3.5.6 Dialing In From Outside the Enterprise
Dialing in Without Being Registered to a TANDBERG Gatekeeper
The feature enhancement enables dialing through a TANDBERG Gatekeeper without being
registered to it. This makes it easy to call in from a video system outside the enterprise.
It's done by dialing: EndPointAlias@GatekeeperAddress[:Port] where:
ƒ EndPointAlias: is the alias of the endpoint you want to call, the endpoint you call must be
registered with this alias on the gatekeeper
ƒ GatekeeperAddress: is either the IP-address of the gatekeeper in the form a.b.c.d (or
IPv6 a:b:c:d:a:b:c:d) or the DNS name (A/AAAA or SRV record) of the gatekeeper.
ƒ Port: is optional and gives the Q.931 port to initiate the call. The port default is 1720 and
can in most cases be left out.
Currently the SRV records _h323cs._tcp. and _h323ts._tcp. are supported.
If using an IP-address, or if not specifying the port, the default is using the normal Q.931 with port
1720.
NOTE! To be able to make such a call, this feature must be enabled in your gatekeeper or border
controller, and the called endpoint must be registered with the enterprise gatekeeper or border
controller
