There are two types of Conference bridge namely software and hardware CFB. Hardware CFB requires is hosted on cisco gateways and requires DSPs. Software CFB is hosted on CUCM, hence you do not need any hardware for this...

Meet-Me conferencing can use both hardware and software CFB but softwar CFB only supports G711 codec

Hello Hari,

Separate hardware required only when there is mixed of codec are involved. Hardware conference bridges can support multiple  low bit-rate (LBR)  stream types such as G.729 or G.723. This capability  enables some  hardware conference bridges to handle mixed-mode  conferences. In a  mixed-mode conference, the hardware conference bridge  transcodes G.729  and G.723 streams into G.711 streams, mixes them, and  then encodes the  resulting stream into the appropriate stream type for  transmission back  to the user.

There may be scenarios where you have some users configured to use G729.  In this case when these users attempt to join or use the conference  bridge resoruces, this will fail if you only have software conference  bridge. hence it i always advisable to have dsp resources on the user's  local router for hardware conference bridge.

Even in Meet-me you would require Hardware conference bridge if there are mixed of codec.Since CUCM software conference bridge can handl g711 calls.

Br,
