If the VoIP platform requires an prefix for an external call (example: "0"), this can be added automatically by using the Access code functionality.

Access code: Enter the access code for external calls

Add to outgoing call numbers: Activate function with the switch

Length of internal numbers: The number of digits used for internal numbers. The access code is only prefixed if the dialed number contains more digits.

  1. Dial "11" = Internal number of DECT handset, no external call
  2. Dial "88" = Not an internal number, external call "88" without access code as number <= 2 digits
  3. Dial "1234", external call "01234"
