1. If the Prefix for IP VCR registrations has been configured and the called number starts with that prefix, then the IP
VCR tries to match the rest of the called ID number (i.e. the part after the prefix) to a recording's Numeric ID or
to one of the folder IDs.
2. If a Play back prefix has been configured and it matches the called number, then the IP VCR tries to match the rest
of the called number (i.e. the part after the prefix) to a recording's Numeric ID.
3. The IP VCR tries to match the whole of the called number to a recording's Numeric ID or to one of the folder
IDs.
4. The IP VCR tries to match the called number against a folder's configured Point to point call incoming prefix. In the
event that more than one folder's Point to point call incoming prefix matches the called number, the IP VCR
chooses the folder which gives the longest prefix match
5. The call is treated as a call to just the IP VCR's IP address and the configured Default incoming call action is
followed.
Resulting action
If the above sequence results in a match against a recording's Numeric ID, then the recording is played back. If a folder's
Auto attendant ID is matched, then the endpoint is connected to the auto attendant menu for that folder. If the call matches
a folder's Recording ID or Recording console ID, the IP VCR starts a new recording in that folder (and starts up a recording
console, if appropriate).
Which IDs are registered with the gatekeeper Registering a recording's numeric ID
No individual registration will be made for a recording unless the H.323 gatekeeper checkbox in the Numeric ID registration
field is selected. In addition, if the recording is external (i.e. not stored on the IP VCR's own disk but accessed through a
link to an external NFS server) the folder's Register external recordings with gatekeeper setting must be selected as well as the
recording's own H.323 gatekeeper setting.
If the unit-wide Prefix for IP VCR registrations has not been configured, the IP VCR will register just the recording's Numeric
ID. However, if the Prefix for IP VCR registrations has been configured and use as prefix for registrations is selected, the IP VCR
will prepend that prefix to the recording's Numeric ID before registering it with the gatekeeper.
Registering a folder's auto attendant ID, recording ID, and recording console ID
No folder IDs will be registered with the gatekeeper unless the unit-wide Register folder IDs setting is selected. If it is
selected, then all configured Auto attendant IDs, Recording IDs and Recording console IDs for all folders will be registered with
the gatekeeper.
If the Prefix for IP VCR registrations has been configured and use as prefix for registrations selected for this field, then the IP
VCR will prepend that prefix to all folders IDs before registering them with the gatekeeper.
Registering a folder's point-to-point prefixes
In normal operation, whenever a folder has a configured Point to point call incoming prefix, that prefix will be registered
with the gatekeeper: there is no other unit-wide setting to enable or disable registration unlike the other folder IDs.
However, see Load balancing below.
