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 ModemModem (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

Logical Local Voice Port

One Dial-peer voice POTS must be configured for each physical voice port.

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.

3 - Internal Local Voice Port (POTS)

23


CLI(configure)# dial-peer voice pots <id>CLI(pots)# pots-group <id> CLI(pots)# port 5/<port>CLI(pots)# insert-calling-number <E164 number>CLI(pots)# no shutdownCLI(pots)# exit


- 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.
