Have you considered any existing free SIP phone for windows?

E.g: http://www.sflphone.org/

An informational RFC that just came out may be of interest
to you

   RFC 4504
   Title:      SIP Telephony Device Requirements and
Configuration
   Author:     H. Sinnreich, Ed., S. Lass, C. Stredicke
   Status:     Informational
   Date:       May 2006
   URL:        http://www.
rfc-editor.org/rfc/rfc4504.txt

   This document describes the requirements for SIP
telephony devices,
   based on the deployment experience of large numbers of
SIP phones and
   PC clients using different implementations in various
networks. The
   objectives of the requirements are a well-defined set of
   interoperability and multi-vendor-supported core
features, so as to
   enable similar ease of purchase, installation, and
operation as found
   for PCs, PDAs, analog feature phones or mobile phones.

   We present a glossary of the most common settings and
some of the
   more widely used values for some settings. This memo
provides
   information for the Internet community.
   

If  nothing else you should browse section 3 "Glossary
and Usage for the
Configuration Settings" for ideas on what to name your
settings.

Why not create libsip from the asterisk code and integrate
it into one 
of the existing windows sip phone OSS projects?
