Looked for a conversion tool as well for WAV/GSM ----> G.723.1. (could not find lbccodec)
Does anybody have a suggestions where to find conversion tools
Cheers Dan

I solve it for h323 in follow way: 1. Exclude all codecs except g723.1 from h323.conf:
disallow=ULAW allow=g723.1
2. Add format_g723 module (http://www.agk.nnov.ru/format_g723.c.gz) into project
3. convert all wav and gsm sound into g723 format (use lbccodec from g723_1 demo package, don't ask me where you can download it)
4. set maxsilence=0 in voicemail.conf to suppress conversion into pcm format for silence detection.
And it works fine for me. But where are some bugs in h323 module: * not supported g7231 without sound detection (simple to fix). * sometime data transfer (rtp traffic) begins before negotiation complete and first packet is going in g711 codec and channel going down (not yet reviewed).
if will any question regards format_g723 module send mail to: f723 >< agk.nnov.ru
