Whether you receive voice service from legacy telephony providers or from Internet
Telephony Service Providers (ITSPs), Zultys delivers full phone system functionality. Users
gain access to the system from traditional handsets, mobile phones, desktop clients,
softphones and Instant Messaging. MX systems can be integrated into your business
environment through a number of methods, Telephony API (TAPI) being one of them.
The MX250 provides music on hold through an external connection
or from its internal hard drive. Overhead paging is supported using a SIP based
paging device, a FXS circuit or a 3 1/2 mm audio output. The system also provides
paging through the phones which can be separated into multiple zones.
The MX250 can be deployed as an independent standalone system or be connected to
other MX250 or MX30 systems by either a corporate network
or the open Internet.
G.729 voice compression is supported to reduce bandwidth requirement over a WAN.
The MX250 can be deployed as an adjunct to an existing legacy phone system or with the legacy
phone system configured as an adjunct to the MX250. Either configuration provides a smooth
migration path to SIP and SIP trunking with the realized benefits of cost, convenience
and productivity advantages.
The MX250 and MX30 include fax server functionality over any telephony interface.
Incoming faxes can be answered by the MX and converted to a graphical file which
can be sent via email to a user or retrieved using Zultys' unified communications
interface, MXIE (MX Interface for End-users). To send an outgoing fax, users print
to the MXIE fax printer from any available application. MXIE delivers the fax file
to the MX and updates the sender on the outcome of the transmission.
There are two 10/100Base-T ports available on the MX main board, accessible on the
rear panel of the system. One of these is connected to the client's LAN to provide
connectivity to devices such as PCs and IP phones. Both circuits may be connected
to separate Ethernet ports of two different data switches to provide redundancy
protection against customer-owned data equipment failure. In this configuration,
the switch-over relies on the spanning tree protocol of the MX250 to perform the
handover, and is automatic and requires no human intervention.
The MX250 and MX30 can function as an edge router and connect directly to an ISP
(Internet Service Provider). Default and static routes can be provisioned to control
the proper routing of voice and data traffic.
The system incorporates a firewall with NAT, for connection to the Internet. Also
DHCP, TFTP, and NTP servers provide services within the enterprise. Any of these
functions may optionally be disabled if they are provided external to the MX.
The MX250 and MX30 provide SIP application layer gateway (ALG) functionality when
the internal NAT and firewall functions are used. This allows users to make SIP
calls outside of the private address space used within the enterprise.
The MX250 provides VPN functionality for up to 50 users. This allows remote users
to securely access all functions of the MX250 and the corporate network. This function
resolves many issues that traveling personnel are likely to encounter when attempting
to connect via airport and hotel wired and wireless networks.
Connecting to a Phone
Zultys MX products provide multiple choices for supplying phone services to a user.
- Desktop: When deploying a standard SIP-based phone with a built-in switch, only
a single Ethernet cable run is required to the desk. The SIP phone is connected
directly to the local area network (LAN) through the first port of the built-in
data switch with the PC connected to the other port of the switch. If two Ethernet
circuits are already available at the desktop, one is connected to the phone and
the other to the PC.
- Softphone:The multimedia capabilities of the PC may be used by connecting a headset
to the appropriate jacks provided on the PC. In this case, the user may elect to
run a softphone application on the PC and forego the use of a physical phone. Such
an application allows station-to-station, external calls, and video calls to be
made or received easily at a minimal cost to the enterprise. This application is
also highly prized by remote workers and mobile users, regardless of their physical
location. All that is required is a connection to the Internet.
- Any phone: With MXconnect™ you can make ANY phone number (e.g.
your home or mobile phone) an extension of your office, allowing you to not only
answer your ringing extension from anywhere, but also place a call on hold or even
transfer the call back to an internal extension using our state-of-the-art MXIE™
CTI application. This new feature allows any phone with a direct access dial number
to be designated within MXIE as your primary device, extending your corporate office
environment to an analog or home office phone, a SIP phone, or even a mobile phone.
All incoming and outgoing calls will ring via that number, and since calls can be
initiated via MXIE this feature supports Least Cost Routing to save on your phone
bills. In conjunction with other MX system features, Zultys provides a complete
teleworker solution and allows anyone to work and connect from anywhere, including
your inbound Contact Center agents.
Peripherals and Deployment Accessories
BPS12 — Battery Power Supply
The BPS12 provides a reliable –48 VDC supply in a compact 19" 3U (5.25" high) chassis.
It can serve as the sole power source for various network elements in the enterprise
and provide uninterruptible power to those critical elements that need to remain
active when commercial AC power fails. Unlike traditional off-the-shelf AC uninterruptible
power supplies that are unreliable and complex to install, the BPS12 is an industrial
grade backup power supply intended for use with communications and networking equipment.
