VoIP Key terms about VoIP H.323 SIP CODECs G.711 These are what G.729 everyone talks about G.723 FXS and FXO Gateway T.38 FAX What is VoIP…the technology Analog or VoIP VoIP Analog or Digital voice Gateway Gateway Digital voice IP Packets with Voice Samples circuit circuit IP Network Internet • Voice over IP (VoIP) samples 10 – 60ms of voice with an Analog-to-Digital conversion process (CODEC). This is similar to the way the phone company does it today with PCM (Voice over T1/E1). • These samples are placed into an IP packet and sent over the network. • A far-end device reassembles the voice stream on the other side. Typical VoIP System Elements Softswitch • Client Registration • Gatekeeper • Authentication • Call-Manager • Status • Softswitch • Number Mapping • Accounting • Network-Server Terminals IP Phone PSTN IP Network Gateways • PSTN, ISDN • V5, SS7 Multimedia PC • Network Interworking • User Interaction • Signaling Conversion • Dial-tone, Ringtone, etc • Media Conversion • Registers with Call Control • Packetization and reassembly • Media Conversion • ISDN, PSTN, V 5.2, SS7 VoIP Technology: Media Standards Various CODECs are used for voice compression: Codec IP BW/Call Packet Codec Comments Rate one way Length [kb/s] [kb/s] [ms] G.711 64 96 10/20 Toll quality, full rate, lowest delay G.726 16 - 40 32 - 56 20 Free: good compromise G.729 8 24 20 Licensed: best compromise G.723 @ 6.3 6.3 17 30 Licensed: low bandwidth GSM-EFR 12.2 - For Reference: mobile phones Recommend G.711 if no bandwidth limitations apply!

Fax over IP: watch out for this 1) Fax Relay, T.38 2) Fax Bypass, G.711 The Fax tones are terminated in the The Fax is carried in a G.711 voice gateway, relayed in packet form and channel just like a regular phone call. re-modulated at the far end. + Uses less bandwidth + Is interoperability with any gateway + Is reliability(offers redundancy) - Uses more bandwidth - Is less interoperable - Is less reliability T.30 Fax A/D Fax-Relay, T.38 packets D/A T.30 Fax IP Fax Bypass, T.30 Fax over G.711, 96Kb Signalling Standards Snapshot Signaling protocols defines how VoIP equipment communicate to actually set-up, establish and release telephone calls over IP networks. For example – Ring, Talk and Hang-up. H.323 The oldest and most widely supported call control protocol. Current Version is v4 (we support it now!) Is actively enhanced by the international standards community Offers the most interoperability between 3rd party equipment. Business focused SIP The newest of the call control protocols IETF (Internet based); looks like html; most extendable Messaging for all types of user devices (phones, PC, GSM) Carrier/CLEC focus We support it today! MGCP Oriented towards softswitch carrier architectures Focuses on the central site over CPE Supported in SmartNodes today! VoIP Terms Defined (1) Softswitch Call control and route server in a VoIP network providing user AAA services and intra-network call switching. This is Independent of the VoIP protocol (H.323, MGCP, SIP). Gatekeeper (GK) H.323 specific term. The GK is responsible for the management of the users (clients) and gateways in his H.323 area (zone). Implemented as software on a server or integrated as a function in a Gateway. Gateway (GW) (This is what SmartNodes do!) Signaling or Media-Gateway (may be combined in one equipment) provides conversion between different networks-protocols or technologies. H.323 Client Terminal in an H.323 network. IP-Phone or Soft-Phone (e.g. NetMeeting). AAA User Authentication, Authorization, Accounting. Required functions for a commercial VoIP Service. Carrier centric and provided by Gatekeeper. VoIP Terms Defined (2) RAS Registration Authentication Status: H.323 Sub-protocol used to register “log-in” an H.323 Gateway or Client at the Gatekeeper SIP User Agent SIP Equipment or software representing an end-user. The user agent includes a a SIP client (to initiate calls) and SIP server (to terminate calls). This is “inside” a SmartNode gateway. SIP Network Server SIP Equipment or software in the network required to register and localize User Agents and their end-users. A SIP Network Server can operate in redirect or proxy mode. This is a server box routing calls. Telephony Terms THESE YOU HAVE TO KNOW!
