GNU Gatekeeper 5.1

Post by willamowius »

I have released GNU Gatekeeper version 5.1.

You can download it from

The main new feature in this release is H.245 multiplexing.
Together with the long supported RTP multiplexing it allows GnuGk to
handle a large amount of calls from H.460 endpoints using just 5
ports total.

Whats new ?

- support for H.245 multiplexing with H.460.18:
[RoutedMode] EnableH245Multiplexing=1, H245MultiplexPort=1722
- improved interop with Lifesize Icon (H.235), Scopia VC240 (H.460.18)
and Yealink Mobile (H.460.19)
- improved detection of neighbor gatekeeper availability
- public IP detection for Google Cloud
- new feature to let GnuGk send an event if port detection fails

There were also a number of bug fixes, please see changes.txt or the
blog post:
