Hi. pjproject-1.8.10.tar.bz2 I found problems with ICE transport on Android (Samsung Galaxy S with Android 2.3) and on Ralink. I use pjsua. Trouble is in checking interface state (ip_helper_generic.c:191). When interface is actually up, it has no IFF_UP flag, but has IFF_BROADCAST, when I change interface check condition to if ((itf->ifr_flags & (IFF_UP | IFF_BROADCAST ))==0) { it works well. Pavel.
