Customer call in to system TDE600 via CO trunk -> HDV130 ringing long time

[Duc Cuong]

Hi

I have used Panasonic TDE600 and all of SIP phone HDV130
and now i have issue: When customer call in to system via CO trunk (ELCOT16) hear voice guide and press extension SIP phone HDV130 (Extension 888), and then customer disconnect the phone, the Extension 888 ringing long time (some hours)

Could you please help to reduce the ringing if customer disconnect the call first

Noted: Host (PSTN) not support polarity Reversal

Thanks

In 4.Extesion/1.Wired extension/1.Extension setings/Intercept destination for every EXT set destination number (D/L/B/N) of ISND modem or not connected digital phone. In a Intercept No Answer time set time to intecept, if "0" then PBX uses time from 2.System/3.Timers & counters/ IRNA time (D/L/B/N), default is 40 sec.
