The phone keep ringing eventhough the caller hangs up

I have 3825 CME with CUE, when a caller call and the autoattended played and route to whatever extension he want, and the caller hang-up before answering the phone keep ringing with no end.

I tried to configure the FXO to one of extension directly without autoattendant it worked fine “disconnect directly”.

I have attach you “show run” and “debug vpm signal”

You need to enable supervisory disconnect on the fxo port.

Try these configuration for disconnect:

voice-port 0/2/0
supervisory disconnect dualtone mid-call
cptone BR
timeouts call-disconnect 1
timeouts ringing 5
timeouts wait-release 1

It works on most of my configured FXO voicegateway.

Re: The phone keep ringing eventhough the caller hangs up

Re: The phone keep ringing eventhough the caller hangs up

Hi,

If your configuration is exactly like this:

voice-port 0/2/0
supervisory disconnect dualtone mid-call
cptone BR
timeouts call-disconnect 1
timeouts ringing 5
timeouts wait-release 1

May be your frequency and cadence is wrong. Please make a custom tone and re-apply it to your voice-port.

For example:

*** please note that the parameters are for Vietnamese telco only ***

voice class custom-cptone vn
dualtone disconnect
  frequency 425 425
  cadence 500 500 continuous

!

voice-port 0/2/0
supervisory disconnect dualtone mid-call
supervisory custom-cptone vn
no battery-reversal
timeouts call-disconnect 0
timeouts ringing 5

timeouts wait-release 1

Re: The phone keep ringing eventhough the caller hangs up

Note that the frequency and cadence I posted are just example. You need to find exactly what your parameters are.

Method 1: Ask your telco

Method 2: Get it yourself by capture the tone and analyze by some tools like CoolEdit Pro... If you need to do it, please contact me for the steps.

Re: The phone keep ringing eventhough the caller hangs up

Hi,

Sorry for late I was in vacation, now could you please help for the step to get the frequency and cadence.

And one more thing is this frequency and cadence effect on caller-id.

Appreciate your help.

Re: The phone keep ringing eventhough the caller hangs up
