The call identification is indicated by the COMAND operating, display and controller unit on the display of the COMAND operating, display and controller unit. Additionally, the display of the caller identification is generated via interior CAN on the instrument cluster (A1).

A mobile phone operated with Bluetooth receives the call signal over the mobile phone antenna. Then the call signal is forwarded to the COMAND operating, display and controller unit over the following path:
- Mobile phone antenna
- Bluetooth antenna (A2/91)
- Direct line

On vehicles except code (810) Sound system, the ring tone is transmitted from the COMAND operating, display and controller unit to the following speakers over direct lines:
- Left door speaker group
- Right door speaker group
- Left rear speaker
- Right rear speaker
- Center cockpit speaker (centerfill)
- Left door tweeter
- Right door tweeter

Function sequence, accept call over mobile phone buttons
Pressing the "Accept call" button on the mobile phone serves to accept the call in hands-free mode. The control signals from the mobile phone buttons are internally processed and forwarded to the COMAND operating, display and controller unit over the following path:
- Adapter cable
- Cell phone separation point
- Direct line
- Communication control unit
- Direct line

With a mobile phone operated with Bluetooth, the control signals from the mobile phone buttons are processed internally and forwarded to the COMAND operating, display and controller unit over the following path:
- Mobile phone antenna
- Bluetooth antenna
- Direct line

Function sequence, accept call over telephone buttons or keypad on COMAND operating, display and controller unit
The call can be accepted in the hands-free mode by pressing the "Accept telephone call" button or by selecting the "Accept" function in the "ComTEL/Telephone" menu item over the keypad on the COMAND operating, display and controller unit. The control signals from the telephone buttons or the keypad on the COMAND operating, display and controller unit are processed internally.

Function sequence, accept call over multifunction steering wheel button groups
The call is accepted in hands-free mode by pressing the accept/ terminate phone call button (S111s3) in the corresponding subfield. The control signal from the accept and terminate telephone call button is forwarded to the COMAND operating, display and controller unit over the following components:
- Steering LIN
- Steering column tube module (N80)
- Interior CAN

Function sequence, telephone call in hands-free mode
After accepting the call, the COMAND operating, display and controller unit receives or transmits the mobile phone signals and data over the following path:
- Rod antenna
- Direct line
- Left antenna amplifier module
- Direct line
- Cell phone separation point
- Direct line
- Communication control unit
- Direct line

The voice input in the hands-free mode is received by the hands-free system microphone group (B25) and transferred to the COMAND operating, display and controller unit over a direct line.

On vehicles with code (810) Sound system, the voice output is accomplished by the COMAND operating, display and controller unit, over the MOST and sound system amplifier to the following speakers:
- Left door speaker group
- Right door speaker group
- Left rear speaker
- Right rear speaker
- Center cockpit speaker (centerfill)
- Left door tweeter

Generally, a telephone connection is established in the hands- free mode after accepting a call, regardless or not the mobile phone is connected to the adapter cable.
If a mobile phone connected to the adapter cable is separated from the adapter cable after accepting a telephone call in the hands-free mode, and therefore separated from the COMAND operating, display and controller unit, the telephone call is then continued in the "Private mode". If the mobile phone is connected again to the adapter cable during the course of a call, the telephone call is continued in the hands- free mode again.
With a mobile phone operated with Bluetooth, it is possible to change over to the "Private mode" after accepting a telephone call in the hands-free mode by activating the "Private mode" in the mobile phone when the mobile phone supports the "Private mode".

When in "private mode" the user can make a telephone call without other vehicle occupants being able to hear the conversation.

Function sequence, reject call over mobile phone buttons
Pressing the "End" button on the mobile phone rejects the call. The control signals from the mobile phone buttons are internally processed and forwarded to the COMAND operating, display and controller unit over the following path:
- Adapter cable
- Cell phone separation point
- Direct line
- Communication control unit
- Direct line

With a mobile phone operated with Bluetooth, the control signals from the mobile phone buttons are processed internally and forwarded to the COMAND operating, display and controller unit over the following path:
