Web and desktop callback

Callback module for VoipSwitch enables initiating calls between two telephone numbers, using the callback software installed on the client’s computer or on the web. After being logged, two numbers have to be entered, one in the “destination” field and the other in the “source” field. Clicking on the “call” button will result in initiating connection between the two numbers chosen.
There are two options of carrying out the connection:
Connect source first then call destination
Call simultaneously
In the first one, VoipSwitch will try to connect with the number entered in the “source” field first and then, if this succeeds, will connect with the “destination” field number. In the second options VoipSwitch will try to connect the two numbers simultaneously. In the process of establishing connection user can follow the information on the current connection status both for “source” and “destination” numbers.
In this service, voice is not transferred through the user’s computer but directly through the Voip gateways, with the two parts of the call (connection with “source” and “destination”) sent from VoipSwitch. This ensures the high quality of calls when PC2phone service cannot be utilized (e.g. due to the low internet speed, no audio equipment etc). The picture below illustrates the way callback service operates:

Additional options supported by desktop callback and web callback:
Directory stored on a server
Direct link to the website containing calls history information
Information on the current account status
Real time information of the connection status both for “source” and “destination” numbers
Option of adding funds with the credit card (provided online shop is installed).

Web callback



Desktop Dialer


Callback clients are defined in the “callback clients” menu. It is possible to set up PC2phone client’s account so it can also utilize callback services using one account.
Web and desktop callback can be connected with VoipSwitch’s IVR module what extends their functionality. After having finished the call, or when the connection with the called party could not be completed (e.g. busy line, no answer), IVR acts as a voice prompt which informs the caller to dial another number he/she wants to connect with. Desired number is entered using the telephone’s tone keypad (dtmf). In this way the person who initiates the call can carry out several calls without the necessity of re-launching callback every time. Also, the user can terminate the call without cutting of his/her “leg” by selecting the particular combination of digits (e.g. #1# , which is previous defined in VPConfig) with the telephone’s tone keypad. After terminating the previous call, caller is asked to enter another number he/she wants to connect with.
Additional feature which is supported by IVR is the voice information on the current account status. At any time user can choose a particular number, using tone keypad, e.g. 111 (which is previously defined in VPConfig) to listen to the information on the current account status. In desktop and web callback services the information on the current account status is also displayed in the client software’s interface. 
System has a tool for automatic generation of login/password pairs with an option of exporting data to the file and afterward managing the lots.
User has an option of logging to the website with detailed information on billing. There is also information on the current account status, detailed history of connections and possibility of exporting data to the file.
