Using DialNewCall being self signed

Hi developers,

Can i DialNewCall() while being self signed ? DialNewCall need Network Services as capability.

As i understand Netwok services can be used as a blanket to make a GPRS/3G connection only. To use other servcies like DialNewCall() it has to be symbian Signed.

If i do put NetworkServices in my mmp i get a error "Menu: Unable to execute file for security reasons". This is on launch of application.

I build by application on command line. After i have added NetworkServices to the mmp, I have cleaned the build and rebuilt it again.

If i dont put NetworkServices the application works fine except DialNewCall. The application just does not do anything when i try to make a call.

I need quick help on this guys.

Any kinds of hints will also be great.

Thanks,
