Hipath 4K not disconnecting calls coming through GXW 4108 gateways

[nhlanhla]

Good day.
I have installed a setup similar to Scenario 3 in the attached image.

1)Phone A is an analogue extension connected to a Hipat 4K.
2) The first gateway is connected to analogue extension ports and its a peers to a UCM6510 .
3) The second gateway is connnected to the analogue PSTN trunks and is peered to the UCM 6510 as well.
4)The UCM 6510 has a connection to a SIP provider as well that route all our outbound calls and also has a huge number of IP extensions.

The challenge i have is that calls coming from the PSTN side , route through to the Hipath extensions VIA the two gateways are not getting disconnected on call termination.

please assist to resolve the problem

Configure the analogue extensions on the 4K with the parameter SSTN

(default Y-yes)

ch1-8:N;
(default No; Consult carrier)

(default No; Consult carrier)
Silence Timeout(X1s):
ch1-8:60;
(default 60s)

It would depend on location programming.
Is it working now with SSTN - NOT SSTNO
