How would I know if an incoming call is from my MobileOffice Plus fixed line telephone number?
You need to turn ON Answer confirmation in the Call Settings > Mobility > Answer Confirmation to distinguish whether an incoming call is from your mobile network or fixed line network (your office phone number). When you answer an incoming call from your fixed line telephone number, you will hear an announcement asking you to press any key to confirm answering the call. When the incoming call is not from your fixed line telephone number, you will NOT hear such an announcement.
What is “Call Transfer”? Does this affect other features?
The “Call Transfer” option must be enabled if you wish to initiate a 3-way conference call. Please note when “Call Transfer” option is enabled, Call Waiting feature of your office phone number will be disabled.
What is Play Ring Reminder when a call is forwarded?
“Play Ring Reminder” option is only available for Infinite Voice users but not available to MobileOffice Plus users.
What is BCP? How can I utilize BCP of MobileOffice Plus?
BCP stands for Business Continuity Plan. If you have turned OFF the Mobility, the incoming call to your office phone number will follow the Call Forwarding (BCP) rule. The default destination is forwarded to your voicemail.
I have set “Call Forward - No Answer” to my office phone number’s voicemail, why is the unanswered incoming call to my office phone number forwarded to my mobile phone’s voicemail instead?
It may be due to the “Number of Rings” in “Call Forward - No Answer” being larger than your mobile phone operator’s value. That means your mobile phone operator’s voicemail is taking the unanswered call before MobileOffice Plus. If you wish to forward calls to your office phone number’s voicemail, we recommend that you try setting a smaller value of “Number of Rings” or enable “Answer Confirmation”. Please check your mobile phone operator about their number of ring values as different mobile operators have different values.
When MobileOffice Plus (signed in) runs in the background, will I be able to receive incoming calls to my office phone number with MobileOffice Plus?
For both iPhone and Android smartphone versions, and under both Internet Call Mode or Mobile Call Mode, you will still be able to receive incoming calls to your office phone number with the App.

*Please note that if you close MobileOffice Plus from iPhone’s multitasking (double-click the Home button) or Android’s recent App list (click the Overview button) under Internet Call Mode, you would not be able to receive calls to your office number until you open the MobileOffice Plus and log in again.
