For those codecs an interfaced DSP might be the only option due to lack of, or expensive software options.
I had an easier time looking into MELPe than I did with CVSD, so I looked around just a little bit to satiate my curiosity https://docs.google.com/viewer?url=http://www.compandent.com/MELPePackageFactSheetPOSIX.pdf CPU usage looks a little high. 4% of a 3.2ghz P4 to encode How many calls do you think will need to get transcoded at the same time at a given server? With asterisk the g729 codec has hardware and software options so people have a choice as to how much g729 they get. >From http://www.compandent.com/melpe_faq.htm#Q09.6 9.6 Q: Do you offer high density MELPe boards (say 100-200 channels) for VoIP Servers or Gateways? A: Yes, Compandent and one of our partners offer up to 240-port, 6400 MIPS, DSP PMC (PCI Mezzanine Card) form factor utilizing C5441 DSPs with on-board 400 Mhz PowerPC. A fully embedded telephony software library is also available for VoIP, V.22 and V.90 Modem, Fax, Conferencing, Telephony, MELPe and more. For more details please call us or contact us. </quote> I was all "yea!" until I hit up wikipedia for information on PCI Mezzanine cards http://en.wikipedia.org/wiki/PCI_Mezzanine_Card and clicked one of the links to a picture, but maybe somebody makes an adaptor.
