Callback Platform SMS/ANI/PIN

Callback module allows for implemenation 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 endpoints on a user request. The types of callback differ in the way of how a user can trigger the service and also they are often divided depending on how the users 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 or GSM 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 CallerID (ANI): The system tries to authorize the Caller ID received with the triggering call, if authorization is successful (the callerid 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 dialling this DID the system initiates a call to a predefined phone number associated with the account (not the callerID). This service is mainly for users that for requesting callback use phone services with blocked callerID.

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 is renting the SMS number from SMS provider which will forward incoming text messages to specified VoipSwitch URL. More information about possible SMS commands are in the SMS callback section.
Authorization in this method can be by CallerID 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.
