Hi, I'm trying to integrate a ZRTP implementation to PJSIP and i have found two alternatives: ZORG and ZRTP4PJ. Applying ZORG patch to PJSIP 1.10 fails (at their site states its tested with PJSIP 1.8.5 and using PJSIP 1.8.5 its a "last resort" for me) so i turned to ZRTP4PJ; They provide a patch for PJSIP 1.10 and it works, but still don't know how to integrate it. My development environment includes Windows/Carbide and the target platform is Symbian. I'm following ZRTP4PJ instructions: 1- copied the ZRTP4PJ directory to PJSIP's third_party directory 2- patched de pjsip source with the provided diff 3- Downloaded the openssl headers (required by ZRTP4PJ) 4- Adjusted the PJDIR variable at ZRTP4PJ's MakeFile ($PJDIR/third_party/build/zrtp4pj/Makefile) And i think i should make a new mmp file for ZRTP4PJ for Carbide to "see" ZRTP4PJ but i'm not sure. Just calling: make dep make in ZRTP4PJ build directory (as suggested by ZRTP4PJ) doesn't work since my PJSIP working copy has got built only by Carbide. (so it lacks some .mak that should be generated by a previous "manual" build of pjsip.) Please, could anyone give me any hints/suggestions/corrections on what should i do exactly to get ZRTP4PJ integrated with PJSIP for symbian (or some other way to get zrtp into pjsip) thanks,
