FXO disconnect problem

[nmodarresi]

hello

i have put these commands in my FXO configuration:

timeouts call-disconnect 3

timeouts wait-release 5

timing percentbreak 60

timing guard-out 300

bearer-cap Speech

supervisory disconnect dualtone mid-call

supervisory answer dualtone

pre-dial-delay 2

signal groundStart

but still after a call the line is busy and fxo is off hook for a long time

what can i do next?

If you can figure out the frequneices of the busy tone being played by your telco/pbx you can sue this document to configure the router to drop the call if it hears a tone on that frequency

ALternatively you could purchase an M1 card whcih has support for battery reversal.
