asterisk-ooh323 1:1.8.4.4~dfsg-2ubuntu4 (amd64 binary) in ubuntu precise

 Asterisk is an Open Source PBX and telephony toolkit.
 .
 This channel driver (chan_ooh323c) provides support for the H.323 protocol
 for Asterisk. This is an independent implementation that does not depend
 on OpenH323, but may be less functional than the original chan_h323.
 .
 This is one of many H.323 channel implementations for Asterisk with other
 being chan_h323, distributed by Debian as asterisk-h323.
 .
 For more information about the Asterisk PBX, have a look at the Asterisk
 package.
