Probably, if you still don't have a solution I found this:
I haven't tried it but it looks promising since it has a J2ME version.

sip is not the problem, and adjusting mjsip works quite good, needs connection handling etc.
the problem is recording and playing at the same time, with an efficient codec and without gaps.
this is quite frustrating to develop i guess - my company decided to wait for a 3rd party solution and I don't do any development in this area any more.
we are currently evaluating a product from fellow board expert myraddin, it works very well in their setup (and they have a nice youtube video) but I have not managed to run it yet. you can find more at http://www.fgmicrotec.com/
agito has also announced working voip quite some time ago, they offer it as a complete solution (thus not interesting for us). dunno if their product works or which limitations they face.

Good point, forgot about the "play & record at same time" problem.

Well of course it is. This topic remains universally interesting for all interested parties
Hmm... yea you forgot about that small detail of real time full duplex

i think it is better to develop sip signaling from scratch because this open source material is not perfect for mobile device..they use hudge resource....just first make a sip message parser ..then make the register part and then do the signaling and rtp part.
