Supporting messages and calls

For call between two users necessary are:

  • proper account configuration of application and PBX
  • full connection between application and PBX(full data synchronisation of application with PBX) - application icon should have green color
  • installed Slican system phone, VoIP or analog phone for IPx, MAC or NCP PBX or configured MessengerCTI subscriber((only NCP PBX)

Making calls

Two ways of making calls:

  • from Contacts tab - choosing subscriber from particular group (if applicable), or from "All contacts" group. Call is made by touching contact tab, then choosing icon from drop down menu.
  • from Contacts tab- searching for phone number in Search field by using keyboard then touching lower right corner of keyboard
MessengerCTIM out ext1.png
  • from Last/Recent - find subscriber which we had shared call(he called or we called him) and then make call by touching middle part of contact tab and choosing action from drop down menu
MessengerCTIM out number1.png

Connecting calls are displayed with call screen just like calls made using GSM. Application at first is connecting call to PBX dedicated number for MessengerCTI.Mobile users, configured by PBX administrator. Then PBX is connecting by transit to number chosen by MessengerCTI.Mobile. Due to that reason, required city line for PBX must be at least ISDN BRA.

Incoming calls

Incoming calls are displayed with popping up call window and ring tone configured in application notifications settings. Calls are received by sliding icon with green handset, if we want to reject call it can be done with sliding red handset. If additional handy numbers were set, call may be forwarded to them by sliding icon with handy number. Process of receiving incoming calls works by making a return call with GSM line to application access number defined by PBX administrator.

Missed calls are displayed with icon MessengerCTIM no answer qty.png. Going to call history or calling back will clear information about amount of missed calls.

Messages support

Application allows to send and receive text messages between MessengerCTI.Desktop/Mobile user (internal chat). To send message user status icon must be touched or from drop down menu and touching contact tab, then choosing chat.
Receiving messages is displayed on notification bar by proper icon and defined ring tone.
If subscriber is using both versions of MessengerCTI, messages history is stored locally in MessengerCTI.Dekstop application.
