the dialer provide any support for giving promotions
to newly signed subscribers?
Yes it does!
We would like to give a small promo bonus to any
new subscribers so that they can test the service
before paying anything. The problem with such
promos is that they are misused thoroughly with
the same user signing up multiple times with different
logins. To combat this problem, GTPhoneDialer
sends the systems' network card's MAC address.
This is a unique ID for each system in the world
if it has a network card (most systems do). At
each signup, the dialer informs your web application
about this unique ID and the web application can
give bonus to first time users and decline to
other users if they are using the same machine.
To get the bonus again, the user will have to
replace her network card which isn't feasible.
To test this feature, visit our client http://www.gtphone.com

is licensing scheme for GTPhone Dialer?
licensing is based on "per active users".
An active user is one who has used the GTphone
dialer. It is free for user download now.
about licensing of the codec?
implementation of the dialer uses Microsoft's
G.723.1 codec. In the free price of the dialer
we do NOT cover licensing for the codec neither
do we ship any codec with our product. It is up
to you to get licensing for the codecs that you
use. The system can integrate most other implementations
The good news here is that we could not find anything
on Microsoft's website that requires any further
licensing fees for the use of their codecs. It
is our gut feeling that once a user gets the license
for Microsoft Windows, she is entitled to using
everything that comes with it so it is royalty
free by default. BUT our license agreement disclaims
any liability that may arise from Microsoft's
legal department later for the use of the codec.
In this regard you are totally on your own.
does your dialer use Microsoft's G.723.1 codec?
is shipping G.723.1 codec ever since Windows 95
times and it is there on all the client PCs running
any version of Windows. It has much better voice
quality than the ITU-Ts own implementation and
many other third party implementations of these
