asterisk-ooh323 1:20.4.0~dfsg+~cs6.13.40431414-2 (arm64 binary) in ubuntu mantic

 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.
 .
 For more information about the Asterisk PBX,
 have a look at the Asterisk package.
