Q&A
1.
Q: Can multiple PathNavigator servers share the same SQL server as the remote
database source?
A: No, each PathNavigator must have its own SQL server.
2.
Q: During the installation of PathNavigator, the Microsoft SQL server option is
chosen. What login ID and password should be used?
A: This should be the Microsoft SQL user login that has at least has the CREATE
DATABASE permission. Typically, the “sa” account has all the necessary
permissions to allow PathNavigator to create a “Gatekeeper” database in the SQL
server. To verify whether the login has the proper permission,
a.
On the SQL server, run the SQL Server Enterprise Manager and expand SQL
server tree.
b.
Under the Security folder, click on Logins, and see the list of logins at the
right side.
c.
Right mouse click on the username and select Properties.
d.
On the Server Roles tab, the System Administrators should be checked and
selected.
e.
Click on Properties button to view the permissions. The permissions list
should allow a CREATE DATABASE, DROP DATABASE, and ALTER DATABASE
commands to be executed.
3.
Q: What is the benefit of choosing Routed mode over Direct mode for the Call
Policy?
A: In routed mode, the call setup is routed through the PathNavigator using H.225
and H.245 call control protocol. Many of the unique features of PathNavigator
such as Simplified Dialing, Alternate Routing, Least Cost Routing, Hunt Groups,
Conference On Demand, and Call Forwarding are supported only in Routed mode.
Some features in Direct mode may not function optimally such as Firewall
Traversal.
4.
Q: What is considered a rogue call?
A: A rogue endpoint is defined as an unregistered endpoint for a given zone. When
an unregistered endpoint attempts to place a call to a registered endpoint within
the same zone or vice versa, (those networks defined in the Network Topology),
PathNavigator can deny this call or allow the call to go through. To capture
Rogue calls, the Call Policy must be set with “Log calls to/from unregistered
endpoints in this zone (rogues)” checked.
5.
Q: Does Conference on Demand work with other MCUs?
A: The Conference on Demand service in PathNavigator only works with the Polycom
MGC-100, MGC-50, or MGC 25. To use the service, the user has to specify the
administrative username and password of the MGC in PathNavigator.
6.
Q: Does an anti-virus program such as Norton
Antivirus interfere with
PathNavigator?
A: An anti-virus program can interfere with the PathNavigator application and the
SQL performance during the scanning process by means of over-burdening the
server CPU and disk access. If a comprehensive anti-virus scan runs on the
PathNavigator server, then its ability to log call registrations, resolve address for
incoming call, (to name just a few) will be severely degraded. This will likely
occur on a system that has marginal performance (CPU usage by Plcmgk.exe at a
