* T30 fax session consists of 5 phases:
*
* 1) Phase A "Call Establishment"
* Off-hook, Dialing, Ringing, Answering, CNG and CED Tones
*
* 2) Phase B "Pre-Message Procedure"
* Fax Terminal Identification, Capabilities exchanged and Set, Training
*
* 3) Phase C "In-Message Procedure, Message Transmission"
* Transmission of Pages, Line Supervision, Error Detection and Correction
*
* 4) Phase D "Post Message Procedure"
* End-of-Message Signaling, Page Confirmation
*
* 5) Phase E "Call Release"
* Call Disconnect and Return to On-hook State
