31 Configuring the MultiVOIP Address (202.056.039.100), and accept the H.323 industry standard Port value (1720) used to communicate with other H.323 endpoints. 37. Click OK and you are returned to the Phone Directory Database dialog box which now includes the remote phone number and related information in the Phone Number list.
MultiVOIP Quick Start Guide 32 38. To configure a stand-alone endpoint (for example, a PC with NetMeeting software), click Add and the Add/Edit Phone Entry dialog box displays again. 39. Enter the phone number for the stand-alone endpoint in the Station Information group Phone Number box. For example, 301. 40. Click inside the Description box and enter a description for the remote NetMeeting. For example, “Human Resources Desk”. Note: Because the H.323 endpoint is not a MVP110, the Phone Directory database ignores the Voice Channel entry. It does not matter what value is entered. 41. In the Station Identification group, select NO HUNT from the Hunt Group list, enter the Human Resource Desk’s IP Address (202.198.100.04), and accept the H.323 industry standard Port value (1720) used to communicate with other H.323 endpoints. Note: This stand-alone was not configured as part of a

Click OK and you are returned to the Phone Directory Database dialog box which now includes the stand-alone phone number and related information in the Phone Number list.
MultiVOIP Quick Start Guide 3443. When you have finished, click OK to download the default setup. 44. Click OK. After the setup is written to the MVP110, the unit reboots. 45. Check to ensure that the BOOT LED on the MVP110 is off after the download is complete. This may take several minutes as the MVP110 reboots. At this time your master MVP110 is configured. Proceed to the “Configuring Your Slave MVP110s” section. Configuring Your Slave MVP110s If the Proprietary Phonebook option on the Phone Directory Database dialog box was enabled, then you will need to configure all remote H.323 endpoints as “Slave” units. For example, the MVP110 at the company’s subsidiary office in London would need to be configured as a “Slave”. CAUTION: If you are installing a MVP110 behind a Firewall, the Firewall must support H.323. Refer to your Firewall user documentation to enable H.323 support. 1. Disconnect the PC from the Command port of the Master MVP110 and connect it to the Command port on the Slave MVP110.
35 Configuring MultiVOIP Slaves 2. From your desktop, click Programs I MultiVOIP 100 I MultiVOIP 100 Configuration. The Main menu displays. 3. Click IP to display the IP Setup dialog box. Select the Enable Diffserv check box if you have routers
MultiVOIP Quick Start Guide 36that support Diffserv (sometimes called IP Precedence). This feature gives priority to voice packets so they are not delayed because of large data files being downloaded. The default Frame Type is TYPE_II. If this does not match your IP network, select the Frame Type from the Frame Type list. The Frame Type choices are TYPE_II and SNAP. 4. In the Port Address group, enter the IP Address and IP Mask. In the Gateway Address group, enter the gateway IP address for the slave unit. The IP Address is the unique IP address that you assign to the MVP110, and the Gateway Address is the IP address of the device (such as a network router) connected to the Internet/Intranet. Click OK when you are finished. The Main menu displays. 5. From the Main menu, click Voice Channel to display the Channel Setup dialog box. The Channel Setup dialog box displays. The four tabs in this dialog box define the channel interface, voice/fax parameters, Billing/Misc parameters, and regional telephone parameters for the channel.
37 Configuring MultiVOIP Slaves Feature options are enabled or disabled according to the interface type. The Inter Digit Time option defines the maximum amount of time that the unit will wait before mapping the dialed digits to an entry in the Phone Directory Database. If too much time elapses between digits, and the wrong numbers are mapped, you will hear a rapid busy signal. If this happens, it will be necessary to hang up and dial again. The default is 2 seconds. 6. The Ring Count FXS window allows you to set the maximum number of rings output on the FXS interface before hanging up and releasing the line to another call. The default setting is 8 counts. Note: Zero (0) means no rings - caller hears a busy tone. 7. The Voice/Fax tab displays the parameters for the voice gain, DTMF (Dual Tone Multi-Frequency) gain, voice coder, faxing, and advanced features such as Silence Compression, Echo Cancellation, and Forward Error Correction.
MultiVOIP Quick Start Guide 38 8. Input gain modifies the level of the audio coming in to the voice channel before it is sent over the Internet to the remote MultiVOIP. Output gain modifies the level of the audio being output to the device attached to the voice channel. Make your selections from the Input and Output lists in the Voice Gain group. The valid range is +31dB to –31dB with a recommended/default value of 0. You can also set up the DTMF gain (or output level in decibels - dB) for the higher and lower frequency groups of the DTMF tone pair. Make your selections in the drop- down lists in the DTMF Gain group. Note: Only change the DTMF gain under the direction of Multi-Tech Technical Support supervision. 9. To change the voice coder, select the Manual option in the Coder group. Select the appropriate coder from the Selected Coder list. If you changed the voice coder, ensure that the same voice coder is used on the voice/fax channel you are
39 Configuring MultiVOIP Slaves calling; otherwise, you will always get a busy signal. Note: If the Coder is selected automatically, enter the bandwidth in the Max Bandwidth from the list. Check with your VOIP administrator to determine how much bandwidth is available. 10. The Fax group enables you to send/receive faxes. You can set the maximum baud rate for faxes and the fax volume in the two lists and change the jitter value in milliseconds. When receiving fax packets from a remote MultiVOIP, it is possible for individual packets to be delayed or received out of order due to traffic conditions on the network. To compensate for this effect, the MVP 110 uses a Jitter Buffer. The Jitter Value box allows the MVP 110 to wait a user-definable period of time, in milliseconds, for delayed or out of order fax packets. The range of allowable Jitter Values is 0 to 400 with a default of 400 milliseconds. If you do not plan to send or receive faxes on a voice/fax channel, you can disable faxes in the Fax group. 11. You can enable the voice/fax advanced features by clicking (checking) the silence compression, echo cancellation, or forward error correction options. The Silence Compression option defines whether silence compression is selected. If silence compression is enabled, the MVP110 will not transmit voice packets when silence is detected, thereby reducing the amount of network bandwidth that is being used by the voice channel. The Echo Cancellation option defines whether echo cancellation is enabled for the Voice/Fax Channel. If echo cancellation is enabled, the MVP110 will remove echo- delay which improves the quality of sound.
MultiVOIP Quick Start Guide 40The Forward Error Correction (FEC) option defines whether forward error correction is enabled for the voice channel. The FEC feature allows some of the voice packets that were corrupted or lost to be recovered. FEC adds an additional 50% overhead to the total network bandwidth consumed by the voice channel. The Billing/Misc tab displays the parameters for auto call, automatic disconnection, billing options and dynamic jitter buffer. 12. If you want to dedicate a local voice/fax channel to a remote voice/fax channel (so you will not have to dial the remote channel), click the Auto Call Enable option in the Auto Call group. Then enter the phone number of the remote MultiVOIP in the Phone Number box. 13. The Automatic Disconnection group provides three options to be used singly or in combination. The Jitter Value defines the average inter-arrival packet deviation (in milliseconds) before the call is automatically
