What Is VoIP Or IP?

 

Xcelerator supports a standard unified dial plan, intercom calling and call forwarding across the network. Xcelerator IP offers built-in fax/modem tone detection. For music on hold (MOH), any .wav or .mp3 file converted into a .vox file can be uploaded to Xcelerator IP system via the Web-based Configuration Utility. Xcelerator IP does not support an external Music On Hold source.

Xcelerator IP supports up to three paging groups. In addition, ‘all call’ paging is also supported. In addition, Xcelerator IP supports External Paging by interfacing  a PSTN line to an external paging device. Xcelerator also supports up to a three party conferences. In the event of a power failure, Xcelerator IP will automatically switch the first PSTN line to the single line (FXS).

A user can configure and administer Xcelerator IP via the Web-based administrative interface, which is supported by the built-in Web Server, using either a wired or wireless connection. The Web-based  administrative interface is used to manage software upgrades to both Xcelerator IP and IP2007 phones. Back up is available. The user should save all configurations and voice prompts to a local PC or network server. This information can also be pushed to Xcelerator IP via an integrated TFTP server from the local PC or network server if they need restore the system.

Xcelerator IP supports DHCP so that PCs and the IP2007 phones are essentially “plug-and-play.” This means that when connected, PCs and IP2007 phones will automatically register with Xcelerator IP utilizing standard SIP protocols. To connect wireless devices, the user would select “Xcelerator IP” from the list of available wireless networks to register with Xcelerator IP. Xcelerator IP supports WEP, WPA and MAC address filtering to establish authentication and encryption for attached devices and prevent access by unauthorized users. Xcelerator IP can map a specific trunk to a specific IP2007 phone. In this manner, the calling party is mapped to that IP2007 when that trunk is dialed directly.

The IP2007 telephone supports an internal 400 entry directory per phone. The user can program the directory from the softkeys via the TUI or via the browser based administration GUI. Xcelerator IP features a built-in flash voicemail system. The voicemail system features 4 ports and supports up to 4 hours of flash-based memory for the entire system. Once the 4-hour limit is reached, the system begins to write over the oldest voice mail files. Up to twenty-four (24) voicemail boxes are supported. Each user can set up voicemail to send an email notification when a new voicemail message has been recorded. The voice message is attached to the email file as a .wav file. Users can record customized prompts for the main greeting, after hours greeting, lunchtime greeting, and holiday greeting. These recordings can either be recorded using a telephone, or recorded externally and pushed to Xcelerator IP as a vox file from the administration utility. Xcelerator IP supports two sets of voice prompts, making it easy to create voice prompts in two languages of your choice. Voice files are stored in the .vox format. Documentation is provided with each Xcelerator IP detailing the content and recording of all prompts on the system. When a message is left in a users mailbox, there is a voice mail icon on the left top corner of that person's LCD display. In addition, there is a Message Waiting indicator light on the top of the LCD.

IP2007 phones can access power from either a supplied  power adapter or via an external managed switch For PoE, the user simply  sets  an option switch on the back of the phone to the desired setting. The default setting is power adapter. When connecting more than four (4) IP2007 telephones to Xcelerator IP, a managed switch must be installed, which can be used to provide the PoE interface. A quality network switch/router with PoE (power over ethernet) is recommended. Telephones.com offers these switches as an option as well. A wall mount is included with the IP2007 phone, which will enable it to be mounted on the wall as well. Headsets are supported via a handset jack on the IP2007, as opposed to a 2.5mm jack.

Business Voice Mail and Messaging Service

A full-featured Flash-based voicemail system and auto attendant are fully integrated into Xcelerator™ IP – no additional cards or licenses are required. The system can serve up to 4 stations simultaneously and has a 4-hour recording capacity.

The flexible Auto Attendant voice messaging service time/date stamps all messages and provides the following options to incoming callers:

  • Dial a station number to reach someone
  • Leave a message in a particular mailbox
  • Play music on hold or announcements, such as hours of operation or driving directions.

The Auto Attendant provides the following features to users:

  • Play Day, Night, Lunch, Holiday and Temporary Greetings and messages
  • Send voice messages to e-mail inboxes as .WAV attachments
  • Forward incoming calls to other extensions
  • Play prompts in two languages
911 Support

Because Xcelerator IP supports both IP and analog (copper) trunking, it can support emergency 911 calls by provisioning a local copper line. Copper trunking is required to ensure that the Central Office is in the same Local Access and Transport Area (LATA) as the installed location. The analog line is not reserved for 911 support and can be used for regular calling as well as failover in the event of power failure. In the event of power failure, Xcelerator IP automatically falls back to the analog phone lines.

Fast Set Up

Xcelerator IP features a powerful yet easy-to-use Web-based setup wizard that walks the administrative user through each step required to configure the system. This application enables quick and easy access to the system to configure extensions, phone directories, numbering plans and auto attendant schedules from virtually anywhere. The system administrator can also back up messages, the system database and voice files to a PC.


