Chapter 3 - Software Loading and Configuration

Call Duration defines the maximum length of time (in seconds) that a call remains connected

before the call is automatically disconnected. The default setting is 180 seconds. A call limit of

three minutes may be too short for most configurations. Therefore, you may want to increase this

default value.

23. You can set billing options for inbound and/or outbound calls by checking them in the Billing

Options group and then entering the charge in cents per number of seconds.

24. A minimum and maximum set of values can be set for Dynamic Jitter Buffer. When receiving

voice packets from a remote MultiVOIP 400/800, it is possible to experience varying delays

between packets due to traffic conditions on the network. This is called Jitter. To compensate for

this effect, the MultiVOIP 400/800 uses a Dynamic Jitter Buffer. The Jitter Buffer allows the

MultiVOIP 400/800 to wait for delayed voice packets by automatically adjusting the length of the

Jitter Buffer between configurable minimum and maximum values. An Optimization Factor

adjustment controls how quickly the length of the Jitter Buffer is increased when jitter increases

on the network. The length of the jitter buffer directly effects the voice delay between MultiVOIP

400/800 gateways.

The Minimum Jitter Value default setting is 150 milliseconds, the Maximum Jitter Value default

setting is 300 milliseconds, and the Optimization Factor default setting is 7.

Note: After configuring a given channel, you can copy that channel’s configuration to the other

channel by clicking the Copy button. Everything on the Billing/Misc tab will be copied to the

designated channel.

If your country/region is not the default USA, click the Regional tab and proceed to step 25;

otherwise, proceed to step 26 to begin building your phone directory database.

25. To change the Tone Pairs on the Regional tab, click the Country/Region down arrow and

highlight your specific country or region.

Note: If your country or region is not listed, click the Custom button to define it.

The Tone Pairs group enables you to select/modify the parameters according to choice. Click

OK when finished. Proceed to step 26 to begin building your phone directory database.

26. The Phone Directory Database dialog box is displayed. This dialog box enables you to add,

delete, edit phone entries, or print all entries currently in the Phone Directory Database, and view

the telephone numbers defined in each Hunt group. You can build a proprietary phonebook (Go

to step 27); or, if an H.323 Gatekeeper is available and enabled, you can register your phone

numbers with the Gatekeeper (Go to the following section “Registering with a Gatekeeper Phone

Directory”).
