How many Free VoIP protocols other than SIP?
there are other protocols for VoIP besides SIP. Here are some examples:
-
H.323: This protocol was developed by the ITU-T and was widely used for VoIP in the 1990s and early 2000s. It provides similar functionality to SIP, but with a different set of standards and protocols.
-
MGCP: Media Gateway Control Protocol (MGCP) is a protocol that is used to control media gateways in a VoIP network. It is different from SIP in that it separates call control functions from media gateway functions.
-
SCCP: Skinny Client Control Protocol (SCCP) is a Cisco proprietary protocol used for VoIP communication between Cisco devices. It is commonly used in Cisco Unified Communications Manager (CUCM) deployments.
-
IAX: Inter-Asterisk eXchange (IAX) is a protocol developed by Digium, the company behind the Asterisk PBX system. It is designed to simplify the setup and management of VoIP connections between Asterisk servers.
-
RTP: Real-time Transport Protocol (RTP) is not a call control protocol like SIP or MGCP, but it is used to transport voice and video data in a VoIP network. It works in conjunction with other protocols like SIP or MGCP to provide end-to-end VoIP communication.
Each of these protocols has its own set of advantages and disadvantages, and the choice of protocol depends on the specific requirements and preferences of the VoIP system being implemented.
SIP, H.323, MGCP, SCCP, IAX, and RTP are open standard protocols and do not require a licensing fee to use.
However, some specific implementations or products that use these protocols may have licensing fees associated with them, so it’s important to check the licensing requirements for any specific product or implementation you may be considering.
In general, open source implementations of these protocols, such as Asterisk for SIP and IAX, are likely to be free to use.
What is the difference between SIP and Cisco SCCP protocol?
-
Architecture: SIP follows a distributed architecture, which means that there is no centralized control point for call processing. SCCP, on the other hand, follows a centralized architecture, which means that there is a centralized call control point (such as a Cisco Unified Communications Manager) that manages all call processing.
-
Functionality: Both protocols provide similar functionality, such as call setup, tear down, and media handling. However, SIP supports a wider range of features and extensions, such as presence, instant messaging, and video conferencing.
-
Interoperability: SIP is widely adopted and interoperable with many different VoIP systems and devices from various vendors. SCCP, on the other hand, is only used in Cisco VoIP systems and is not interoperable with non-Cisco systems.
-
Configuration: SIP devices can be configured using standard configuration files or web interfaces. SCCP devices require specific configuration files and use Cisco’s Unified Communications Manager for configuration management.
Overall, SIP is a more widely adopted and flexible protocol that can be used with a variety of VoIP devices and systems, while SCCP is specific to Cisco VoIP devices and systems.
What VoIP protocols are Social apps used like Skype, Line, Instagram, Telegram?
-
Skype: Skype uses its own proprietary VoIP protocol, which is based on peer-to-peer networking technology. The protocol uses a combination of audio and video codecs to support high-quality voice and video calling.
-
Line: Line uses a combination of proprietary protocols and industry-standard protocols such as SIP and RTP to support voice and video calling. The app also uses a custom codec called Opus for audio compression.
-
Instagram: Instagram uses a combination of protocols such as WebRTC, RTP, and SRTP to support voice and video calling. The app also uses a custom codec called IG Audio for audio compression.
-
Telegram: Telegram uses a custom VoIP protocol called MTProto to support voice and video calling. The protocol is designed to provide high levels of security and privacy for users.
It’s worth noting that these protocols are not standardized or openly available, and are specific to each app’s implementation.
