Detect Disconnect
To n e
Choose yes to enable or choose no to disable this feature.
If enabled, the ATA will disconnect both call legs when it
detects the disconnect tone from the PSTN side during a
gateway call. Disconnect tone is specified in the
Disconnect Tone
parameter, which depends on the region
of the PSTN service.
Default setting: yes
Disconnect Tone This value is the tone script which describes to the ATA
the tone to detect as a disconnect tone. The syntax
follows a standard Tone Script with some restrictions.
Default value is standard US reorder (fast busy) tone, for 4
seconds.
Default setting: 480@-30,620@-30;4(.25/.25/1+2)
Restrictions:
• Two frequency components must be given. If single
frequency is desired, the same frequency is used
for both
• The tone level value is not used. –30 (dBm) should
be used for now.
• Only 1 segment set is allowed
• Total duration of the segment set is interpreted as
the minimum duration of the tone to trigger
detection
• 6 segments of on/off time (seconds) can be
specified. A 10% margin is used to validated
cadence characteristics of the tone.
