The profile is not negotiating t.38, it clearly shows g711u.

profile voip default
  codec 1 g711ulaw64k rx-length 20 tx-length 20
  codec 2 transparent-clearmode rx-length 20 tx-length 20
  no dtmf-relay
  rtp traffic-class local-default
  no dtmf-mute-encoder
  response-preferred-codec g711ulaw64k
  dejitter-mode static
  media detection-timeout 5
  fax transmission 1 relay t38-udp
  fax volume -13.5
  fax dejitter-max-delay 60
  modem dejitter-max-delay 60
  no modem detection on-remote-fax-request

Try that on The 4424.
