Phone Windows phone 8 pjsip integration

Hello guyz,

Im actually trying to built a pjsip client for windows phone 8. pjsip has a library developed for windows phone 8 with a cli application.
but they dont have any sample app which works as a client in windows phone 8,like they have on android like csipsimple,for ios,siphon.

their documentation doesnt help either,so far ive managed to run their library with the cli application,but i need some help on how to use it in my own app without the cli option,with gui may be.

right now,all i need is some headstart on how to integrate the pjsip library with my gui project and register or make call using the library.

any help,documentation,headstart will be immensely helpful.

Thanks in advance
