MjSip (standard edition) natively works on both J2SE and J2ME/CDC (actually J2ME/CDC/PersonalProfile1.0). However it is also available a porting of MjSip to J2ME/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 layers.

The porting from MjSip to MjSip2ME is very simple and can be also easily done starting from a fresh MjSip distribution following few documented steps.
