Two things about SIP for push (rather than IMS or VOIP) 1) SIP also runs on TCP (does not require UDP).
2) For a SIP server you can use SIP Servlets (link for implementation given above) which should run on probably all servlet containers (Tomcat, Jetty, JBoss, etc.). BTW - looking a bit closer at JAIN SIP one issue is that it is quite large. The APK for the sample application you mentioned (jeanderuelle.blogspot) is 1.3 MB and that is a minimal example. Most of the size is the JAIN classes.
