Configuring gatekeeper settings

To configure gatekeeper settings, go to Settings > H.323.

You can configure the IP VCR to use a gatekeeper, which can make it easier for end-users to watch and make recordings using directory numbers rather than requiring them to know the IP address or host name of the IP VCR.

Note that recording IDs, recording console IDs, and auto attendant IDs are properties of folders (refer to Understanding the folders list) and can all be registered with the gatekeeper. To register these IDs with the gatekeeper, select Register folder IDs. For more information, refer to the table below.

On this page:

Gatekeeper settings

Refer to this table for assistance configuring the gatekeeper settings. After making any configuration changes, click Apply changes.

 

Field Field description Usage tips
H.323 gatekeeper usage

Enables the IP VCR to use an H.323 gatekeeper for registration of numeric IDs of recordings, and for recording IDs, recording console IDs, and auto attendant IDs of folders.

When set to Disabled then no gatekeeper registrations are attempted (and existing registrations are torn down), regardless of other gatekeeper or per-recording settings.

When set to Enabled registrations with the gatekeeper are attempted, and the gatekeeper is contacted for incoming and outgoing calls. If the gatekeeper does not respond, calls are still connected if possible. When set to Required registrations with the gatekeeper are attempted but calls are not connected if the gatekeeper cannot be contacted.

H.323 gatekeeper address

Identifies the network address of the gatekeeper to which IP VCR registrations should be made.

This can be specified either as a host name or as an IP address.

This field will have no effect if H.323 Gatekeeper usage (see above) is set to Disabled.

The gatekeeper can be either the built-in gatekeeper enabled on the Gatekeeper page (see Displaying the built-in gatekeeper registration list) or an external gatekeeper. To use the built-in gatekeeper enter "127.0.0.1". For an external gatekeeper, enter its host name or IP address.

Gatekeeper registration type

Controls how the IP VCR identifies itself when registering with its configured gatekeeper.

Cisco recommends that you use the Terminal / gateway option unless you are using a service prefix or point-to-point prefix (in this case, use Gateway). Only use a different option if you are:

  • having specific problems
  • using the Cisco Gatekeeper (with or without a service prefix), in which case use Gateway (Cisco GK compatible)
  • using the VCON MXM Gatekeeper (with or without a service prefix), in which case use Gateway

In particular, if you are using the Deregister recording prefixes when all recording ports are in use setting (below), set the Gatekeeper registration type to Gateway (and on your gatekeeper, set gatekeeper call routing to "direct call" mode).

Refer to the list of Knoweldgebase in the Support section of the web site for more details about interoperability with gatekeepers.

Ethernet port association

Whether a call involves consultation with the configured gatekeeper also depends on the Port A and Port B settings. For all incoming calls, and outgoing calls dialed by address rather than by E.164 phone number, the gatekeeper is used to validate the connection only if the network port over which the connection is made is selected here.

 

(Mandatory) H.323 ID to register

Specifies an identifier that the IP VCR can use to register itself with the H.323 gatekeeper.

Before the IP VCR can register any recordings with the H.323 gatekeeper, it must make a unit-wide/blade-wide registration.

This field is required for gatekeeper registration. It will have no effect if H.323 gatekeeper usage is disabled.

Use password

If the configured gatekeeper required password authentication from registrants, select Use password and type in the password.

Note that where password authentication is used, the (Mandatory) H.323 ID to register will be used as the username.

Prefix for IP VCR registrations

Specifies an optional group of digits that can be used as a prefix in either (or both) of the following ways:

  • use as prefix for registrations: the numbers are added to the beginning of each recording's Numeric ID (or any of a folder's IDs) before registering it with the H.323 gatekeeper (you must have selected register with H.323 gatekeeper in the recording's settings). For example, if a recording has a numeric ID of "2222" and the registration prefix is "99", then the recording will be registered with the gatekeeper with a gatekeeper ID of "992222"
  • register as a service prefix: the numbers are used as a service prefix for the IP VCR on the gatekeeper. That means that any number beginning with the prefix will be directed to the IP VCR. Any numbers following the prefix will be identified by the IP VCR as a recording number (or folder ID). For example, if a recording has Numeric ID "3333" and the IP VCR has a service prefix of "99" registered with the gatekeeper, then a user dialing "993333" will be directed to that recording

This setting does not affect point-to-point calls for which prefixes can be set on a per-folder basis (see Adding and updating folders).

Recordings registered with a gatekeeper have a unique number that can be entered from a video conferencing endpoint to connect directly to the recording. This eliminates the need for users to navigate the auto attendant or to know the IP address of the IP VCR.

Folders registered with a gatekeeper have:

  • an auto attendant ID that can be entered from an endpoint to connect directly with the auto attendant of that folder
  • a recording console ID, that will start up the recording console
  • a recording ID that will cause the IP VCR to start a recording and place it in the folder associated with that recording ID

Using registration prefixes:

  • To usefully partition the dialing space, you might need to ensure that all recordings registered with a gatekeeper from a single IP VCR start with the same sequence of digits

    Using registration prefixes also can benefit large-scale dial plan changes. For example, you can change all IP VCR registrations to begin with "121" instead of "11" by changing a single IP VCR configuration field rather than individually amending every recording's associated gatekeeper ID

  • If you want to use folder IDs in conjunction with a registration prefix, select Register folder IDs further down the page

Using service prefixes:

  • By using a service prefix, the gatekeeper will automatically forward calls starting with the service prefix to the IP VCR. The IP VCR will determine whether the call matches a valid recording (in which case the recording will be played back), folder ID (in which case the call will be recorded into that folder) or an auto attendant ID (in which case the auto attendant is displayed). If no match is found, the default incoming call action will be applied (see Configuring global connection settings). You do not have to individually register recordings or folder IDs with the gatekeeper

These settings will have no effect if H.323 gatekeeper usage is disabled.

