1 To enable experimental voice support in SIPE (only on platforms where libpurple
2 supports voice & video):
4 - libnice >= 0.1.0 and farsight2 >= 0.0.23 are required
5 - source tree of Pidgin 2.7.10 or higher is required and following patches must
7 - purple_media_get_active_candidates.patch
9 - compile SIPE source, check that voice support is enabled in configure output
10 - If you get errors on incompatible encryption levels when making a call, change
11 to peer's registry is needed to allow unencrypted media transfer; use the
12 attached .reg file. Encryption can be also already set as optional, depending
13 on your domain policy configuration, in this case registry change is not needed.
14 - now you can try to make a voice call
16 STATUS OF PATCHES IN UPSTREAM
17 =============================
19 purple_media_get_active_candidates.patch
20 - reported as http://developer.pidgin.im/ticket/11830
21 - commited for future 2.8.0 release
24 - reported as http://developer.pidgin.im/ticket/12981
25 - accepted for future 2.8.0 release
27 Biggest show stopper now is a lack of SRTP (encrypted transfer) in Farsight library,
28 requiring Office Communicator users to change their registry settings as a
29 workaround is unacceptable. According to FS website, someone is working on
30 this, but no results are available so far. UPDATE: in some environments unencrypted
31 calls can be allowed by domain policy, so not all users are affected.
