GNU Gatekeeper 3.4

Highlights and new features:

implement H.460.26 (RTP over TCP)
together with H.460.17, this allows endpoints to operate on a single outbound TCP connection

implement H.235.6 media encryption of data channels

automatically update H.235.6 media keys after 2^31 packets
enable with EnableH235HalfCallMediaKeyUpdates=1

implement TLS support to encrypt call signaling channel
important to secure the H.235.6 key exchange, allows a fully encrypted GnuGk-to-GnuGk trunk

set RTP source IP on OS that support it (Linux, FreeBSD, Win Vista+)
important for multi-homed servers with H.460.19 or IP failover

new routing policy 'ldap'

new authentication modules: LDAPAliasAuth and LDAPPasswordAuth

ability to send post dial digits after call connects

allow non-gateways to use additive registration, fix H.460.x support
now always enabled and important for LifeSize interoperability

new accounting variables %{caller-vendor} and %{callee-vendor}

allow "0.0.0.0/0" in ModeSelection and ExplicitRoutes=
this allowes you to set one default setting and other rules for exceptions

access to the SSH status port can be restricted by additional IP rules in [GkStatus::Auth]

setting on/off config switches to y/n or a/? is now depricated, use 1/0
check your config, these will stop working shortly!

a number of bug fixes

Please note that not all executables have all features compiled in. Especially if you want good SNMP support, you should compile GnuGk for your specific OS distribution.
