Michael, Good question, quick answer if Zoiper supports the SILK CODEC, that is almost as good as Opus since Opus is an extension of SILK.
Your question got me looking, for a long time Digium was worried about the legal status of Opus ... they are still worried but here is the current stance: Opus for Asterisk http://blogs.digium.com/2016/09/30/opus-in-asterisk/ So, Asterisk 13 has Opus support (chan_sip ? or only chan_pjsip ? or both ?) http://downloads.digium.com/pub/telephony/codec_opus/ BUT, the binary blob "phones home" every 24 hours. I took at look at the Asterisk 13 64-bit binary blob with "ldd" $ ldd codec_opus-13.0_1.0.1-x86_64/format_ogg_opus.so linux-vdso.so.1 (0x00007fff3eb7d000) libcurl.so.4 => /usr/lib/libcurl.so.4 (0x00007fccceba7000) libc.so.6 => /lib/libc.so.6 (0x00007fccce82f000) libssl.so.1.0.0 => /usr/lib/libssl.so.1.0.0 (0x00007fccce5cf000) libcrypto.so.1.0.0 => /usr/lib/libcrypto.so.1.0.0 (0x00007fccce1cc000) liblber-2.4.so.2 => /usr/lib/liblber-2.4.so.2 (0x00007fcccdfc2000) libldap-2.4.so.2 => /usr/lib/libldap-2.4.so.2 (0x00007fcccdd90000) libz.so.1 => /usr/lib/libz.so.1 (0x00007fcccdb7e000) /lib64/ld-linux-x86-64.so.2 (0x00007fcccf02e000) libdl.so.2 => /lib/libdl.so.2 (0x00007fcccd97a000) libresolv.so.2 => /lib/libresolv.so.2 (0x00007fcccd765000) $ ldd codec_opus-13.0_1.0.1-x86_64/codec_opus.so linux-vdso.so.1 (0x00007ffed19f7000) libcurl.so.4 => /usr/lib/libcurl.so.4 (0x00007f9a73730000) libc.so.6 => /lib/libc.so.6 (0x00007f9a733b8000) libssl.so.1.0.0 => /usr/lib/libssl.so.1.0.0 (0x00007f9a73158000) libcrypto.so.1.0.0 => /usr/lib/libcrypto.so.1.0.0 (0x00007f9a72d55000) liblber-2.4.so.2 => /usr/lib/liblber-2.4.so.2 (0x00007f9a72b4b000) libldap-2.4.so.2 => /usr/lib/libldap-2.4.so.2 (0x00007f9a72919000) libz.so.1 => /usr/lib/libz.so.1 (0x00007f9a72707000) /lib64/ld-linux-x86-64.so.2 (0x00007f9a73bd6000) libdl.so.2 => /lib/libdl.so.2 (0x00007f9a72503000) libresolv.so.2 => /lib/libresolv.so.2 (0x00007f9a722ee000) The binary blobs dynamically links with libcurl but why libldap / liblber ??? Is the Opus CODEC really worth all this legal aggravation ? By contrast the SILK CODEC binary blob is straightforward: $ ldd /usr/lib/asterisk/modules/codec_silk.so linux-vdso.so.1 (0x00007fff22779000) libc.so.6 => /lib/libc.so.6 (0x00007f4ffe648000) /lib64/ld-linux-x86-64.so.2 (0x00007f4ffebf4000) If Digium is still worried about the legal situation of Opus (hence the phone home feature to limit liability) would not projects like ours have the same liability issues ?
