Billing/Misc Tab

Chapter 7 - Using the MultiVOIP Software

The Fax group enables a fax machine to transmit and receive faxes through the MVP120. If a fax machine is connected to the via PBX port or PTSN, the Max Baud Rate should be set to match the baud rate of the fax machine (refer to user documentation). The Fax Volume setting controls the output level of the fax tones, and this setting should be changed only under the direction of Multi-Tech’s Technical Support personnel. The Jitter Value setting defines the inter- arrival packet deviation (in milliseconds) for the fax transmission. A higher value will increase the amount of delay (allowing for a higher percentage of packets to be reassembled) and a lower value would decrease the amount of delay (a lower percentage of packets would be reassembled).

The Advanced Features group allows you to enable Silence Compression so that a 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; Echo Cancellation for the voice channel will remove echo and improve the quality of sound; and, Forward Error Correction allowing 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.

This tab controls the parameters for auto call, automatic disconnection, billing options, and dynamic jitter buffer.

The Auto Call option allows the local MVP120 to call a remote MVP120 without the user having to dial a Phone Directory Database number. As soon as you access the local MVP120 voice/fax channel, the MVP120 immediately connects to the remote MVP120 that you identified in the Remote MVP120 Phone Number field of this option.

The Automatic Disconnection group provides three options which can be used singly or in any combination. The Jitter Value defines the average inter-arrival packet deviation (in milliseconds) before the call is automatically disconnected.The default is 20 milliseconds. A higher value means voice transmission will be more accepting of jitter. A lower value is less tolerant of jitter.

Consecutive Packets Lost defines the number of consecutive packets that are lost after which the call is automatically disconnected. The default is 30 packets.

Call Duration defines the maximum length of time (in seconds) that a call remains connected before the call is automatically disconnected. The default 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.

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.
