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.

Table 138 Troubleshooting Voice Service

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.
