Hi all http://code.google.com/p/pjsip4android There you'll find the source package that can be used to compile PJSIP for Android. I've mangled the code quite a bit, and it compiles in 2 libraries - libpjlib.so and libpjlib-resample.so pjsua also compiles, as is pjsip-sine, pjsip-sndinfo, pjsip-sndtest The directory structures is considerably changed. Enjoy!
