Bug#843654: Use Debian pjproject and libsrtp

[Andrey Gursky]

Source: ring
Version: 20161104.4.17a0616~dfsg1-2
Severity: normal

Dear maintainer,

A week ago pjproject 2.5.5 has been made available in Debian. The same
as in ring-daemon contribs. However ring applies following patches:
endianness.patch
gnutls.patch
notestsapps.patch
ipv6.patch
ice_config.patch
multiple_listeners.patch
pj_ice_sess.patch
fix_turn_fallback.patch
fix_ioqueue_ipv6_sendto.patch

The biggest one gnutls.patch can be dropped, since packaged pjproject
can dynamically link to a SSL library. Is the rest important? If not,
then the packaged pjproject could be used already. If not, is pjproject
not really usable without them? Then they should be forwarded upstream
and for now applied in the packaged pjproject. Or there are some issues
with that? Please share the current status.

Thanks,
Andrey
