10 U n i t e d N e t w o r k i n g 10 VoIP: FAX/Modem processing Fax / Modem processing  Three types of devices are supported: G3 FAX (up to V17 – 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 U n i t e d N e t w o r k i n g 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 U n i t e d N e t w o r k i n g 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
