SIP (Session Initiation Protocol, conversational initial protocol) was developed to help provide advanced telephony services across the Internet. Internet telephony (IP telephony) is evolving into a formal business telephony model, and sip is an important part of the NGN (Next Generation Network) family of protocols needed to ensure this evolution.

Preliminary Exploration of OsipToday, we started to study the SIP protocol, called Session Initiation Protocol, which is a required protocol in VoIP.First, I found the RFC document, rfc3261, and more than 200 pages of English documents, which is too slow to read. Later, I found it was said that it was Huawei's internal sip training materials, or the Chinese language was good, and I had a general understandi

Haha, I had a lot to do with what I used to do. Basically, I used to develop the SIP protocol stack based on Osip, exo

Session Initiation Protocol (SIP) is the biggest winner in the VoiceCon IP Phone exhibition held this week. Some vendors have announced the launch of SIP-based upgrade products or added support for this security protocol to their existing products.SIP is a single signaling and Event Notification protocol that combines voice, video, and message communication. This Protocol also provides a standard-based appr

SIP is an application control signaling protocol proposed by IETF. As the name implies, it is used to initiate a session. It can be used to create, modify, and end multimedia session processes attended by multiple participants. Participants can communicate with each other through multicast, unicast, or network connection. There are clients and servers in the SIP. A client is an application that establishes

In the previous article, we analyzed the process of registering a message with a sip service. Next we will analyze the process of processing an invite request. From the handle_request_invite entry, the invite request processes the replace Request Header here. If it is replace, it is considered to be consulting. At this time, no new channel is created, but a channel is found (masqued ), in most cases, a new request is created based on invite. Therefor

SIP response code The response code is included, and the HTTP/1.1 response code is extended. Not all HTTP/1.1 Response codes are properly applied, but only pointed out in the discount. Other HTTP/1.1 Response codes should not be used. In addition, SIP also defines a new response code series, 6xx. 1. Temporary response 1xxA temporary response, that is, a message response, indicates that the other server is

The integration of unified communication involves software, hardware, mobile devices, and fixed devices. The standards and protocols are different. Therefore, the integration is difficult. In terms of IP phones and desktop applications, there are mainly SIP and H.323 Protocols; mobile videos are H.324M; Monitoring also includes H.323, SIP and proprietary protocols as well as MEPG2, MEPG4, and H. 264 and ot

First, we will briefly introduce the SIP protocol, which is a Session Initiation Protocol and mainly used for network multimedia calls. The sip api can be called only in android2.3 or later versions, and the device must support the sip before making a SIP call. The APIs used by SIP
