Hi,

this is a well known issue in FXO setup. the disconnect signal it depends on the PBX you are connected from PSTN provider. the disconnect signals are different from one vendor to other, Ericson, Siemens, Alcatel,... etc.

You need to take the appropriate disconnect signal from your PSTN provider if it is possible.

you can use the following link to look for your current disconnect signal

http://www.3amsystems.com/wireline/tone-search.htm?start=0&kCountry=92&kTone=10

if one of the above is not working you need to take pcm captures, find the below link

http://ciscoflair.blogspot.com/2009/05/cisco-fxo-disconnect-issue.html

to take pcm capture use the following command

1. Enable the capture:

    Router(config t)#voice hpi capture buffer 5000000

    Router(config t)#voice hpi capture destination flash:FileName.pcm.dat

2. Start the capture:

    Router#test voice port x/y/z pcm-dump caplog 7

3. Place a call on that port, and disconnect from the far end.

4. After the call has been disconnected from the PSTN side, disable the capture with the command below.

   Be sure to do this, or otherwise the router flash will be full and the router will hang.

   Router#test voice port x/y/z pcm-dump disable

   Router(config t)#no voice hpi capture destination

5. Please send me this .dat file with the bad capture so I can extract it into PCM audio files.

HTH
