External SIP Phones
The LT-4100 system is supporting connection of external SIP phones, up to 8 external SIP phones. The
configuration of the SIP phones must be completed via the web server, see
is illustrating the connection of the external SIP phones. Connect the SIP phones directly to the LT-4110
Control Unit Ethernet (LAN port).
NOTE
:
The SIP phone might require a DHCP Server to get an IP address assigned. Depending on
network setup, it might be needed to configure DHCP Server mode in the LT-4100 system.
The LT-4110 Control Unit UI display (MENU -> System -
> SIP Phones) will provide a ‘live’ registration status
of the SIP phones configured from the web server.
An active voice call to/from a SIP phone is not shown on the Control Unit on Certus, see Figure 47.
