Automatic Rerouting to Secondary PBX

When the primary PBX is available again, the phone reconnects to it. (® 4.2.3.2 Automatic Rerouting to
Secondary PBX)

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. (® 5.5.4 DSP Resource Usage)
However, DSP resources are not required for P2P calls. (® 5.2.3 Peer-to-Peer (P2P) Connection)
