DTMF preferred on Cisco unity trunk

Can any one suggest DTMF preferred on Cisco unity trunk , any option that can resolve DTMF Inband  if telephony-event codec is removed from SBC Codec list .

In CM the general recommendation would be to use No Preference. If you have a situation with DTMF interworking the option for you is to introduce a MTP to handle the differences in available DTMF options.
