37.8 Problems with Voice Service
37.9 Pop-up Windows, JavaScripts and Java Permissions
In order to use the web configurator you need to allow:
• Web browser pop-up windows from your device.
• JavaScripts (enabled by default).
• Java permissions (enabled by default).
Note: Internet Explorer 6 screens are used here. Screens for other Internet Explorer
versions may vary.
37.9.1 Internet Explorer Pop-up Blockers
You may have to disable pop-up blocking to log into your device.
Either disable pop-up blocking (enabled by default in Windows XP SP (Service Pack) 2) or
allow pop-up blocking and create an exception for your device’s IP address.
37.9.1.1 Disable Pop-up Blockers
1 In Internet Explorer, select Tools, Pop-up Blocker and then select Turn Off Pop-up
Blocker.

PROBLEM CORRECTIVE ACTION
After VoIP is
configured and
working, others are
unable to call you
or you lose your
connection during a
call. There is a NAT
router between the
Prestige and the
SIP server.
This could be caused by a short NAT UDP session timeout on the NAT router.
When the SIP session’s entry in the NAT table times out, the NAT router does not
have any record to use for forwarding VoIP traffic to the Prestige.
If possible, set the NAT router to use a longer NAT UDP session timeout.
Otherwise, try one of the following:
• Shorten the registration expiration period (see the Expiration Duration field
in the VoIP Advanced screen) in order to cause the Prestige to re-register
with the SIP register server more frequently. Note that this will not help if the
SIP register server enforces a long registration expiration period (since the
Prestige will also use the period set by the SIP register server).
• Use STUN. If your VoIP service provider does not have a STUN server, you
can still enable STUN and enter the IP address and port number of the SIP
server in the STUN server fields. This causes the Prestige to send STUN
requests to the SIP server. While this will not make STUN work (since there
won’t be any responses to the STUN requests), it should keep the NAT UDP
session in the NAT router.
