 GNU Gatekeeper is an open-source project that implements an H.323
 gatekeeper. A gatekeeper provides call control services to the
 H.323 endpoints. It is an integral part of most useful internet
 telephony installations that are based on the H.323 standard.
 .
 According to Recommendation H.323, a gatekeeper shall provide the following
 services:
 .
  Address Translation
  Admissions Control
  Bandwidth Control
  Zone Management
  Call Control Signaling
  Call Authorization
  Bandwidth Management
  Call Management
 .
 The GNU Gatekeeper implements most of these functions based on the
 OpenH323 protocol stack.
