Telephony

Yate is a telephony engine who's main function is to connect together call legs to external devices or to internal server resources. It uses a variety of VoIP protocols(as SIP, H.323, IAX2 or Jingle) that can be used without the need of special hardware. In the next chapters you will find more informations about configuring each telephony protocol and the features supported by Yate.

Session Initiation Protocol(SIP)

The Session Initiation Protocol(SIP) is an signaling protocol widely used for controlling communication sessions such as voice and video calls over Internet Protocol(IP).

About SIP SIP in Yate Describes the implementation of the SIP protocol in Yate and some SIP features. SIP Listeners in Yate Listeners (TCP, UDP, TLS) specify on which network interfaces to listen. SIP Methods How Yate processes SIP request methods and how to enable methods that are not handled by default. SIP Features Module Describes SIP features module that implements SUBSCRIBE and NOTIFY methods SIP Routing in Yate Route to a SIP channel and a SIP Line. SIP Configuration File Main configuration file for SIP module in Yate. SIP Client Implementation and SIP Client features in Yate

SIP Features SIP Features Module Describes SIP features module that implements SUBSCRIBE and NOTIFY methods SIP Send DTMFs Describes configurations related to DTMFs in SIP channel. SIP Attended Call Transfer In Cluster How to configure Yate to handle a SIP attended call transfer for an unknown call leg in the cluster node SIP Flood Protection Yate provides a protection mechanism against several types of SIP flood attacks. SIP SBC Describes how Yate can be used as a SIP session border controller. SIP Generic Message The message and his syntax generated by the ysipchan module on receiving the specified requests. xsip.generate Another SIP message sent by the ysipchan module requesting the transmission of a SIP request. is a message sent by a module requesting the transmission of a SIP reques SIP query for CNAM and LNP Another SIP feature used in a routing module that allows Yate to query Name and Local Number Portability databases over the SIP protocol. SIP NAT Describes how Yate as a SIP Server can pass the voice (RTP) as a NAT.

H323

H.323 is a standard that specifies the components, protocols and procedures that provide multimedia communication services - real-time audio, video, and data communications - over packet-based networks.

Media Gateway Control Protocol(MGCP)

Media Gateway Control Protocol is a signalling and call control protocol used within Voice over IP (VoIP) systems that typically inter-operate with the public switched telephone network (PSTN).

About MGCP MGCP call agent module This module implements the Call Agent part of MGCP allowing Yate to control analog or digital Media Gateways

MGCP Features Configuring Mediant MGCP How to configure Yate with Mediant MGCP Configuration for a Mediant MP-114 FXS analog gateway How to configure Yate to use a Mediant MP-114 FXS analog gateway

Inter-Asterisk eXchange(IAX/IAX2)

IAX2 is a VoIP protocol that carries both signaling and media on the same port.

About IAX IAX Explanation how the connection works with trunked packets

IAX Features Yate as IAX server and YateClient as IAX client Setup to configure Yate as a IAX Server and YateClient as a IAX client Connecting To IAXTEL Setup for connecting to IAXTEL

JINGLE

Jingle is an extension to the Extensible Messaging and Presence Protocol (XMPP) which adds peer-to-peer (P2P) session control (signaling) for multimedia interactions such as in Voice over IP (VoIP) or videoconferencing communications.
