MjSip (standard edition) natively works on both JSE (starting
from Java 1.3) and JME/CDC (actually JME/CDC/PersonalProfile1.0).
However it is also available a porting of MjSip to JME/CLDC;
it is called MjSip2ME (MjSip-to-J2ME) and runs on J2ME/CLDC1.1/MIDP2.0.
MjSip2ME differs with the standard MjSip just on the implementation
of very few classes, and offers the same APIs to the upper

be also easily done starting from a fresh mjsip distribution
following few documented steps.
