The VTX is a powerful system that simplifies voice communications for all workers in a small to medium size office, multiple remote locations, home workers, and workers who are on the road. The VTX is easy to install, use, and maintain. The embedded system design on the VTX makes it the most stable system in the industry.
The VTX comes with four modular slots; each can be used with an 8 port FXS card, an 8 port FXO card, or a 2 port T1/E1 card. This ensures the VTX can be fully connected to the PSTN.
The VTX is also designed to connect to Internet telephony service providers (ITSPs) using SIP. Customers will save money on making phone calls because of the low rates offered by ITSPs. Customers will also save money on infrastructure because the VTX can be easily integrated into their existing networks.
The system combines the functions of an IP PBX, Internet gateway, PSTN gateway, network server, and application server. By using standard protocols, it is interoperable with phones, gateways, and devices from other manufacturers.
The VTX can interoperate with any SIP compliant phone. VoIPTREX has its own range of IP phones that is fully compatible with the VTX. These include desktop phones as well as a soft phone.
In addition to the soft phone that runs on a PC, VoIPTREX provides a soft phone client that runs on any Windows based PDA.
The VTX can connect to up to eight ITSPs (Internet telephony service providers). This permits the use of the Internet for all voice calls without the need to connect to the PSTN. Alternatively, the VTX can connect to the PSTN through its modular cards: FXO and T1/E1.
VoIPTREX sells and supports its products worldwide, allowing the VTX to be readily deployed in one or more countries. The system supports telephony protocols for many countries so it can connect directly to the local PSTN. You can navigate the VTX’s administration UI in two different languages: English and Simplified Chinese.
The VTX has four modular slots that allow you to install the modular cards you need. You can install an 8 port FXS card for analog phones or fax machines, 8 port FXO card for traditional phone lines, or a 2 port T1/E1 card for digital lines. The FXS interfaces can be provisioned as extensions in normal use or assigned a DID number.
Additionally, you can also install a 4FXO/4FXS combo card with bypass on the VTX. These circuits provide lifeline support in case of total power failure.
The VTX has an HTML based administration UI so that it is not necessary to install any management software on a PC. The administration UI is intuitive and easy to navigate. Customers may access and manage the VTX from anywhere as long as they have access to the Internet. The administration UI provides various real time information and statistics of the VTX. These include operation state, system and network information, events and alarms, active phones, active calls, IP Trunks status, and more.
Adding, modifying and deleting a user can be done in a matter of few clicks. Customers can assign different rights and privileges to different users. These rights include Operator, Voicemail, Call Restrictions, and Trunks.
The VTX has an HTML based user portal. Users can log on to the system using any web browser to download, save, and delete their voice messages, change their mail box password, and configure their personal call handling rules.
The system has a flexible dial plan that allows you to specify the routing of calls based on dialled patterns. Your organization can ensure least cost routing for all calls, regardless of the user or location.
For each dial pattern on the dial plan, you specify the transformed pattern, the primary route, and alternative routes. You can create multiple dial patterns to handle internal calls and external calls. These calls can be routed over the LAN, the WAN, the Internet at an external gateway, or a line interface to the PSTN.
You can restrict calls to specific destinations per user. This allows you to specify who has the rights to make long distance and international calls.
The VTX can play MoH to callers. This is played from a WAV file on the internal flash memory disc.
The VTX allows users to be reached even when they are home or travelling. Users can have multiple contact points where they can receive calls. A contact point can be an IP desktop phone or soft phone. An incoming call will alert all contact points simultaneously. Users can also create custom call handling rules that can forward their calls to external numbers based on different conditions.
The VTX makes it uncomplicated to connect remote phones. Most VoIP solutions today require remote users to use a VPN or other tunneling technologies. With the VTX, remote users can connect with the system, even when they are behind a NAT, router, or firewall, without the need to use a VPN.
Remote extensions can be achieved easily by setting up call handling rules that route all the calls to a user’s home or mobile phone numbers.
Incoming calls can be routed to an automated attendant (AA), a live attendant, or an operator. The AA or operator can be assigned a direct external number (DID) and an internal extension number. The VTX allows you to specify working hours and greeting messages that are played during working hours and nonworking hours. The AA provides the features of dial by name, scheduled greeting messages, and transferring incoming call to different extensions. It is extremely easy to setup and modify.
The VTX can provide multiple hunt groups for an informal call center. You can configure hunt groups for different services within the business. Each group can be assigned a direct inward dial number (DID) in addition to an internal extension. You can assign a user to be an agent for one or more groups, and agents within a group can still make and receive individual calls.
The VTX provides a conference bridge supports up to five participants in a conference session. Each participant can join or leave the conference at any time. The conference can be put on hold, allowing the other parties to continue without the host.
VoIPTREX provides ACD (Automatic Call Distribution) for basic call center needs. You can configure multiple ACD groups on the VTX, each for a different service within the organization. Each agent in a group can be assigned a skill level for a more efficient call distribution. Other call distribution strategies, such as ring all and round robin are also available. Each ACD group can be assigned one or multiple DID numbers in addition to the internal extension.
Users can access, save, and delete VM by using a phone (internal or external to the VTX) or by using the Personal Portal. Users can save their voice messages without taking up storage on the VTX by saving the messages into folders on the local PC. Voice messages are saved as files and can be forwarded to others outside the system through standard means of file sharing such as e-mail and network directories.
The VTX has a compact flash port that allows customers to install a compact flash drive for voice mail storage. A 2 GB compact flash drive will store up to about 2000 minutes of voice messages for the whole system.
The VTX supports fax to devices connected to the analog FXS ports. This can be with fax pass through or with T.38 fax which is supported by most ITSPs.
The VTX has two Ethernet ports – one connects to the service provider and one connects inside the office.
The WAN port connects directly behind the broadband IAD (integrated access device) and provides termination of traffic and address translation. The translation comprises NAT (network address translation) for Internet traffic and ALG (application layer gateway) for SIP traffic. The VTX accomplishes much more than simple ALG by allowing flexible selection of how direct media is handled to ensure simple integration in a variety of network configurations.
The WAN port can have a fixed IP address, an IP address received from the ISP using DHCP, or use PPPoE to obtain all information. Default and static routes can be provisioned to control the proper routing of voice and data traffic.
The LAN port connects directly to devices or an Ethernet switch. Over this port, the VTX can provide DHCP service.
Most IP networks existing today support VLAN and QoS. Having VLAN and QoS can increase the voice quality of phone calls. The VTX fully supports IEEE 802.1q VLAN tagging and IEEE 802.1p QoS. At the IP layer, the VTX support the ability to mark the lower six bits of the IP QoS byte with the various differentiated service code point (DSCP) markings.
The VTX provides comprehensive CDR for reconciliation of billing and tracking of system usage. The VTX supports RADIUS client, which can be used to interact with a RADIUS server for authentication. Using this feature, you can easily integrate the VTX with any billing system that support RADIUS.
The VTX provides Ping, Traceroute, and DNS Lookup for network diagnostic. These tools will help you identify most networking problems. To identify call setup problems, the VTX also provides SIP Route Trace diagnostic tool. The VTX supports SNMP. This powerful feature allows you to make various queries and traps to the VTX using the SNMP.
