Making calls with ease
Mobile system subscribers (MMA)
Use callback
Dial the dial-in number of your system, e.g. 069 7505,
from the registered external telephone with callback activated.
Wait for a ringback tone. After a short time, the Integral 5 disconnects. You will hear
the busy tone.
Replace the handset. Your system will ring you back after about 10 seconds.
Lift the handset. You will hear the dial tone and you can now make calls as if you
were an internal subscriber. Any call charges incurred are charged to your system.

Note
• Your system administrator will give you the dial-in number.
