A PS destination can be used to forward fax calls to a fax machine at another PBX connected by TIE line.
A
virtual PS can be specified as the destination of fax calls. Then, the extension number of the fax machine at the other PBX can be
specified as the FWD—ALL Calls destination for calls to that virtual PS. (® 21.1.2 Virtual PS)
Conditions
• This feature is only effective for calls arriving on DISA lines.
• If a fax signal is not detected before the DISA Intercept Routing—No Dial timer expires, the call is redirected
to the operator extension, and fax detection ends.
• If the fax tone (CNG signal) detection is delayed because of the fax machine type or the state of the line,
the DISA intercept timer may time out and the fax cannot be received. In this case, increasing the DISA
intercept timer by 5 to 10 seconds will help avoid this problem.

2.1.7 Automatic Rerouting to Secondary PBX
Description
If an IP extension loses its connection to its primary PBX, it can automatically reconnect to a specified
secondary PBX. The connection can be lost due to factors such as network outages or the PBX going offline.
When the primary PBX is available again, the extensions automatically reconnect to it.
