Preferred-Numbers

Enter emergency phone numbers in this table. If a call to an emergency number cannot be established due to an error message from the SIP provider, an existing call that is using this line (line type Trunk/Flex) or the associated line group (line type Single Account/Provider) will be terminated. This ensures that a voice channel is available for the emergency call.

A line group is defined in the "Dynamic SIP Lines" table. SIP lines with the same "Dynamic-Line-Name" belong to the same group. Typically, these are multiple individual numbers that together provide a certain number of voice channels.
