Incoming calls don not disconnect

[EchoSpark]

Hello all,
when incoming calls are made to the auto attandant on the PBX, and the caller enters the desired extension. The call continues to ring endlessly at the extension even after the caller has dropped, if no body picks it up.

My trunk config is as follows

Can someone please help me solve this problem

Are you trying to do a double cover? Becuase that is not allowed.

Perhaps I didnt give a good description of the problem.

When i call in, and i dial my desired extension. The phone rings at the extension and then I drop the call. But the phone continues to ring at that extension indefinitely even after i have dropped the call at my own end.

And when someone picks up the ringing phone, its just silent.

Turn off "receive answer supervision".
The switch times out after 10 seconds and assumes the call is connected. This usually will not work with "loop-start" lines, even with "disconnect supervision". You are in effect playing "confuse-a-switch" with two conflicting features. Loop start lines do not respond to answer supervision, they have three states "ringing", "connected", "disconnected" (idle), If you fake it out with answer supervision, it will remain connected and ringing, because it is doing what you told it to.

Thanks guys, i turned off 'recieve answer supervision' and left the disconect supervision. But its still the same. i heard there's some field in the System parameters features page that i ought to change?

I just noticed that you have "direction" in the trunk print above as "incoming", yet you have "outgoing display" as yes and "dial-access" as yes.
A loop start CO trunk should be set as "two-way", this is not a DID trunk, or WATS trunk.
Setting this as "incoming" (only) creates a different set of parameters for the trunk group, and may interfear with proper disconnect.
Generally, for loop start trunks, leaving all the settings at default, except for dial access, l/d "1" required, and toll restricted (as required)should suffice for most operations.

The only thing I can think of in system para features might be "ACA" (automatic circuit assurance) and you have it administered, therefore it could have some bearing on long and short holding times and trunk operation, in addition to the above.

I have now created a new trunk group.And the parameters are default.

The problem persists. I really dont know what to do any more.
