The example in Table 1 and Table 2 is the same as the one in Transcode G.711 to G.729A and Convert DTMF Inband Tones to RFC2833 but in addition to the transcoding G.711 to G.729A,
s must also be prepared for fax calls that are handled with G.711 on Carrier 1 and using T.38 (Fax Relay) on Carrier 2. Either
s, or Carrier 2 may detect the fax tone and initiate a modification of its media stream that agrees with the Fax Tone Treatment setting in the
