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.

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.
