Hi,

For H.323, you need to use a ready-made protocol stack, because it is way too complicated to write your own 'asn.1 parser' (H.323 is encoded in asn.1). Openh323 is free, and is good.

For sip, although it is ascii, is it probably still good to use a ready-made stack, e.g. vovida.

For h.323, it is probably good to download the openphone softphone (openh323.org) and then you can play around with compiling it, and making modifications.
