How can I do an external call with the Gigaset SL780 / SL785?

Enter the number and press the talk key.

No dial tone after pressing the talk key?

1. Please note, that you have to press and hold, the talk key to hear the dial tone. By pressing the talk key briefly you will open the redial list from the last 10 numbers.

2. If you press the handsfree key you will hear the dial tone directly.
