Hi Folks,
I have been doing an installation in Nairobi, nearly finalized but just one item. The very well known problem of the FXO port cannot identify the disconnect message. I read all realted posts applied many solutions. I have captured the voice with Wireshark and analyzed the disconnect signal and applied the below values.
voice class custom-cptone Nairobi
dualtone disconnect
frequency 425 425
cadence 50 50
supervisory custom-cptone Nairobi
voice-port 0/2/0
translation-profile incoming incoming_FXO_to_Reception
supervisory disconnect dualtone mid-call
supervisory custom-cptone Nairobi
supervisory dualtone-detect-params 1
no battery-reversal
cptone KE
timeouts call-disconnect 5
timeouts wait-release 5

Hi,
This is a well known problem with FXO ports
You can use a third party application to solve this issue
Kind Regards

Incorrect. The only solution is to correctly configure the router.

Remove 'cptone KE'. If you have a custom tone configured, you don't need the country's default. Also, a pcm capture is a better indicator of the actual tone recieved than a packet capture.

That is incorrect also.
If you remove cptone, also all the others tones, impedance, and caller ID standards, will be reset to the default of US, that is not desirable.
You can see from any working configuration that it will have cptone AND custom disconnect, working OK.
Secondly. PCM capture and packet capture are exactly equivalent for the purpose of analyzing frequencies. They contain the same data.
