I have a tricky issue where outside caller calls in and when the call is forwareded to voicemail because of CFNA, the FXO do not disconnect. I have a setup where a Etisalat Analog lines are directly connected to UC560 FXO ports using RJ11.
When a call comes in over the PSTN to an FXO port on my UC560 and the call is answered by the user and after that user goes on-hook, FXO disconnects or gets released normally . When the user does not answer the call and becuse of CFNA timeout the call is forwarded to users voicemail box , then CUE answers, a voicemail is recorded, but when the calling party hangs up FXO doesnot disconnect instead it stays in OFFHOOK state (HANGS). Because of this no more calls are possible on that FXO line. I have to issue shut and no shut command on the FXO to get it released.
The IOS version as follows
uc500-advipservicesk9-mz.151-2.T4
and CME and CUE version are as follows 8.0.2
The follwing is the configuration on my UC560

I have this problem only when the call is passed to CUE and this redirect the call ( for example press 1 for Sales). This is a strange problem in the cue setting.

I have some news.
I have tried with a gateway fxo Linksys SPA 3102 connected via Sip to UC560.
If I change the parameter of Disconnect Tone in :
Whit gateway everything work fine !
This parameter is corresponding to configuration of the FXO integrated in the UC560:
voice class custom-cptone IT-CUSTOM
dualtone disconnect
frequency 425
cadence 200 200
!
voice-port 0/1/0
trunk-group ALL_FXO 64
supervisory disconnect dualtone mid-call
supervisory custom-cptone IT-CUSTOM
input gain 14
cptone IT
timeouts call-disconnect 2
timeouts wait-release 2
connection plar opx 396
impedance complex2
caller-id enable
!
But not working !
Where is the problem !?!?

This is the magical paramenter :
!
voice class dualtone-detect-params 1
freq-max-deviation 50
!
voice-port 0/1/0
supervisory disconnect dualtone mid-call
supervisory custom-cptone IT-CUSTOM
supervisory dualtone-detect-params 1
!
Im realy realy happy ! Maybe the CUE manipulates this frequence in some way.

Hi Paolo Moserle,
I am glad that you have resolved the issue. You should have tried this first as it is marked as the correct answer.
Just to add - the CUE is not manipulating the frequence. It just has longer disconnect timeout. That is why the CME should correctly recognize the disconnect tone to act on time without waiting to disconnect from the called side.
Best regards,
Alex

Some times the error still occurs, I suggest you to switch the number in a sip trunk. In my experiences I find many problems to configure FXO in Italy, where in other country there are not!

Hello Paolo,
same configuration but not works : (
yes, i would like that the customer change the connection to provider with a SIP trunk but still wants to use analog line for backup.
Another problem is that if the user with IP phone is busy the called always hears ringback :(

Really annoying problem. The only thing that I can suggest you, is to try with a different gateway, like a patton, in front of the router.

this really works! thank you. who knows what this parameter does?

Dear All,
I solved the issue.
I am from Saudi Arabia. I use STC analog lines at my office. And this command under my voice port worked like a charm. Hope it helps
