User's Manual
For analog interfaces: Defines the digit pattern that when
received from the Tel side, indicates a Hook Flash event.
For digital interfaces: Defines the digit pattern used by the PBX to
indicate a Hook Flash event. When this pattern is detected from
the Tel side, the device responds as if a Hook Flash event has
occurred and sends a SIP INFO message if the HookFlashOption
parameter is set to 1, 5, 6, or 7 (indicating a Hook Flash). If
configured and a Hook Flash indication is received from the IP
side, the device generates this pattern to the Tel side.
The valid range is a 25-character string. The default is a null
string.
Note: This parameter can also be configured in a Tel Profile.
Defines the hook-flash transport type (i.e., method by which hook-
flash is sent and received). For digital interfaces: This feature is
applicable only if the HookFlashCode parameter is configured.
