Advantages of using CallBack function

Bellow you can find some exemplary advantages of using CallBack function:

  • Transit calls, so realizing official calls from phone located outside of PABX is limited to phones with number defined in PABX data base. There is no possibility to loose password or breaking system protections.
  • As user is no charged for calls, private GSM numbers can be defined as MobilePhone numbers, so there is no necessary to increase number of company's GSM phones.
  • Call is always established by PABX, so there is no presentation of caller. Person who answered call can only recognize that caller is somebody from inside company. Due to this functionality number of GSM phones (official and private) are always hiden.

CallBack function operating

CallBack is a PABX service which enables - using phone outside PABX - to order PABX establish a call to other user outside the PABX with charging extension number with entered in field MobilePhone number from which call is ordered. CalBack function aperates in following way:

  • From phone defined in PABX as MobilePhone to number assigned by admin to this function.
  • PABX refuses this call - it takes place after two ringings, unless caller hang up the phone.
  • After short time (as standard delay is set to 5 seconds) PABX rings back to MobilePhone number. Caller presentation is the same as number assigned by admin to CallBack service.
  • After answering call standard PABX dialing tone can be hear. During this signal target subscriber number can be dialed.
Warning! Benefits which can be obtained while using CallBack service are specially visible for calls with roaming fees. Łączny koszt połączenia zostaje znacznie obniżony dzięki tej funkcji. If MobilePhone is abroad, call established using from this phone to another number in the country where PABX is located is much more cheaper that call without using this service. For instance for Poland call inside EU costs 1,79 PLN/min. Using CallBack service, the same call costs 0,85 PLN/min (with assumption, that outgoing calls from PABX to MobilePhone is costless).


CallBack function settings

Cały sposób działania funkcji Callback zdefiniowany jest w centrali i tylko administrator może go zmieniać. Administrator decyduje o:

  • Numerach wewnętrznych dla których opcja będzie dostępna
  • Numerach zewnętrznych ( stacjonarnych lub GSM) na które centrala oddzwoni po wywołaniu funkcji Callback
  • Numerach miejskich centrali na które należy dzwonić aby wywołać funkcję
  • Z jakiego numeru centrala oddzwoni do użytkownika realizując funkcję Callback

Limitation in CallBack service operation

Warning! CallBack service requires license code. DEMO mode enables to launch service for one extension number


Warning! For proper CallBackfunction operate, it is required to use ISDN, embedded GSM or VoIP trunk.

W przypadku wywołania funkcji z wykorzystaniem dwóch linii analogowych działanie funkcji będzie ograniczone ( maksymalny czas trwania rozmowy do 3 minut).W zależności od jakości łączy, telefonu na który nastąpi oddzwonienie, oraz numeru który zostanie wybrany przez osobę dzwoniącą połączenie może być złej jakości a czasami niemożliwe - i to nie może stanowić podstaw reklamacji lub roszczeń.
Dlatego do poprawnego działania funkcji zaleca się, aby do realizacji połączenia co najmniej jedna z używanych linii była linią:

  • ISDN,
  • wbudowaną bramką GSM,
  • dobrej jakości połączeniem VoIP.
