What is IAX protocol?

IAX (Inter-Asterisk Exchange Protocol, pronounced “eeks”) is a communications protocol for setting up interactive user sessions. IAX is similar to SIP (Session Initiation Protocol ). IAX works well in conjunction with firewalls and allows the transmission of several data channels over one link.

What is the difference between SIP and IAX?

The main difference between SIP and IAX is that IAX is a lot more efficient when utilizing bandwidth compared to SIP. Given a specific bandwidth, using IAX lets you carry a greater number of concurrent phone calls than if you used SIP. IAX achieves this by being a binary protocol and not a plain-text protocol like SIP.

What is the handshake port used by IAX2?

What protocol does VOIP use?

the Internet Protocol (IP)
Voice over IP (VOIP) uses the Internet Protocol (IP) to transmit voice as packets over an IP network. So VOIP can be achieved on any data network that uses IP, like Internet, Intranets and Local Area Networks (LAN).

Which is the second version of IAX protocol?

The original IAX protocol was not widely popular, and hence the development team came with second version of IAX commonly known as IAX2. It uses a single UDP data stream on a static port and can be used for any type of streaming media including video, but is mainly designed for IP voice calls.

What is the purpose of the asterisk IAX protocol?

IAX was developed by the open source community for the Asterisk Private Branch Exchange (PBX) and is targeted primarily at Voice over Internet Protocol (VoIP) call control, but it can be used with streaming video or any other type of multimedia. IAX is an “all in one” protocol for handling multimedia in IP networks.

What kind of data stream does Iax use?

IAX is a VoIP protocol that can be used for any type of streaming media including video, but is mainly designed for IP voice calls. IAX uses a single User Datagram Protocol (UDP) data stream between endpoints for both the session signaling and the media payloads. Thus it uses only a single UDP port number, typically 4569.
