Teams are also spread out around the world today, and many workers use video conferencing solutions to remain in the loop using technologies such as SIP trunking and H.323. In the last few years, modern solutions like Zoom have become increasingly popular, but which underlying technology provides the best support for video conferencing? Rather than H.323, a growing number of meeting solutions have been using SIP for video conferencing.
SIP – Video Conferencing
SIP for video conferencing is purely based on the Session Initiation Protocol (SIP), a communication protocol that enables SIP users to create and retain, change and close data connections at the end of the session. This protocol was developed by the Internet Engineering Task Force ( IETF) more than 20 years ago and combines elements of both HTTP and SMTP.
Originally, SIP was not designed for telecoms, but thanks to its flexibility, its uses have grown over time. SIP is format-agnostic, so for video conferencing, SIP calling, messaging, texting over the internet, or file sharing, you can use a SIP connection.
SIP also enables RFC existence data, so users warn other users when they are accessible on a SIP UC network. Thanks to its ability to handle multiple link types, this makes SIP a valuable choice for unified communications solutions.
SIP is used in one-way connections known as simplex, or in both ways, known as full-duplex.
For paging, sound projection (in one direction), and video monitoring, simplex connections are helpful. Duplex is used for the above SIP or video conferencing SIP calls. SIP initiates the initial conference while using a full-duplex link for video conferencing and enables contributions to a higher with the right credentials to enter or leave at will. The hardware and software tools your team uses to connect to a media source are Voice over IP (VoIP) endpoints. There are many free solutions for video conferencing available that will function for video conferencing with SIP.
SIP vs VoIP
They are very interrelated with all of these technologies, but there are some important differences that you will need to consider. VoIP links are totally internet-based and send voice data to a target endpoint in the form of audio packets. There does not seem to be this target endpoint on the internet. The ability to connect to conventional PSTN networks at very low rates is one of the main advantages of VoIP so that local and international roaming is much more affordable than it would be with conventional telecom carriers.
SIP sends any form of media and establishes and closes the links and there is a need, so VoIP calls can also be sent using SIP. VoIP guides traffic, leading to congestion, through a single central IP network.
On the other hand, SIP provides customer agents, which are the individual systems at each end of a connection, to process any data that is transmitted. SIP is much more of a point-to-point interface for video conferencing and is less likely to encounter congestion on a single network connection.
Role of SIP in UC
SIP is designed to work with speech, video, files, and text seamlessly, so it is a very easy process to incorporate these features into a cohesive communications system. You will find SIP handling the initiation of meeting sessions, their management, and termination under all video conferencing, corporate instant messaging, and calling tech from a big UCaaS provider. For this purpose, if you deploy a SIP trunking solution for your company when you deploy UC suites in the future, you are laying the groundwork for maximized connectivity. SIP also makes integration more seamless between applications.
SIP handles the connection when using chat apps so that you click a button easily and shift the chat to a full-sized video conference with the ability to add attendees without closing the initial connection. SIP often links securely to landlines, so the team uses regular calls for video conferencing on the same network they would use for SIP.