COMPLETE SOLUTION IN ONE BOX

Xcelerator IP delivers a wide spectrum of voice and data handling capabilities. It is a data network, a phone system with advanced call handling features, a voicemail system, auto attendant, firewall, and wireless access point (WAP). One Xcelerator IP gateway supports up to 24 IP phones with robust calling features and true jitter and echo cancellation for high-quality voice reproduction. Xcelerator IP also supports additional networked office and business equipment such as computers, printers, card readers and fax machines.

Xcelerator IP also provides security with user authentication, password-protected system management, encryption, a built-in firewall, packet filtering and more. In the event of power failure, Xcelerator IP automatically falls back to PSTN.

Xcelerator IP provides everything you need at a fraction of the total cost of ownership to buy and support a solution built from separate components. Because of its all-in one architecture, you are assured that everything will inter-operate flawlessly right out-of-the-box

How does the Vertical Xcelerator work?

The Vertical Xcelerator IP, like most true IP (VoIP) Systems, requires CAT 5 or Cat 6 Network wiring. In most cases, it can share the wiring of your existing computer network system! IE, if you already have a networked computer in a location where a telephone is needed, you would simply connect the phone to that existing CAT 5 or CAT 6 computer wire and then connect the computer to the second IP connection under the phone. The Xcelerator Gateway and IP2007 Phones will configure themselves and also pass through the connection to the computer from the phones as well! If this sounds too easy to believe - BELIEVE us, ITS TRUE, AND ITS THAT EASY! If you require a true plug and play system that is FEATURE RICH and easy to install and program, then the Vertical Xcelerator IP System is for you!

Is an IP system right for me?

Even if you don't need an IP telephone system yet, Telephones.com still recommends going with an IP system. Most IP systems actually come out of the box as a conventional digital telephone system. You would install, program, and use it just like any other telephone system. Once you are ready to add go IP, you simply add the optional IP module and IP telephones. This keeps your initial costs down, and similar to a conventional telephone system.

Are you still using *TDM? Time-Division Multiplexing (TDM) is used in traditional digital phone systems. TDM could very well be reaching its expiry date, and the timeline for support for TDM is shrinking. It's inevitable. TDM is being quickly displaced with VoIP and IP Telephony.

Some IP Systems require the licensing of optional equipment and software. Larger, more advanced IP Systems like the Allworx, Samsung OfficeServ, and the Vertical SBX IP320 have optional advanced features and functions that may require the purchase of separate licenses and/or equipment in order to activate that particular product or feature. An example of this would be adding an off-site IP telephone in a different city or state connected to the main system that might require a site license. License costs and optional features vary from IP system to IP system, so please research them thoroughly. Smaller systems that DO NOT require licensing fees are the Vertical Xcelerator IP, Panasonic KX-HG400 IP, Avaya Quick Edition IP, and the Inter-Tel 3000 IP.

IP Phone Systems have features and optional equipment that are EXTREMLY advanced and unlike most features found on conventional analog, digital, or hybrid systems. IP Phone Systems are NOT harder to install than regular conventional systems, but they may require additional expertise when it comes to programming and configuring them. Besides the basic telephony knowledge required for phone systems, a complete understanding of LAN’s, WAN’s and Data Networking is also required for programming and configuring most IP Systems for off-site operations. The provided system manuals will fully explain this in technical terms, but depending on your knowledge on IP addressing, you may also require help from your local Network Administrator since the provided manuals will assume you already have a basic knowledge of computer networking fundamentals. An IP phone system will become PART of your computer network system (LAN), so if you understand your LAN's operations, you should have no trouble integrating the phone system to it. The rule of thumb here is that if you can configure a computer network system using IP addresses, MAC addresses, routers and switches, etc, then you should be able to set up an IP phone system as well. Most IP Systems tend to cost more than a conventional analog or digital phone system due to the more advanced features they contain. If you DO NOT have multiple offices that require integration or require off site locations for telecommuters, then most likely a regular analog or digital phone system will meet all your business needs and requirements.

Are there disadvantages to an IP phone system?

  • On the average, and IP phone system will cost you more. If you don't have multiple business locations that need to be networked together, a conventional analog, digital or hybrid phone system may be a better choice for you.
  • Most IP Phone System require CAT5/6 wiring. Its the same wiring used for your Computer network system. This may be advantages when adding a phone where a PC is already located because you can use the same wiring for both the IP phone and PC. If you don't have a networked PC at that location, then you will need to run Cat5/6 wiring to that location for the IP phone.
  • There is a myth that an IP system is not reliable. The fact is, an IP system is just as reliable, if not more reliable, than a conventional digital phone system. The MOST commonly reported problem with an IP system has to do with Quality-of-Service (QoS). The fact is, if you do not have the proper amount of bandwidth at all locations, then you will experience poor voice quality. The rule of thumb is simple. Maintain proper bandwidth for the amount of equipment is use and you will be extremely happy with the features and functions of an IP system. Period.
