How is fax pass-through traffic treated over IP WAN connections that use the G.729 codec?
A. The fax traffic is demodulated and sent with VAD and echo chancellor disabled.
B. When the TGW detects the CED tone from the fax machine that has been contacted, the TGW changes to the G.711 codec with echo chancellor and VAD disabled.
C. When the OGW detects the CED tone from the fax machine that is making the call, the OGW is informed by the contacted device of the Cisco NSF features and switches to the G.711 codec with VAD disabled.
D. The contacting fax machine sends a TCF message to the contacted fax machine and waits for a CFR message. When the CFR message is received, the fax tones sent by the contacting fax machine cause the OGW to send an NSF message to the TGW, instructing it to switch to the G.711 codec with echo chancellor and VAD disabled.
