Approximation search

The approximation search attempts to find a company number if an applicable extension cannot be found. A contact must meet the following requirements to be used as approximation result:

• Centres must either have a value in “Company” and no values in “Name” and “First Name”,

• or a value in “Name” and no value in “Company” and “First Name”,

• or a value in “Name” and the same value in “Company” and no value in “First Name”.

• Caller identification

  If this box is checked, the centre number will be displayed if the extension is unknown. Required telephone number format in contacts, e.g.: +49(89)12345-0
