Installing KX-UT series SIP phones at a remote site
There are 2 methods to install KX-UT series SIP phones at a remote site:
• Set
up KX-UT series SIP phones at the main site using the KX-NS500, and then send them to the remote
site.
• Set up KX-UT series SIP phones without connecting them to the KX-NS500 at the main site, and then send
them to the remote site.
Setting up KX-UT series SIP phones at the main site, and then sending them to remote site
1. Register the KX-UT series SIP phone. For details, refer to "5.8.1 Registering IP Telephones".
2. Program the settings for the KX-UT series SIP phones.
a. Click Setup ® PBX Configuration ® Configuration ® Slot.
b. Place the mouse cursor over the Virtual Slot, and in the menu that appears, click Select Shelf.

A menu will be shown under the mouse pointer.
d. Click Port Property.
e. Click Remote Place tab.
f. Configure the items shown below.
• Select a protocol (HTTP/HTTPS) for Protocol for Remote SIP-MLT.
Note
When a
SIP phone at remote site uses the internet to communicate with a KX-NS500 , use the
HTTPS protocol for security. If the connection is on VPN and protected, you may use the HTTP
protocol.
• Change the value to Remote (SBC) for Phone Location.
g. Click OK.
3. Unplug the AC adaptor of the KX-UT series SIP phone, and then plug it in again to reboot the KX-UT series
SIP phone manually.
The KX-UT series SIP phone will download settings automatically.
Note
• After downloading
the setting information for the remote site, the KX-UT series SIP phone will not
connect to the KX-NS500 if it is connected to the LAN at the main site. After some time, the
KX-UT series SIP phone will display "9002: Connection Failed".
• Depending on the settings of your router, the KX-UT series SIP phone may connect to the PBX. In
such cases, proceed to step 4.
4. Send the KX-UT series SIP phone to the remote site and connect it to the LAN in the remote site.
Note
The KX-UT
series SIP phone is already registered to the KX-NS500 and programmed with the remote
site configuration. There is no operation required for the KX-UT series SIP phone at the remote site.
