5.7.4.5.4. Usage Guideline
DTMF is the tone generated when you press a digit on a touch-tone phone. This
tone is compressed at one end of a call; when the tone is decompressed at
the other end, it can become distorted, depending on the codec used. The
DTMF relay feature transports DTMF tones generated after call establishment
out of band using a standard H.323 out-of-band method.
The dtmf-relay command determines the outgoing format of relayed DTMF
tones. The gateway automatically accepts all formats.
