BACKGROUND CONTEXT TECHNOLOGY

Traditional telephony networks

IP telephony, the first step of the convergence of information systems (video / unified messaging voice / data / / sharing documents)

The reference models of ToIP

  • Peer to Peer Model
  • master / slave model
  • architectures and components of NGN solutions (MGC (Media Gateway Controller) , MG (Media Gateway) , Signalling Gateway , IP -PBX , ... )

Coding (voice and video)

  • the voice encoding ( G.711, G.729 , ... )
  • video coding
  • different transport networks ( ADSL , PPP , FR , Ethernet, ... )

Transport mechanism / voice RTP RTCP

TECHNOLOGY

Brief History of SIP

  • standardization bodies ( IETF , SIP Forum ...)
  • the reference model applicable to SIP (Peer to Peer)

Presentation of a basic SIP call

  • with knowledge of the destination IP address
  • without knowledge of the IP address of the recipient ( Registration and called using a proxy by the caller)
  • release the call

The architecture and the components of SIP

Components

  • User Agent (UAC , UAS)
  • Registrar
  • Proxy server (Stateless , Stateful , Forking ...)
  • redirect Server
  • rental server
  • Using the DNS
  • Gateway ( SIP / PSTN, SIP/H.323 , SIP / MGCP , ... )

The protocol stack (UDP, TCP , IP, SDP , RTP , DHCP, DNS)

  • the syntax of SIP messages
  •  the header structure / body
  •  queries
  • responses / errors
  • header fields of header

Addressing

  • URI
  • E164
  • ENUM : correspondence SIP address / phone number using DNS

Dynamic SIP

  • transactions
  • call flows
  • call AU busy
  • interrupted before dropping appeal
  • call from a SIP phone to the PSTN via a gateway
  • secure messages ( timers, Cseq , PRACK optional)

SDP for negotiating media streams

Using re-INVITE or UPDATE for re- negotiation of flow

Routing SIP

  • using the field 'through'
  • using the DNS proxy
  • Keystone signaling field 'contact'
  • Use headers 'Record- Route', 'route'

Services can add value with SIP (not exhaustive)

  • Message Waiting Indicator (Message Waiting Indication)
  • Conferences (Pre -arrange or Ad- hoc)
  • Call Forwarding
  • Warning / Hold
  • Call termination on occupation
  • Call Transfer
  • Find Me / One number follow me
  • Click to dial

Fax transmission and DTMF SIP

  • DTMF inband and out- of-band
  • FAX via T.38 or G.711

SIP security

  • SIP and NAT
  • SIP Firewall
  • HTTP digest authentication
  • encryption of RTP (SRTP) with SDP
  • the signaling encryption : TLS (sips URI , using AES)
  • managing encryption keys with MIKEY

Instant messaging and presence

  • the use of SUBSCRIBE and NOTIFY messages (Agent co-located)
  • using PUBLISH (Distributed Agent)
  • the message SIMPLE MESSAGE

Comparative table of SIP / H.323, H.248 ( MEGACO ) , MGCP , proprietary protocols

Limitations of the SIP protocol , possible changes
