Ekiga doesn't use libavcodec directly, so just having libavcodec-unstripped around isn't enough.
Instead, Ekiga's codecs are distributed as plugins built by libopal, which has to be built against the unstripped-dev package.
bojo42 has packaged all of the codecs that he could (h264 and ilbc, see his ekiga ppa) but he couldn't do h263 without unstripped-dev
