The SIP Trunk Settings page is used to enable the Bizfon as a 
slave or master device for SIP trunking. The page consists of 
the following components: 
The  Enable Trunks to Slave Devices checkbox enables the 
Bizfon as a master device and allows you to configure the SIP 
trunks to the slave Bizfons. When this checkbox is enabled the 
Trunks to Slave Devices table needs to be configured. 
The link Trunks to Slave Devices moves you to the page 
where a list of slave devices needs to be defined.

The Add Entry page consists of the following components: 
The SIP Trunk Name text field requires the trunk name for the 
corresponding connection. System suggests you to start the SIP 
trunk name with the “SIP_Trunk_” words, according to the 
automatic prefix used for the SIP trunks on the Bizfon, however 
this is not mandatory. 
The  User Name text field requires the authentication user 
name. The field in front of this text field displays the default non-
editable prefix for SIP trunks: “SIPTrunk_”. 
The Password text field requires the authentication password. 
Please Note:
 The User Name and Password should match 
both on master and slave Bizfons for the successful SIP trunk 
establishment. 
The  Symmetric NAT checkbox should be selected when the 
slave Bizfon is located behind the symmetrical NAT.
