocol is an application layer control (signaling) protocol for network telephony and conferencing. It is mainly a multimedia communication protocol based on IP network. It can realize the signaling functions are also using RTP as a media transmission protocol. Originally presented by the IETF Mmusic (multiparty multimedia session control) workgroup.

1. Introduction to the SIP protocol
Many applications on the internet need to establish and manage a session. The session here refers to the exchange of data between participants. Considering the actual situation of participants, the implementation of these applications is often very complicated: Participants may move between agents, they may have multiple names, the communication between them may be based on different media (such as text, multimedia,
Basic SIP Application
As one of the main VOIP communication protocols, the SIP protocol is simple, flexible, and open, and is gradually dominant in the VOIP communication field. The main methods used for SIP Communication include SIP terminals, proxy/targeted servers, location servers, and PSTN gateways. Currently, th

1. How is the SIP coming and how is it constructed?
In general, SIP is a lightweight signaling protocol, which can be used as a signaling for audio, video, and timely information.

A session refers to the communication of voice, video, and other media forms between two or more users, possibly IP telephony, conferencing, instant messaging, and so on.SIP is a signaling protocol that corresponds to a call signaling protocol (such as SS7 ISUP) in a traditional telephony network.
