switching settings in comprehensive manner.

» Real-time monitoring, live calls information, statistics at a glance ( number of
connections, connected calls, registered users, ASR/ACD/ PDD and others).
» Registered users details, gatekeepers/sip registrars status, system logs.» Debug functionality for selected connections.
Callback module allows for implementation of various types of callback based services. What is
common for all of them is that it is the system (VoipSwitch) that initiates connections to two end
points on a user request. The types of callback differ in the way ofhow a user can trigger the
service and also they are often divided depending on how the user’s requests are authorized:
REGULAR CALLBACK : Initiated by making a phone call to a provider’s service number. The service
number can be implemented by the mean of DID from DIDs provider, PSTN orGSM gateway or a mobile
phone connected to a PC (not necessarily server) with a special application (which is part of the
module) that communicates with the mobile and forwards requests to VoipSwitch
AUTHORIZATION METHODS:
»
By PIN the system calls back to the caller ID that has come with the call, after the call
is connected the IVR prompts for a PIN, after successful authorization the two stage
dialing scenario is processed.
»
By Caller ID (ANI) the system tries to authorize the Caller ID received with the
triggering call, if authorization is successful (the caller ID is associated with a user
account in the system), the system makes a call to the caller ID or to a default phone
number assigned to the user account (defined by the user e.g. from the web)
»
By DID in this method each user has a unique DID (virtual phone number) associated
with his/her account. After dialing this DID the system initiates a call to a predefined
phone number associated with the account (not the caller ID). This service is mainly for
users that for requesting callback use phone services with blocked caller ID
SMS CALLBACK :
In this method users trigger the callback by sending SMS to a provider’s service number.
The service number can be implemented by the mean of a mobile phone connected to a PC (not
necessarily server) with a special application (which is part of the module) that communicates with the
mobile and forwards requests to VoipSwitch. Another method isrenting the SMS number from SMS
provider which will forward incoming text messages to specified VoipSwitch URL.
Authorization in this method can be by Caller ID of the phone from which SMS has been send or by
user/password (or PIN) send in SMS content.
WEB CALLBACK :
This service is sometimes called Connect Two and is a conference between two parties initiated from
the web interface level or from a special, desktop application i.e. Callback Dialer.
IP IVR Calling card module:
EXAMPLES OF ADDITIONAL IP IVR SCENARIOUS:
» Max call duration announcement.
» Actual balance information
» Last minute (or any other defined period) before the call end warning.
» Recharge by PIN
» Support number and others.
The IP IVR module extends VoipSwitch of the whole set of services that utilizes voice interaction with
users. The IP IVR version for Calling cards services is sold separately as a module. The IP IVR for
other services is the part of the main package (VoipSwitch platform).
The IP IVR can be used with any VoIP equipment that is compatible with SIP or H323 protocol. Also
it supports DIDs (SIP or H323 trunks). Thus, the access number for example for Calling cards can be
implemented by using DIDs rented from a provider (instead of owning a PSTN gateway). In this
scenario DID or DIDs are delivered over Internet directly from DID provider to VoipSwitch.
The IP IVR supports following Codecs: G723.1, G729, G711, GSM, G722. The voice prompts are stored
in already compressed format what makes the system robust as it does not have to convert the prompts
while realizing the IVR procedures.
The IVR scenarios as well as voice prompts are customizable. It comes with predefined scenarios
that can be found useful in different applications. Also the new scenarios can be built by system
administrator using XML scripting language.
The system is multilingual by default there are several languages uploaded, for exampleEnglish,
French, Spanish, Arabic, Hebrew and many others.
RESELLERS :
Reseller’s module is an additional module that enhances VoipSwitch services by enabling reseller accounts structure As shown on a picture below the resellers are divided on three levels with different rights. The
system enables for selling VoIP services through network of service distributors/agent, which
can provision their end-users themselves through the web interface which is part of the module.
The module architecture allows resellers to have own, unique Web Portal module, Online Shop and
branded softphone. Thus, they become in fact virtual VoIP providers based on one, central VoipSwitch,
with possibility to manage the Web Portal (under their own domain name) and integrate with own online
payment processors (e.g. PayPal accounts)
The billing system behind the reseller structure is based on separate rates sheets associated with
each reseller account. The resellers can create own rates sheets for their users or sub-resellers.

a call or many calls, the customer comes to the cash desk where he receives a bill for made
connections. In this scenario, regular phones are replaced by VoIP clients which can be for example
multiple lines FXS gateways, SIP/H323 IP phones (adapters) or even softphones installed on personal
computers (for example in internet cafes).
The whole communication is carried out over VoIP directly between the end-points in Callshop and
VoipSwitch.
