Irrespective of the type of vehicle-related service rendered (e.g. MB-Info call), once the SMS has been sent an immediate voice contact is established with the CAC whereupon the customer can talk to a service receptionist.

Voice connection function sequence
The voice control system microphone (B25/7) is used for voice commands; it is integrated into the overhead control panel control unit (N70). The signals from the voice control system microphone are sent via a discrete line to the "master control unit".
The "master control unit" then loops through the voice control system microphone signals and forwards them to the communication module integrated into the emergency call system control unit.

The communication module integrated into the emergency call system control unit transmits the voice control system microphone signals to the CAC. The communication module integrated into the emergency call system control unit transmits and receives the mobile phone signals or data in the following way:
^ Discrete line
^ Frequency switchover control unit (N96), with code (389) Mobile phone preinstallation with universal interface, USA/ Canada
^ Discrete line
^ Multifunction antenna (A28/11)

Voice output takes place exclusively via the center instrument panel speaker (H4/27). This is read in via a discrete line by the emergency call system control unit.

At the same time, the emergency call system control unit in vehicles with code (810) Sound system sends a mute signal via a discrete line to the sound system amplifier control unit (N40/3) to mute the following speakers:
^ Left front door speaker (H4/1)
^ Right front door speaker (H4/2)
^ Left rear door speaker (H4/3)
^ Right rear door speaker (H4/4)
^ Bass speaker (H4/29)
^ Left rear surround speaker (H4/54)
^ Right rear surround speaker (H4/57)

Normally the voice connection is deactivated by the CAC.

The voice control system microphone consists of 2 microphones. However, only one microphone is used for voice input.

The establishment of a voice connection to the CAC is interrupted by the communication module integrated into the emergency call system control unit after several unsuccessful dialing attempts.

In the event of a malfunction in the multifunction antenna (e.g. defective because of a rollover), the communication module integrated into the emergency call system control unit automatically sends and receives the mobile phone signals and data via the emergency call system antenna (A2/52).

For vehicles without code (810) Sound system, the emergency call system control unit sends a mute signal via a discrete line to the "master control unit" to mute the following speakers:
^ Left front door speaker
^ Right front door speaker
^ Left rear door speaker
^ Right rear door speaker
