Press Release Summary = Data Tech Labs is proud to release latest addition to its
product range, The Crossbow VoIP Exchange Engine. This intelligent platform allows
VoIP operators to increase their presence in global telephony market by establishing
Internet Telephony minutes trading system.

Crossbow Exchange works similar to any conventional stock or commodity trading
exchange with difference that its trading commodity is VoIP minutes. Like real world
exchanges, it supports offer posting and bidding, route quality calculation, real
time billing and routing.

Press Release Body = Principle of Operation

Crossbow Exchange Engine works like real stock exchange: sellers can post their
offers and buyers can place their bids. Both sellers and buyers are fully anonymous,
i.e., all traffic routing and payment settlement is done by You - Exchange owner.
Sellers can post their route ask prices based on particular route. Buyers can see
and choose routing based on price or quality criteria. Crossbow Engine makes routing
decision based on criteria selected by buyers and current route quality.

Offer

Crossbow Exchange engine is available as standalone software package. Radius-enabled
(including routing) switching platform is required to run this software. Currently
works with Mera MVTS Transit Softswitch. Other platforms soon to be added.

How It Works

Data Tech Labs Crossbow Exchange Engine is intelligent routing and rating platform
allowing service Providers to act as VoIP Traffic exchange Operators. It allows
Traffic Sellers to sell their routes and Traffic Buyers to view and buy routes
according to their desired quality and price requirements. It optimizes routing of
each call based on the buyers bidding criteria. Software comes with pre-populated
country and operator breakouts for almost 1,000 destinations, including some weekend
and off peak sensitive markets.

Destinations and Markets

Destinations and Markets are preloaded in Crossbow Exchange and are system-wide. It
makes uniform environment for all members participating in the Exchange: i.e. same
country codes and descriptions, same billing increments and same start and end times
of weekend and off-peak traffic. There are more than 900 destinations pre-loaded in
the Crossbow Exchange. The list is being currently updated from publicly available
sources. It supports grouping Destinations into groups, for example:
\"UK-Mobile-Vodafone\" and \"UK-Mobile-Orange\" are separate Destinations but also forms
Destination Group named \"UK-Mobile\". Therefore they can be traded both separately or
as a group. Some of Destinations may have time-sensitive trading, i.e. Peak,
Off-peak and Weekend trading. Crossbow Exchange Engine supports this function as
well. It is possible to define fixed start and end times of peak and off peak rates
based on specific time zone of Destination country.
There are two type of actions available to exchange members:
Selling, or Offer posting
Buying, or Bid posting
Each of the members can be simultaneously Seller or Buyer or both.

Sellers

Sellers post offers on the exchange and configure their equipment to receive traffic
from Exchange. They can post their offers to one of predefined markets and specify
asking price.

Buyers

Buyers should configure their equipment to send traffic to the exchange. They buy
traffic by placing bids. Two types of bids are available:
Price: A buyer places a bid for the maximum amount they are willing to pay for a
route. Calls are routed to the least expensive seller with an available route to the
bid amount;
Quality and Price: A buyer places a bid for the maximum amount they are willing to
pay for a route and the minimum quality they are willing to accept. Quality is
measured by multiplying the Answer Seizure Ratio (ASR) by the Average Call Duration
(ACD) to calculate the Score. Calls are routed to the seller with the highest Score
at or below the bid amount.

Exchange Fees

Exchange makes it profit from fees collected from buyers and sellers. Two types of
fees are available and configurable by operator:
Fee based on traded minute price. Various levels are supported. For example:
Destinations with offer price up to $0.05 - fee $0.002
Destinations with offer price between $0.05 and $0.10 - fee $0.003
Destinations with offer price between $0.10 and $0.50 - fee $0.0045
Destinations with offer price above $0.10 - fee $0.006
and so on ...
This fee can have billing increment different from that of particular destination.
For example, calls can be traded with 1/1 increments, whereas fees - at 60/60.
Fee based on percentage. Fixed percentage from sales amount;

Billing and Settlement

Billing cycle can be set at desired dates of month, for example bi-monthly; on 1st
and 16th of each month. It affects way how reports are presented, i.e. they are
bound to billing cycles. Buying Member is required to maintain positive balance in
order to make traffic purchases. Crossbow engine allows to refill balance at any
time buy making payments. Balance increases also when member has done some sales of
traffic. Balance settlements and payments are done exclusively through the exchange,
no peer to peer transactions are supported. At the end of each billing cycle system
sends out automatic period balance statement with opening balance, closing balance
and all activities during billing cycle. User can also make use of automated
notification system which informs about low balance (user selectable level) and
absence of funds in account.

Routing

Routing decisions are made in real time and new offers/bids are included into
routing immediately as they are activated. At each call attempt, Crossbow Exchange
tries to route call to all matched offers for particular bid, starting from most
appropriate. If match is found, call is connected. If none of offers match, call
will fail.

Route Quality Protection

Exchange administrator can select whether to activate Route Quality Protection
feature for particular Exchange member. when activated, this system will monitor
user\'s routes and if quality criteria is not met (Score
