Call forking to fixed and mobile terminals & Unique voicemail

Call forking allows you to send a call to a group of fixed and mobile terminals simultaneously, through a single telephone number.  For example, this allows the user to have his mobile phone, desk (SIP) phone, tablet etc., connected to a single number, with a converged voicemail for all terminals.




Voice call continuity

Voice call continuity allows the user to switch between terminals during a call, without interrupting it.

For example:
  • The Salesman is on a call with the Customer on his fixed phone but he has to leave the office.
  • Salesman presses a key on his mobile phone to pull the call. GTS Centrex allows Saleman’s mobile to join the conversation transparently for the remote party.
  • The Salesman leaves the office and continues his call with the Customer from his mobile.
