• Incoming/Outgoing call log information is stored on the phone, not on the PBX.
• Automatic Rerouting to Secondary PBX
A
KX-UT series SIP phone can automatically connect to a secondary PBX if its primary PBX goes offline.
When the primary PBX is available again, the phone reconnects to it. (® 2.1.7 Automatic Rerouting to
Secondary PBX)
• For detailed explanations about a particular KX-UT series SIP phone, refer to the telephone’s
documentation.
• DSP Resource Usage
Making a call from a SIP extension requires a certain number of DSP resources, depending on the codec
used. If all DSP resources are in use, this operation cannot be performed. To ensure a minimum level of
performance, DSP resources can be reserved for VoIP communication. (® 5.1.18 DSP Resource
Usage)
However, DSP resources are not required for P2P calls. (® 15.1.5 Peer-to-Peer (P2P) Connection)
