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 Features Module Describes SIP features that are implemented in Sip Features Module and not in ysipchan SIP Methods How Yate process SIP request methods and how to enable methods that are not handled by default. SIP Routing in Yate Configure a SIP channel or a SIP line. SIP Configuration File Main configuration file for SIP module in Yate.

SIP Features SIP Features Module Describes SIP features that are implemented in Sip Features Module and not in ysipchan SIP Send DTMFs This page describes DTMFs send related configuration of SIP channel. SIP Attended Call Transfer In Cluster Describes how to configure Yate to handle a SIP attended call transfer for an unknown call leg. SIP Flood Protection Shows how 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 providing security for the internal network of the carrier. SIP Client How to build a SIP Client in Yate used as a Client 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. 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
