•	Line Number: Default = Automatically assigned. By default a value is assigned by the IP Office. This value can be changed but it must be unique.

•

Network Type: Default = Public, Software level = 4.2+.
This option is available if Restrict Network Interconnect (System | Telephony | Telephony) is enabled. It allows the trunk to be set as either Public or Private. The IP Office will return number unobtainable indication to any attempt to connect a call on a Private trunk to a Public trunk or vice versa. This restriction includes transfers, forwarding and conference calls.

•	Due to the nature of this feature, its use is not recommended on systems also using any of the following other IP Office features: Small Community Networks, VPNremote, Phone Manager telecommuter mode.

•	SES Domain Name: Default = Blank. This field is used to enter the domain part of the SIP URI provided by the ITSP. For example, in the SIP URI mysip@example.com, the domain part of the URI is example.com. For outgoing calls the user part of the SIP URI is the Branch Prefix and the extension number.

•	SES Address: Default = 0.0.0.0 This value is the public IP address of the SES server. This address must not be shared by any other IP, IP DECT or SIP line in the IP Office system configuration.

•	Inactivity Timeout (seconds): Default = 120, Range = 0 to 99999 seconds. If no SIP messages or signalling have been sent or received during this period the IP Office will close the connection.

•	Outgoing Group: Default = 0, Range 0 to 99999. Short codes that specify a number to dial also specify the line group to be used. The IP Office will then seize a line with a matching Outgoing Group ID.

•	Prefix: Default = Blank. This prefix will be added to any source number received with incoming calls. Normally this should match a dialing short code configured to route matching calls to the SES line's Outgoing Group ID number.

•	Max Calls: Default =10 This field sets the maximum number of simultaneous calls that can use the URI before the IP Office returns busy to any further calls.

•	In Service: Default = On. When this field is not selected, the SIP trunk is unregistered and not available to incoming and outgoing calls.

•	Use Network Topology Info: Default = LAN1 For various settings, this field indicates whether the SES line uses the System \| LAN \| Network Topology settings of either LAN1 or LAN2. For instance the DiffServ Settings applied to outgoing SES calls and the IP address (see description of Via Nat below).

•	Via NAT: Default = Off. This option controls which address should be used as the IP address of the IP Office system that is entered into the SES server configuration.

•	If disabled, the address used is the IP Address of the IP Office system as set on the LAN Settings sub-tab of LAN1 or LAN2. The selection of LAN1 or LAN2 is determined by the Use Network Topology field above.

•	If enabled, the address used is the Public IP Address as set on the Network Topology sub-tab of LAN1 or LAN2. The selection of LAN1 or LAN2 is determined by the Use Network Topology field above.

Prefix Allocation Check
As SES lines are configured within each IP Office system in the SIP for Branch network, details of the IP Office system can be written to a CSV file. This file can then be used to ensure the following:

Check branch allocation
Check that the settings of the IP Office and SES line being added are both complete and do not conflict with those of other IP Office systems already added to the CSV file. Select this option and click Execute , then select the CSV file containing details of the other IP Offices with SES lines.

List branch allocations
Provide the source of the details that need to be entered in the SES server configuration for each IP Office. Select this option and click Execute to select and display the CSV file containing details of existing IP Office SES line settings. This file provides the information necessary for matching line entries in the SES server configuration.
