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
E.711 codec with echo chancellor and VAD disabled.
