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.
Complete Support for Multiple Telephony Interfaces. For maximum investment protection, the MultiVOIP two, four and eight-port models accommodate changing communication needs by providing an FXS, FXO and E&M interface for each port. With the right interface, the MultiVOIP connects directly to phones, fax machines, key phone systems or a PBX. With this range of support, you can connect a phone directly to a port today, and tomorrow connect your PBX trunk. A single port MultiVOIP supports either FXS or FXO interfaces depending on model while T1/E1 models connect directly to a PBX or PSTN line.
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.
Uniform Dialing Plan. MultiVOIP utilizes Multi-Tech’s Uniform Dialing Plan (MUDP). This allows for single stage dialing and ensures that users will not require additional training to make VOIP calls.
Management. MultiVOIP is easily managed locally or remotely by the central office with a web browser*, Windows 95/98/Me/2000, Windows NT software, tftp, Telnet or SNMP. Multi-Tech also includes its own SNMP management software called MultiVOIPManager which provides central site configuration, management and call monitoring for all MultiVOIP gateways on the network. It utilizes a Windows interface that makes it easy to view events like usage tracking, live use reporting, call history, and voice quality statistics. Call detail records may also be transferred to third-party billing software.
* Not available on digital models.
No User Training. Placing calls with the MultiVOIP is like using your existing phone system No end-user training is required. Users can begin making calls immediately with a published VOIP phone list and simple calling procedures.
Security. Your MultiVOIP network uses the same security as your data network. Therefore, if you have strong data security, your voice security will be strong as well. MultiVOIP also allows administrators to place it behind a compliant firewall to further enhance security. In addition, MultiVOIP provides interoperability with Virtual Private Network (VPN) products. And, when using MultiVOIP in proprietary mode, proprietary protocols make it difficult for hackers to access the VOIP network.
Access Voice Mail. Dual Tone Multifrequency (DTMF) support allows users to 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.