Play back prefix

Specifies an optional extra prefix that the IP VCR should register with the H.323 gatekeeper specifically for play back.

See Deregister play back prefix when all play back ports are in use below.

Deregister recording prefixes when all recording ports are in use

When selected, configured recording prefixes (both the Prefix for IP VCR registrations if used as a service prefix and the Point-to-point call incoming prefix set for any folders) will be deregistered when all recording ports are in use on the IP VCR.

This setting is for use in load-balanced environments. By deregistering the recording prefixes of one IP VCR, the gatekeeper will contact another IP VCR that is registered with the same prefix(es), if necessary, when users call the prefix to make new recordings.

Deregister play back prefix when all play back ports are in use

When selected, the IP VCR will deregister the configured Play back prefix from the H.323 gatekeeper when all play back ports are in use.

This setting is for use in load-balanced environments. By deregistering the play back prefix of one IP VCR, the gatekeeper will contact another IP VCR that is registered with the same prefix, if necessary, when users call the prefix to play back a recording.

Register folder IDs

When selected IDs associated with all folders will be registered with the H.323 gatekeeper.

Folder IDs are configurable when you create or update a folder. For more information, refer to Understanding the folders list and Adding and updating folders.

This setting does not apply to folders' configured Point-to-point call incoming prefix registrations.

Gatekeeper status

The IP VCR also displays brief status information about its registrations with the configured gatekeeper.

 

Field Field description Usage tips
H.323 gatekeeper status

Displays the IP address of the gatekeeper currently being used by the IP VCR.

This information might be useful if the gatekeeper has been specified with a host name rather than with an IP address.

If the IP VCR has been unable to reach the configured gatekeeper and has instead registered with an alternate gatekeeper, the status displayed here is "registered with alternate gatekeeper <IP address>".

Registered address

Displays the local IP address and port number that the IP VCR has registered with the gatekeeper.

This information might be useful if the IP VCR has more than one IP address, for instance if both Ethernet interfaces are in use.

Alternate gatekeepers available

Displays the number of 'alternate' gatekeepers configured on the H.323 gatekeeper. This figure comes from the gatekeeper itself; if there are any 'alternate' gatekeepers configured, the gatekeeper tells the IP VCR their IP addresses.

Where the configured gatekeeper has told the IP VCR about any configured 'alternate' gatekeepers and if the IP VCR loses contact with the configured gatekeeper, the IP VCR will attempt to register with each of the 'alternates' in turn. If none of the 'alternate' gatekeepers responds, the IP VCR will report that the registration has failed.

If the IP VCR successfully registers with an 'alternate' gatekeeper:

  • the H.323 gatekeeper status will indicate that registration is with an 'alternate'
  • the list of 'alternates' received from the new gatekeeper will replace the previous list
  • the IP VCR will only revert back to the original gatekeeper if the 'alternate' fails and only if the original gatekeeper is configured as an 'alternate' on the current gatekeeper's list of 'alternates'

Note that if the IP VCR registers with an 'alternate' that does not itself supply a list of 'alternates', the IP VCR will retain the original list and if it loses contact with the current gatekeeper, each one will be attempted from the top again as before.

Number of active registrations

Displays the number of E.164 numbers plus H.323 IDs plus prefixes that the IP VCR has registered with the gatekeeper.

It also shows how many registrations are in progress but are not fully registered yet.

Full information on the gatekeeper registrations being made by the IP VCR can be seen by clicking details; this takes you to the Active registrations page.

H.323 ID registration

Displays the identifier that the IP VCR has used to register itself with the H.323 gatekeeper.

For more information about the H.323 ID, refer to the table above.

Prefix for IP VCR registrations

Displays the prefix registered with the gatekeeper for all registrations from the IP VCR.

For more information about this prefix, refer to the table above.

Play back prefix

Displays the prefix registered with the gatekeeper for playing back stored recordings.

For more information about this prefix, refer to the table above.


Active registrations page

Click details (next to the Number of active registrations status field) to go to the Active registrations page. This page shows the complete set of IDs that the IP VCR is attempting to register with the configured H.323 gatekeeper, and includes the H.323 ID, prefixes, and specific E.164 number registrations for recordings and folders.

Filters

You can configure filters so that only specific registrations are shown in the list. This may help you to find a registration whose number or name you know if the list is very long. The filtered registration list is automatically updated when you change the ID and name filters; to stop filtering the list either delete the filters or click Clear filters. If both the ID filter and the name filter are defined, the registration list will show only those entries which match both filters.

Registration list

The registration list shows, for each registered ID, the type of that ID (H.323 ID, prefix or E.164 number), the object it relates to, and the status of that registration. If you want to modify or remove a specific registered ID, click on the link in its Details column to be taken to the relevant configuration page.
