26.3 Configuring Hook Flash
The following procedure describes how to configure various hook-flash features.
To configure hook-flash features:
1. Configure the digit pattern used by the Tel side to indicate a hook-flash event:
a. Open the Supplementary Services Settings page (Setup menu > Signaling &
Media tab > Gateway folder > DTMF & Supplementary > Supplementary
Services Settings).
b. In the 'Hook-Flash Code' (HookFlashCode) field, enter the digit pattern.
Figure 26-1: Configuring Hook-Flash Digits
c. Click Apply.
2. Configure the hook-flash transport type:
a. Open the DTMF & Dialing page (Setup menu > Signaling & Media tab >
Gateway folder > DTMF & Supplementary > DTMF & Dialing).
b. From the the 'Hook-Flash Option' (HookFlashOption) drop-down list, select the
required transport type.

c. Click Apply.
3. To configure the period by the device for detecting hook-flash initiated by analog
interfaces:
d. Open the Analog Settings page (Setup menu > Signaling & Media tab > Gateway
folder > Analog Gateway > Analog Settings).
e. Configure the following:
♦ 'Min. Hook-Flash Detection Period' (MinFlashHookTime): Defines the
minimum time (in msec) for detection of a hook-flash event from an FXS
interface. Detection is guaranteed for hook-flash periods of at least 60 msec
(when configuring the period to 25). The device ignores hook-flash signals
lasting a shorter period of time.
♦ 'Max. Flash-Hook Detection Period' (FlashHookPeriod): Defines the
maximum hook-flash period (in msec) for Tel and IP sides for FXS and FXO
interfaces. For more information, see the Telprofile_FlashHookPeriod
parameter in Configuring Tel Profiles on page 471.
