Cisco FXO Disconnect Problem

we have 2801 router that connected with 2 anloga lines (FXO Card), but now we have a problem with disconnect problem, the phone still connected after the PSTN Caller Disconnect, and our policy tell that the agents shouldn't end the call, so we want when the PSTN caller end the call we need the phone to return to idle state.

and according for the below link, i configure the custom disconnect tone, and in the attachment you can find tow disconnect tones.

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

the configuration of the custom disconnect tone

voice class dualtone-detect-params 1

cadence-variation 3

voice class custom-cptone Custom1

dualtone disconnect

  frequency 420

  cadence 245 255 245 255 245 255

and the below you can find the configuration of the voice port, and you can find the debug vpm port 0/3/0, debug vpm signal, for a call that disconnected immediately, and for a call the take long time to disconnected.

this is the configuration of the voice port:

voice-port 0/3/0

supervisory disconnect dualtone mid-call

supervisory custom-cptone Custom1

supervisory dualtone-detect-params 1

no battery-reversal

cptone NL

timeouts call-disconnect 5

timeouts wait-release 5

timing hookflash-out 50

timing guard-out 300

caller-id enable

caller-id alerting line-reversal

caller-id alerting dsp-pre-allocate

this is the debug of a call that is disconnected immediately:

Hi All,

 

Even i  have the same issue for the calls. If the prompt is played and if i choose any digits and do it accordingly the call is going to ON HOOK very fast.

If i hear the prompt and i will leave voice message and hang up the call in middle of the call the call is not disconnecting and the second caller calling the number is getting engage tone and that call is not landing the Gateway.

 

Port : 0/2/0

 

Called number : +603 22739788

Hi Sharif,

 

 

You are right the call will not disconnect, 

 

The call flow is  VG >FXO PORT>CUCM(DESKPHONE) if not answered call should forward to voicemail.

It will take around 5 minutes to disconnect the call.
