The following PDF documents provide detailed explanations of the many facets of a Zultys system VOIP Installation:
MXIE - MX Interface for End Users
MXIE is the software client for the MX30, MX250, and MX1200 systems. Supported platforms are Windows 2000, Windows XP,
Mac OS X, and Linux. Features that enhance normal call handling include instant messaging, chat, presence, voice mail
access, call handling rules, and built-in softphone. An advanced version of MXIE allows the softphone to have
encryption, backup proxy, voice compression, and call conferencing.
MX30 - Enterprise Media Exchange
The MX30 is a powerful system that enables multimedia communications for all
workers in a small office. By integrating the functions of many devices into a
compact box, the MX30 simplifies the VoIP network of any deployment. As well as
being a comprehensive solution, the MX30 is easy to install, use, and maintain.
A single slot on the rear side of the chassis is available to accommodate one of
the following PSTN interface cards:
-
2 analog FXO circuits (for connection to the PSTN)
-
4 analog FXO circuits (for connection to the PSTN)
-
1 ISDN BRA circuit (for connection to the PSTN with S/T interface)
-
2 ISDN BRA circuits (for connection to the PSTN with S/T interface)
MX250 - Enterprise Media Exchange
The MX250 is a truly converged product that makes VoIP affordable for small
to medium businesses or branch offices. This single 2U box (3.5" high) scales
from 5 to 250 users without additional hardware. It combines the functionality
of a PBX, voice mail server, voice gateway, and internet gateway. Built with the
same technology and the same productivity tools as the MX1200, the MX250
provides smaller sites with all premium features at attractive prices. Cluster
configuration allows the system to grow to 1000 users per site. Three slots on
the rear side of the chassis are available to
accommodate a combination of the following PSTN interface cards:
-
8 analog FXO circuits (for connection to the PSTN)
-
8 analog FXS circuits (for connection to analog phones)
-
4 ISDN BRA circuit (for connection to the PSTN with S/T interface)
-
2 T1 or E1 circuits (for connection to the PSTN, gateway, or tie line of a PBX)
MX1200 - Enterprise Media Exchange
The MX1200 is the highest density phone system available. This single 2U box
(3.5" high) brings together the functionality of a PBX, voice mail server,
switch router, and internet gateway. With a host of productivity applications,
such as instant messaging, presence, and voice mail management on the PC, the
MX1200 can streamline communications for facilities with 25 to 1200 users.
Companies can easily deploy and manage the MX1200 within new or existing
networks because the system is based on open standards, embedding technologies
such as SIP, TAPI, VoiceXML, and Linux. You can connect up to 7 T1 circuits to
the PSTN, and there are a total of 28 Ethernet ports, 12 of which provide Power
over Ethernet, on the rear side of the chassis.
Fax - Direct Origination and Termination
The fax option on the MX system provides origination and termination of real
time fax sessions directly on the MX30 or MX250. This eliminates the requirement
for external fax machines or servers. You can configure the MX30 to handle up to
4 fax sessions and the MX250 to handle up to 16 fax sessions. Fax resources can
be shared among all users, so you can configure a fax DID separate from the
voice DID for each user.
ALG (Application Layer Gateway) - Connectivity to public SIP gateways
The MX30 and MX250 can connect to Internet Telephony Service Providers
(ITSPs) for public SIP access to phone service. ITSPs can provide IP trunking
for all business calls, eliminating the need for direct connectivity to the
PSTN. At the SIP layer (application layer), ALG services translate the public IP
address with private corporate addressing to allow phone calls between private
IP phones within the corporate firewall and public SIP gateways. With ALG
services on the MX250, a business can connect up to 50 simultaneous trunk calls
through ITSPs. The MX30 can connect up to 10.
Redundancy - Automatic Redundancy Option for MX250
The Redundancy option on the MX250 provides automatic recovery during a
hardware failure. The redundancy configuration uses an N+1 scheme where N can be
one, two, or four MX250 boxes that service users during normal operation within
a single deployment. The extra MX250 serves as a warm standby, which contains a
mirror image of the configuration of the MX250 systems that run in normal
operation. When an MX250 fails during normal operation, the standby MX250
automatically takes over from the failed unit with only a few minutes of down
time. The redundancy option requires the additional purchase of the standby
MX250 and an XRS12 chassis to switch the PSTN circuits. When the redundancy
option is installed on the primary MX250, all licenses will automatically
transfer to the standby MX250 during failover operation.
Inbound Call Center - Features for the Call Center
The Inbound Call Center (Advanced ACD) option for the MX30 and MX250
provides features that help to streamline call handling for companies that have
dedicated call centers. A group can be provisioned with 64 agents on the MX250
and 30 agents on the MX30. Features include call queueing, real time supervisory
monitoring, detailed reports for agent and group performance, automatic logging
out of unresponsive agents, music on hold, promotional messages while on hold.
call quit options, queue prioritization, instant messaging between agents and
supervisors, and queue overflow handling. VPN, Termination on MX250 The MX30 and
MX250 has internal capabilities for terminating VPN (IPsec) tunnels from
external VPN gateways such as home routers or IP phones. This ability is ideal
for corporate deployments of the MX system where there is no external VPN
concentrator to terminate remote users. With VPN tunneling directly into the MX
system, business can quickly extend voice and collaboration services to remote
workers while providing them a secure data access to corporate network servers.
MXgroup - MX Group Option
The MXgroup software license for an MX30 or MX250 allows it to be part of a
group of MX30 or MX250 systems. This permits the extension of most features of
an MX250 across multiple locations and therefore makes a company spread among
multiple locations appear as one. Users at any one location can communicate with
users at other locations in the same way that they communicate with users at the
same location. You can configure a single group to include MX systems or
MXclusters from 2 to 32 locations, which allows an enterprise to scale its
deployment to 10,000 users. The MX30 and MX250 systems communicate over a WAN or
the Internet and are easily configured. No intervention is required by the users
of the systems.
Firewall and NAT
Firewall and NAT functions can be enabled on the MX30 and MX250. This is
ideal for businesses who do not have an external firewall and NAT in their
corporate network. The MX firewall is a layer 3 and layer 4 device, with
stateful inspection of the packets and an average throughput of 2 Mb/s.
G.729 Voice Compression
The MX30 and MX250 systems can provide termination for G.729 voice
compression. Voice compression minimises bandwidth requirements for calls over
WAN or Internet links where capacity is often limited. The MX30 can terminate 10
channels of G.729, while the MX250 can terminate G.729 on 50 channels.
Call Recording on Demand
The MX30 and MX250 can store call recordings initiated by users. Each user
controls the call recording from MXIE. They are able to start, pause, and stop each
recording at any time during a phone conversation. This option is licensed by
concurrent channel of recording.
