Using an SBC (Session Border Controller)
KX-UT SIP phones and general SIP phones support simple remote connectivity when the PBX is networked
with an SBC (session border controller). Simple remote connectivity means that even if the SIP phone is located
behind a NAT router, firewall, or both, specialised settings such as NAT traversal settings do not need to be
configured for each remote extension.
There are 2 scenarios for configuring and connecting a SIP phone:
a.
The SIP phone is connected and registered to the PBX on the PBX's local network. The necessary settings
are configured automatically by the PBX.
b.
The remote IP settings of the SIP phone are configured without first connecting the phone to the PBX.
Once programmed, the SIP phone is sent to the remote location, connected to the network and will
automatically connect to the PBX.
