Highlights

MultiVOIP Applications. MultiVOIP is ideal for businesses looking to reduce toll charges between frequently called sites. MultiVOIP is a voice over IP gateway that integrates seamlessly into your data network and operates alongside an existing PBX to simply extend voice capabilities to remote locations. It is designed to help maximize investments already made in the data and voice network infrastructure.

SaveThousands of Dollars Each Month. MultiVOIP can save substantial amounts in long distance charges. Even if a company uses one of the most inexpensive calling plans, a MultiVOIP network can quickly return the investment and begin paying the company back.

Easy Integration. With MultiVOIP, you avoid the hassle and expense of replacing your existing routers, WAN connections or phone system required by other VOIP solutions. MultiVOIP simply plugs into your Ethernet network. Neither your phone service or network is placed at risk. Minimum requirements: Ethernet network, WAN connection, IP addresses.

Award-winning Voice Quality. With MultiVOIP, you’ll experience consistent toll-quality voice connections. Using the Perceptual Speech Quality Measurement (PSQM), Internet Telephony magazine found that MultiVOIP delivered exceptional voice quality. In fact, MultiVOIP outranked the competition.

Interoperability. MultiVOIP utilizes the H.323 and SIP protocols to provide complete interoperability with other Internet telephony solutions. The inbound IP call protocol is automatically detected and the voice channel is dynamically configured to match. The outbound IP call protocol is configured with the phone number, allowing you the flexibility to call H.323 or SIP devices from the same port.

Advanced Speech Technologies. MultiVOIP supports the Differentiated Services (DiffServ) Quality of Service (QoS) protocol which sets priorities for voice and fax traffic and allows transparent delivery. DiffServ helps move time-sensitive voice traffic across even low-bandwidth WAN connections, like 56K and ISDN, with the priority and quality required by voice. Other features such as adaptive echo cancellation, forward error correction, bad frame interpolation, tunable latency and dynamic jitter buffers, further enhance voice quality.

Bandwidth Management. Bandwidth is used only when someone is speaking. The silence suppression/Voice Activity Detection (VAD) feature is an option that frees unused call bandwidth for data traffic. This is significant, since callers are usually silent for 60 percent of the call. When using silence suppression, MultiVOIP also offers Comfort Noise Generation (CNG) at the receiving end so the user knows the line has not dropped. In addition, MultiVOIP supports voice compression standards like G.729 (8:1) and G.723 (10:1). These standards help minimize the bandwidth required for voice. G.723, for instance, is the maximum compression rate and requires only 5.3K bps (plus an added 7-8K bps for IP overhead). Even at maximum compression, your VOIP solution will still provide toll-quality voice.

No User Training. MultiVOIP provides single stage dialing by utilizing a Uniform Dialing Plan that is consistent with the E.164 (PSTN) standard numbering plan. This includes automatic appending and stripping of digits to dialed numbers to ensure that users will not require additional training to make VOIP calls. In fact, placing calls with MultiVOIP is like using your existing phone system.

Supplementary Services. MultiVOIP supports Q.SIG, an inter-PBX signaling protocol, for networking PBX supplementary services in a multi- or uni-vendor environment. And, with support for Dual Tone Multifrequency (DTMF), users can access their voice mail over the VOIP network.

Optional H.323 IP Telephony Gatekeeper. The MultiVOIP Gatekeeper is complementary product to the MultiVOIP Voice over IP gateway. The turnkey hardware and software solution provides corporate enterprise network managers and Intranet managers the power to define and control how H.323 voice traffic is managed over IP networks. With the MultiVOIP Gatekeeper, network managers have the ability to configure, monitor and manage the activity of registered network end points. In addition, managers can set policies and control network resources, such as bandwidth usage, to ensure optimal implementation.

You Be the Judge. Industry experts have recognized our VOIP gateways for their clarity. But don’t take their word for it, or ours. You be the judge! Make a FREE VOIP call over the Internet by dialing 1-877-TRYVOIP. Hear for yourself how clear the connection can be.
