Chapter 4 - Configuring the Master MultiVOIP

If you changed the voice coder, ensure that the same voice coder is used on the voice/ fax channel you are calling. Otherwise, you will always get a busy signal.

Note: If Automatic Coder is selected, then you need to select the Max Bandwidth from the list. Check with your Network Administrator to determine how much bandwidth is available.

19.The Fax group enables you to send/receive faxes on the selected voice/fax channel. You can set the maximum baud rate for faxes, the fax volume, and change the jitter value in milliseconds.

When receiving fax packets from a remote MVP120, 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 MVP120 uses a Jitter Buffer. The Jitter Value box allows the MVP120 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 given voice/fax channel, you can disable faxes in the Fax group.

20.You can enable the voice/fax advanced features by selecting the Silence Compression, Echo Cancellation, or Forward Error Correction options.

The Silence Compression option defines whether silence compression is enabled for the voice channel. If Silence Compression is enabled, the MVP120 will not transmit voice packets when silence is detected, thereby reducing the amount of network bandwidth that is being used by the voice channel.

If Echo Cancellation is enabled, the MVP120 will remove echo which improves the quality of sound.

The Forward Error Correction (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.

21.The Billing/Misc tab displays the parameters for auto call, automatic disconnection, billing options, and dynamic jitter buffer.

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 number), click the Auto Call Enable option in the Auto Call group. Then enter the phone number of the remote channel in the Phone Number box.

22.The Automatic Disconnection group provides three options to be used singly or in combination.

MVP120 specifications

Multi-Tech Systems MVP120 is an advanced communication device designed to enhance various applications across industries. It is a part of the Multi-Tech's MVP (MultiVoIP) product line, which is renowned for its versatility and robustness in VoIP (Voice over Internet Protocol) solutions. The MVP120 provides businesses with an efficient way to convert traditional analog voice signals into digital formats suitable for transmission over the Internet or other digital networks.

One of the main features of the MVP120 is its support for up to 12 voice channels. This capability allows multiple calls to be managed simultaneously, making it an ideal choice for businesses with high call volumes. The device offers a seamless integration with existing telephony systems, enabling users to retain their current infrastructure while benefiting from the added advantages of VoIP technology.

The MVP120 utilizes advanced Voice over IP protocols, including SIP (Session Initiation Protocol), which facilitates the establishment, management, and termination of voice sessions over the internet. SIP compatibility enhances interoperability with various service providers and existing communication systems, ensuring a flexible and scalable solution for businesses of all sizes.

Another noteworthy characteristic of the MVP120 is its built-in T.38 fax support. This enables the transmission of fax documents over IP networks, ensuring reliable delivery even in environments where traditional fax machines may experience disruptions. This feature is particularly beneficial for organizations that still rely on fax communication while transitioning to more modern digital systems.

Security is a primary concern in today’s digital environment, and the MVP120 addresses this with comprehensive protocol support, including SRTP (Secure Real-time Transport Protocol) and TLS (Transport Layer Security). These technologies ensure that voice communications remain secure and private, protecting sensitive information from potential threats.

The MVP120 is also designed with user-friendly management and configuration in mind. It features a web-based interface that makes it easy for administrators to set up and manage the device remotely. This simplifies the deployment process and minimizes downtime, allowing businesses to maintain operational continuity.

In essence, the Multi-Tech Systems MVP120 stands out as a powerful tool for businesses seeking to embrace the benefits of VoIP technology while maintaining reliable communication through traditional means. Its combination of voice channels, protocol support, fax capabilities, and security features make it an excellent choice for modern enterprises aiming to enhance their communication systems.
