You need HWs DSPs...

Once you have the resources to configure transcoding, just follow these steps:
HOW TO CONFIGURE ENHANCED TRANSCODING
STEP 1: Set the interface for SCCP; este comando determina que IP va usar CCM para comunicarse con el GW.
AVVID2(config)#sccp local interface
STEP 2: Configure the CCM address; cada CCM al que el GW puede registrarse debe ser configurado con un unico identificador. La version de CCM es opcional pero si no la pones puedes tener problemas de registro con el CCM.
AVVID2(config)#sccp ccm ip_address identifier identifier_number [version ccm version]
STEP 3: Initialize SCCP; tienes que habilitar el uso de skinny en el GW.
AVVID2(config)#sccp
STEP 4: Configure the voice card to support conferencing and transcoding; recuerda de habilitar el dspfarm en la voice-card correcta
AVVID2(config)#voice-card 0
AVVID2(config-voicecard)#dsp services dspfarm
STEP 5: Create a DSP farm profile for transcoding; se puede asociar cada profile con un CCMGroup. Los profiles se asocian siempre con el commando application sccp. Es el mismo procedimiento para Transcoder y MTP, solo cambias la palabra conference por transcoder o mtp
AVVID2(config)#dspfarm profile profile_number Transcoder
AVVID2(config-dspfarm-profile)#assoicate application sccp
AVVID2(config-dspfarm-profile)#maximum sessions sessions_number
AVVID2(config-dspfarm-profile)#no shut
STEP 6: Associate profiles with CCMGroups; puedes asociar varios profiles con un CCMGroup. Cada profile debe tener un device_name unico entre 6 y 16 caracteres, que sera usado para registrate con el CCM. Este device_name debe ser el mismo que usas al agregar el Conference en CCM.
AVVID2(config)#sccp ccm group number
AVVID2(config-sccp-ccm)#associate ccm identifier_number priority priority_number
AVVID2(config-sccp-ccm)#associate profile profile_number register device_name
AVVID2(config-sccp-ccm)#bind interface interface
STEP 7: Define the resources in CallManager
