    Hello Friends,

    Please help for the issue where calls are not getting auto-release even when caller hangs up at his end but the call still shows active on our end (agent end). for Each and every call agents need to press the release button on the phone to release the call. Normally when caller disconnect his call it should also get disconnected at agent end but it is not happening and agent needs to press the release button to disconnect. What could be the possible cause for this?

    Call are coming on one of our CO trunks for which at pbx we have setting for disconnet supervision as flllows:

    Is the CO trunk in service-onhook, or is still offhook?
    Manya More
    I didn't get your question. If you are asking about trunk status, It is in Service.
    Fernando Duran
    My question was about the trunk been still on the call, even if customer already hung up. Like if the trunk is not been released because Avaya equipment is not detecting disconnection.
    Manya More
    Yes, Even though Customer hangs up, call doesn't release at our end itself. After customer hangs up we can hear disconnection tone almost for 1 minute and then it goes on slient but that call still shows active on phone and trunk. We have to manually press the release button on Avaya phone or put the handset back on Phone cradle to release the call. If we forget to release that call manually It remains active.

    Please check in your system-parameter feature if wait answer supervision timer is enabled. It supposed to be in page 10.

    Manya More
    It is already disabled.

    You have to enable it.

    Manya More
    just want to make sure that if I enable it , is it going to affect any ISDN trunks because we have all other ISDN trunks.

    Manya More
    No, not working, I also tried enabling it but same issue.

    Is it in anyway related with physical pair connectivity? I have asked the carrier of that CO trunk to provide trunk settings that they have on their system, but instead of that they carried out testing on that trunk isolating the PBX and as per them issue is at our end. I am pasting below the message content that my colleague sent me after he did testing with carrier technician.

    "The technician came today, I made sure I was with him at all times. We made a test on all lines and the problem comes from the box to the inside of the building. For example: We disconnected a line and left it alone from the street up to the box, then we called the number, answered and hanged up. The line didn’t remain open, but when we connected the internal pair ( the our part) we started getting the error. Calls didn’t get disconnected, even though the caller hangs up, the call still remained open. This is not only something the technician told me, he gave me his handset testing phone and I performed the test and it happened the same.

    So just wondering if it is in anyway related with physical patching, i think it is more related with trunk configuration

    Please advise..

    Hi Umesh. This problem is related to the system not recognizing the disconnect dial tone. I have a document done when i used to work at Avaya Mexico for this to be fixed, but is in spanish, and i dont have the time to translate it to english. If you're interested, send me your email address on a private message and i can send it to you. Check if you can get the translated document from the guy who asked it on this thread.

    Thank you Ferstrange. I have received that document. But is it required any particular privilege to change the system-parameters country option. I can see the settings for country options but when i try to change that it doesn't show country option after I enter command change system paramers

    Please choose from one of the following:

    cdr coverage-forwarding crisis-alert

    Or press CANCEL to cancel the command

    "c" is an ambiguous entry
    Command: change system-parameters c

    I have super-user login privilege on pbx.
    Fernando Duran
    To change country options should be enough with dadmin or craft, or something similar. Also, once measured the time for the disconnect or busy tone, you will have change the system ocm-call-classification, so if your user is not giving you access to those options, then i guess you will have to get someone on Avaya to help you.
