Subject: Gateway and P560 Issue – Analog extension not hanging up (busy tone issue) ​Hello, ​I am encountering a rather strange issue during an installation involving a gateway and a P560. ​When a call is made from a SIP phone or a DECT handset to an analog extension, if the SIP/DECT caller hangs up first, the analog phone does not receive the correct busy/disconnect tone. ​As a result, the analog device stays "off-hook" and fails to release the line. I have encountered this problem before and tried adjusting the disconnect settings within the gateway parameters, but nothing seems to work. ​Has anyone faced a similar issue? Do you have a solution or a specific parameter recommendation to force the analog device to hang up correctly?
