Callback is a very popular service in many countries of the world because it doesn’t require any investment in a hardware, can be used with any existing phones (both landline and mobile) and can be activated within minutes. Nergy Telecom is one of the leading players on the telecom markets in number of regions enabling its partners to provide various callback services in their home countries.

There are several alternatives to provide callback services

Using a dedicated trigger number scenario (Nergy Telecom calls this service “Callback with dedicated trigger number”)

This service can be provided in any county worldwide. Every account is assigned its own dedicated trigger number. The callback number of the customer should be entered to the platform by the agent manually.

How does Callback with dedicated trigger number work?

  1. Dial the trigger number issued to you when you signed up. The trigger number is an 11-digit number in France like 33-1-xx-xxx-xxx. You will need to dial the prefix required to place an international phone call and then dial the trigger number. You may dial the trigger number from any phone, but our network will call you back to the callback number that you provided when you signed up.

  2. As soon as our network identifies your call you will get disconnected. The trigger number will not ring. Hang up.

  3. Within a few seconds the switch will call you back automatically. Answer the call and enter your destination number. Enter the number you wish to call in the following order: country code + area code or city code + number. Do not enter any prefixes. (Make sure you are using a touch-tone phone).

Using CLI (or ANI) identification. (Nergy Telecom calls this service “CLI Callback”)

This service can be provided in the countries where the local telephone networks do not mask the CLI (Caller Line Identification), that is do not mask the phone number from which the trigger number has been dialed.

How does CLI Callback work?

  1. Dial the global trigger number. You will need to dial the prefix required to place an international phone call and then dial the trigger number.

  2. As soon as our network identifies the phone number from which you are calling the call will be disconnected.

  3. Within a few seconds the switch will call you back automatically to the phone number from which you have dialed the global trigger number. Answer the call and enter your pin code. If the pin code is valid then you will be prompted to enter your destination number. Enter the number you wish to call in the following order: country code + area code or city code + number. Do not enter any prefixes. (Make sure you are using a touch-tone phone).

Using an IP/GSM gateway to process trigger requests and identify customers by CLI (or ANI) (Nergy Telecom calls this service “IP/GSM gateway CLI Callback”)

In most cases, when the IP/GSM gateway is used for callback application, all the CLIs of customers calling either from landline or mobile phones are identified. Therefore the common problem when domestic telephone companies block CLIs when the calls are made to overseas can be bypassed.
