Can anyone give me some suggestions ?

I wanna use JSR180 & JSR 135 with Eclipse to design
a VoIP environment on J2ME , and I use prototype SDK & S60 3rd SDK
to simulate . Both of them support SIP API JSR-180, but not all JSR 135
funtions like video/audio capture ? WTK2.2 can do the recording but not
SIP API. I don't know other way to achieve the VoIP on j2ME. I think
use 180 & 135 can complete my project,but I suffer that the emulator
dosen't support all funtions like true devices.
I have to present the result to the my Prof. Am I wrong ??? I'm so helpless..
I may got fail in my final project... Give me a hand ...plz...
