Session Initiation Protocol

Session Initiation Protocol (SIP) is a control (signaling) Protocol for the application layer of Network calls and conferences. It is mainly a multimedia communication protocol based on an IP network. All the signaling functions it can implement also use RTP as the media transmission protocol. It was initially proposed by the IETF mmusic (multiparty multimedia session control) Working Group. The main functions of

Unified Communication is hard at Cisco and soft at Microsoft

When talking about the Unified Communication field, we are sure we know the contest between Cisco and Microsoft. From their own development perspective, Cisco = hardware, Microsoft = software. So two completely different methods bring different solution concepts to enterprises. What are their characteristics? Cisco and Microsoft have adopted completely different methods in the field of Unified Communication: Cisco's approach is based on network and hardware, while Microsoft's approach is "softwa

P-called-party-id header Field

A typical proxy server inserts a P-called-party-id header domain when routing INVITE requests to a destination. The header field is filled in with the request-uri of the PORXY received request. UAS identifies from several registered aors which AOR the session invitation is sent to.Users of the 3GPP IMS can obtain one or more SIP URIs (AOR) that identify the user. For example: A user can obtain a business SIP

Protocol use for Cisco Unified Communication System Architecture

We have previously introduced the overall structure of Cisco's Unified Communication call system. Now let's take a look at the core features of SIP implementation and other supported functions. We hope that the introduction and analysis in this article will help you understand this part of knowledge. Cisco deploys SIP based on RFC to implement core telephone features. To provide many SCCP-based features, Ci

Ce development: use the software Input Panel in Win CE Program Development

Introduction The software Input Panel (SIP) is a basic function of every mobile platform equipped with the wince system. It provides a means for users to input data on PDA. When talking about sip, we generally think of two points: one is the SIP itself, and the other is how to use sip in the program.

Mobile Unified Communication: unique products can survive

Unified Communication Platform, known as the Office communication Server (OCS), is integrated with Active Directory, Exchange Server, and other Microsoft products. Both IBM and Microsoft have developed smart phone clients that support Mobile users: Microsoft's Office Communicator Mobile and IBM's Lotus Sametime. Because IBM and Microsoft provide a unified communication platform, their solutions must be integrated with the infrastructure. They all rel

are their advantages and disadvantages? The most common Proxy Server only connects two UA instances. The b2bua Server is an intelligent entity and more powerful. It has some functions that proxy cannot do. It is more flexible and gradually replaces the general proxy server and becomes the mainstream of the SIP server.
