Configuration Settings
These settings are mergeable with the exception of the Line Number setting. Changing the Line Number setting requires a “merge with service disruption”. When the configuration file is sent to the system, the SIP trunk is restarted and all calls on the line are dropped.
Offline editing is not required.
Field
Description
Line Number
Default = Auto-filled. Range = 1 to 249
Enter the line number that you wish. Note that this must be unique. This value is used as the incoming group ID for the line needed for incoming call routing.

Set the format the IP Office uses for SIP URI entries in headers.
SIP URI - Use SIP URI format. For example, display <sip:content@hostname>
Tel - Use Tel URI format. For example, +1-425-555-4567. This affects the From field of outgoing calls. The To field for outgoing calls uses the format specified by the short codes used for outgoing call routing.

Location
Default = Cloud.
You can set Location values for the IP Office system and for individual extensions and lines. Associating a line with a location:

Layer 4 Protocol
Default = TLS
Fixed value. Not changeable.
Use Network Topology Info
Default = None.
LAN1 - Associate the line with the Network Topology and DiffServ Settings settings of IP Office LAN1.
If no STUN server address is set for the LAN interface, then the Binding Refresh Time is ignored when calculating the timing for periodic OPTIONS messages unless the Firewall/NAT Type is set to Open Internet.
LAN2 - As above but using the settings of IP Office LAN2.
None - If selected, the IP Office does not apply STUN lookup. The IP Office system IP routing tables determine routing for the line.
