Multi-Tech Systems has introduced its new MultiVOIP voice and fax over IP gateways targeted towards businesses implementing SIP telephony. The new VoIP gateways are available in two-, four-, and eight-port models, and include features selected specifically for implementing SIP telephony. They are cost-effectively priced, while still offering business-class quality and performance.
The MultiVOIP FX gateways connect to analog ports using two, four, or eight FXS or FXO interfaces. They connect to an IP network using a 10/100BaseT interface, include an RS232 command port, can be controlled through a Web browser, and are flash upgradeable. These new models support SIP for sending and receiving voice over an IP network, T.38 real-time fax relaying for VoIP equipment interoperability, Voice Activity Detection for silence compression, Comfort Noise Generation for a more natural speaking experience, and they utilize 5.3K bps voice compression for maximizing bandwidth.
The SIP standard, primarily developed by IETF SIP working group, allows for the interoperability of a large number of devices from various vendors with those devices being easily configured and automatically updated as necessary. The new MultiVOIP FX gateways enable the integration of existing telephony equipment into SIP networks. SIP-based telephony networks offer stable interoperability with a wide range of features and flexibility. The new Multi-Tech Systems MultiVOIP FX products fit well into such networks by being able to adapt existing telephony equipment to evolving user requirements. http://www.multitech.com
