Chapter 11 Using a gatekeeper

Why use a gatekeeper

You can use a gatekeeper with an MCU, IP VCR or ISDN Gateway. A gatekeeper allows you to:

 Dial endpoints using directory numbers (E.164 number) or names as well as IP addresses. Equally,

endpoints can dial directly in to conferences or recordings using directory numbers

 Use service prefixes to aid routing of calls

 Balance the load of one conference - see “The IP VCR has one auto attendant that allows you to select a

recording to play back or start recording. Go to Settings > Gatekeeper to set the auto attendant

gatekeeper ID. See the online help topic “Displaying gatekeeper settings”.” on page 59

(However, if you do not want to use a gatekeeper because of the cost, the initial setting up which can be

complicated or because you want to keep the items of equipment to a minimum, you can still cater for most

video conferencing requirements.)

Registering a unit with a gatekeeper

If you are intending to use a unit with a gatekeeper go to Settings > Gatekeeper to enable gatekeeper

usage on the unit. Then identify both the gatekeeper to be used and the ID by which your unit will be

known to the gatekeeper. Many of the fields are the same irrespective of unit type but also there are unit-

specific fields. See the online help topic “Displaying gatekeeper settings” (MCU and IP VCR) or

“Configuring gatekeeper settings” (Gateway).

Registration types (MCU and IP VCR)

An MCU or IP VCR unit can be registered with a gatekeeper as one of a number of types. Getting the type

correct is important and depends on the unit, gatekeeper you are using and whether you want to use a

service prefix. See the online help topic “Displaying gatekeeper settings”.

Each unit can only register with one gatekeeper.
