  2. VoIP • VoIP Typical Architecture Media Gateway SS7/ISUP PSTN H.323 Voice Gateway ONE 400 ISDN T0/T2 IP H.323 Voice Gateway ONE 200 Softswitch Gatekeeper ISDN S0 or FXS

  3. VoIP Basics • H.323 v4 • H.323 Annex D for FAX (T38) • H.225: Call signalling channel • Q931: Call signalling • RAS: Registration, Admission, Status (with gatekeeper) • RTP/RTCP: • media streams packetization and synchronisation • H.245: Call control channel (capabilities, master/slave, logical channels) • G.7XX: audio compression algorithms

  4. VoIP Basics Q.931 Terminal Control and Management AV App Data App G.7XX • H.323 Protocol Architecture Conference Manager T.125 Terminal to Gatekeeper Signaling H.225.0 Call Signaling H.26X H.245 T.124 (RAS) RTP RTCP TPKT T.123 Unreliable Transport (UDP) Reliable Transport (TCP) Network Layer (IP) Link Layer Physical Layer

  5. VoIP Basics • H.323 Protocol Overview Registration Registration Gatekeeper RAS (UDP) Admission H.323 Terminal SETUP SETUP Q.931 H.323 Terminal CONNECT (TCP) CONNECT (H245 Address) H.245 Messages H.245 Open Logical Channels (TCP) (RTCP address) (RTCP & RTP addresses) (RTCP address) (RTCP & RTP addresses) RTP stream Media RTP stream (UDP) RTCP stream

  6. VoIP Interoperability • ONEx00 (Voice gateway) interworking with: • IP phones • Softphone on PC (Netmeeting, Openphone,…) • Interactive Voice Response server (IVR) • Multi Conference Unit (MCU) • Gatekeeper / Softswitch • Nortel CS2K, Cirpack, Italtel, Sonus, Netcentrex,… • Media Gateway

  7. VoIP: Support of H323 Gatekeepers • Use of a gatekeeper: parameters for registration • Gatekeeper identifier • Gatekeeper IP address • H.323 identifier (alias) • Gateway prefix • Alternate gatekeepers for backup • Pre-defined list (static mode) • List defined by the gatekeeper (dynamic mode)

  8. VoIP: Dialing Modes • Dialling: In-bloc ISDN terminal ONE200/400 Gatekeeper Remote End SETUP SETUP ACK INFO Digit 3 INFO Digit 0 INFO Digit 2 CALL PROCEEDING ARQ N° 302 ACF SETUP N° 302 SETUP N° 302 SETUP ACK CALL PROCEEDING ALERT ALERT ALERT CONNECT CONNECT CONNECT

  10. VoIP: FAX/Modem processing • Fax / Modem processing • Three types of devices are supported: • G3 FAX (up to V17 – 14400 bps) • Super G3 FAX (V34): processed as a Modem • Modem (up to V90) • The ONE200/400 detects the type of communication: voice, G3 FAX, Modem/SG3 Fax , (analysis of the FAX answer tone) • Requirements: • For Modem / SG3 FAX, the coder must be G.711 and the echo canceller must be disabled , SG3toG3 facility is also available to force the SG3 FAX in G3 mode • For G3 FAX: the Non Linear Processor is disabled. Transport in G.711 coding mode or FAX Relay T38

  11. VoIP: FAX/Modem Processing • In-band processing • The coder used is G.711 Selected for all the calls or for specific subscriber numbers only (routing table) • Echo canceller automatically disabled in case of Modem • NLP automatically disabled in case of G3 Fax • FAX / Modem pass-through • Direct switchover to G.711 coder upon fax and/or modem detection (called side only). ( oneway G729 to G711 fallback) or H245 request mode or TCS null or NSE RTP packets (Cisco) • Echo canceller automatically disabled in case of Modem • NLP automatically disabled in case of G3 Fax • FAX Relay T38 • V27 ter (4800 bps) and V29 (9600 bps) • T.30 messages analysis • Transparent transport for data (UDP) with optional redundancy • SG3toG3 fallback / allows to use same bandwidth for G3 and SG3 FAX

  12. VoIP: DTMF Processing • DTMF processing • Transparent mode • If G.711 coder used (Voice is not compressed, DTMF signal is transported as a voice signal) • In band transmission (RTP frames carrying the DTMF tone indication instead of voice) • RFC2833 ( dedicated RTP packets with specific packet type ) • H.245 • Use of H.245 message ( out of band transmission ) • Alphanumeric format : DTMF code. Configurable level & duration • Signal format : DTMF code + duration & level are transmitted • Detection, Suppression, Regeneration

It binds a physical port to a pots-group. Several physical ports can be bound to the same pots-group. Calls are then routed to pots-group.

  23. Logical Local Voice Port - For an outgoing Voip call, user part of From header field is based on 6C IE (calling party number) for BRI interface. For FXS port, that information must be added at the dial-peer voice pots adding “insert-calling-number”. That will be used also for 40x challenge on Invite method (to resolve user and its digest username and password.
