The DTMF and hook-flash parameters are described in the table below.
Table 58-42: DTMF and Hook-Flash Parameters
Parameter Description
Hook-Flash Parameters
Hook-Flash Code
[HookFlashCode]
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.
Hook-Flash Option
[HookFlashOption]
Defines the hook-flash transport type (i.e., method by which hook-flash
is sent and received).This feature is applicable only if the
HookFlashCode parameter is configured.
