Problem
On one hand, GSM and National Telco operators provide
expensive long-distance rates to their users that do not allow these
users to make low cost long distance and international calls. On
the other hand, most GSM operators do not charge their users for
inbound calls but charge high rates for all outbound calls even
local calls. In countries that support government telecom monopoly,
users do not have any low cost options for making long-distance
calls because of the lack of call origination providers.
Solution
SysMaster Corporation offers call-back management
technology that allow GSM and telephone users to initiate long-distance
via SMS messages, Email messages, or ANI authentication. The call-back
technology allows inexpensive calls to be initiated by remote VoIP/Telco
gateways in both directions thus reducing call origination and termination
costs.
SMS Callback Service
The SMS Call-Back Service allows GSM users to initiate
long-distance calls by sending a SMS message to a special VoiceMaster
SMS Call-back Module equipped with a special GSM modem. The SMS
message contains user specific information such as PIN number and/or
authorized Phone number. Once the VoiceMaster server captures the
message, it triggers a call-back to the origination GSM phone or
to a specified in the user account phone number. Once the user picks
up the automated call he is presented with a dial tone to enter
the target destination number. The third-party gateway (VoIP/telco
switch) uses two call legs to connect the system user with the remote
party. VoiceMaster bills the users based on the rates set in the
VoiceMaster system and the duration of the calls.
E-mail Callback Service
The Email Call-Back Service allows phone users to
initiate long-distance calls by sending an email message using their
PC to a special VoiceMaster Email Call-back Module. The email message
contains user specific information such as PIN number and/or authorized
Phone number. Once the VoiceMaster server captures the message,
it triggers a call-back to the call-origination origination user
using the phone number in the user account. Once the user picks
up the automated call he is presented with a dial tone to enter
the target destination number. The third-party gateway (VoIP/telco
switch) uses two call legs to connect the system user with the remote
party. VoiceMaster bills the users based on the rates set in the
VoiceMaster system and the duration of the calls.
ANI Callback Service
The ANI Call-Back Service allows phone users to
initiate long-distance calls by calling the VoiceMaster ANI Call-back
Module equipped with a special modem that will recognized the caller
id. VoiceMaster will not pick up the initial cal but it will extract
the caller id automatically. Once the VoiceMaster server captures
the caller, it triggers a call-back to the call-origination origination
user using the phone number in the user account. Once the user picks
up the automated call he is presented with a dial tone to enter
the target destination number. The third-party gateway (VoIP/telco
switch) uses two call legs to connect the system user with the remote
party. VoiceMaster bills the users based on the rates set in the
VoiceMaster system and the duration of the calls.
