net-misc/asterisk-11.2.0 ebuild forcibly disables h323 and refers to Gentoo bug #360143. However, this bug report only refers to misdn. There's no mention of h323. ebuild should either re-enable h323 (as a USE flag) or explain why it's forcibly disabled.
Provide the changes to make it work on the Asterisk side and provide an updated openh323 ebuild that actually compiles. If you do, feel free to reopen. If not, then here is your explanation. 20 Sep 2011; Tony Vroon <chainsaw@gentoo.org> asterisk-1.8.5.0-r3.ebuild, asterisk-1.8.6.0.ebuild: Explicitly block against the abandoned net-libs/openh323 package in the tree. Closes bug #345635 by Grigoriy Puzankin and bug #383629 by Aidan Marks.
