Lines

Setting	Description
Line	Line number. Automatically set when the line was created. Read-only.
Register	Check this box if you want the line to auto-register with the PBX at startup.
Extension	Enter the extension number assigned to the given line. You may already have done so during the Setup wizard or when adding a line, but if necessary you can edit it here as well. Just click on the field and enter the correct extension.
Account	Enter the user name required at login. Field may contain both letters and numbers, but should not contain the domain name. Intended for PBX systems that require TLS. If your PBX does not require lines to log in, leave blank.
Password	Enter the password required at login. Intended for PBX systems that require TLS. If your PBX does not require lines to log in, leave blank.
User Agent	Agent used by the line during registration with the PBX. Some PBX systems use this field for custom configuration; refer to your PBX manual if that is required. The default value `DuVoice` should not be changed unless the PBX requires it.
Display Name	If configured, this value is passed in the P-Asserted-Identity field in the SIP header when making an outbound call. If left blank, the Extension setting is passed instead.

Other than the standard OK and Cancel buttons, three other commands are provided as a convenience:

Command	Description
Auto-Number Extension	This will use line 1's extension number to automatically assign extensions to all other lines, incrementing by one for each successive line. You will be prompted to confirm; click Yes to continue. Example: For a 4-line system, if line 1 is assigned extension `8001`, when you click this button, line 2 will be assigned extension `8002`, line 3 will be assigned `8003` and line 4 will get `8004`.
Auto-Number Account	This will use line 1's account name as a number and set the account name for all other lines based on it, incrementing by one for each successive line. You will be prompted to confirm; click Yes to continue. Example: For a 4-line system, if line 1 is assigned account name `101`, when you click this button line 2 will be assigned account name `102`. Line 3 will get `103` and line 4, will get `104`.
Match Passwords	This will copy the password assigned to line 1 and assign it to all other lines as well. You will be prompted to confirm; click Yes to continue.
