Parameter Description
Hook-Flash Parameters
Hook-Flash Code
configure voip > gateway dtmf-supp-
service supp-service-settings > hook-
flash-code
[HookFlashCode]
Analog interfaces: Defines the digit pattern that when
received from the Tel side, indicates a Hook Flash event.
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: The parameter can also be configured in a Tel Profile.
