What kind of app are you developing that uses only SIP protocol? AFAIK,
this is just a content negotiation protocol. The actual content is
delivered using RTP. And that is another RFC that you would have to
implement. 

Even a reasonably  minimal application of the SIP protocol would involve
a number of other RFCs (like RTP), and many ITU protocols.

I cant remember if you need to do BER encoding/decoding while using SIP
(it is used everywhere in H.323 and all other ITU communication
protocols). But if you are planning to code that from scratch too, well
then ... that would real fun :)
