Multi-Tech Systems MVP120 manual Configuring the Slave MultiVOIPs

Chapter 5 - Configuring the Slave MultiVOIPs

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.

14.You can set billing options for inbound and/or outbound calls by selecting them in the Billing Options group and then entering the charge in cents per number of seconds.

15.A minimum and maximum set of values can be set for Dynamic Jitter Buffer. When receiving voice packets from a remote MVP120, 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 MVP120 uses a Dynamic Jitter Buffer. The Jitter Buffer allows the MVP120 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 MVP120 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.

16.To change the Tone Pairs on the Regional tab, select your country or region from the Country/Region list.

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

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

17.From the Main menu, click Phone Book to display the Phone Directory Database dialog box. Make certain the Proprietary Phonebook option is enabled and in the Database Type group, click the Slave option. The Master IP Address field becomes active.

Note: Refer to pages 28-30 if you had chosen Gatekeeper as the type of phone book database during the master phone book setup.
