Hi,
I was fighting such an issue with KX-TD500 and KX-TD1232 more than two years
. There is a solution, but not an universal one.
Here is the problem:
Cisco (as most of the other voice gateways with analog FXO ports) can not de
tect the disconnect "tone" from the Panasonic.
Guess why, because the Panasonic PBX does not send a "busy" tone after the c
all is completed, but sends an usual dial-tone.
So, what you need is to tune the decadence / frequency settings in order to
have working disconnect supervision.
Unfortunately, you can not configure the Panasonic to send "hardware" line s
upervision signal such as "polarity reversal". In Panasonic
you can purchase an FXO-port card that can detect polarity reversal from the
other side (usually - the PTT), but you can not configure the FXS
ports of the Panasonic to generate polarity reversal signal once a call is s
tarted / completed.
I will try to find the frequency/decadence values. I made it working on a We
lltech (Micronet) gateway.

Subject: [cisco-voip] FXO disconnect problem with Panasonic KX-TD500
We have a cisco 2800 with a FXO card connected to a Panasonic KX-TD500, with
the same problem presented by Juraj Kovac around a year ago.
Has anyone solved this problem?
Thanks in advance,

Hello,
I have Cisco1760 with voice FXO card connected to Panasonic 616. I have
problem when call is ended on the other side FXO port remains in off-hook
state ad infinity until it is shuting down manually. I tried any combination
s
of supervisory disconnect settings (signal, anytone, dualtone pre-connect,
dualtone mid-call) and I also tried every cptone locale settings.
I see that the router canot recognize BUSY tone from PBX when other side
closes connection. Where the problem is? Does it have relationship to the
cptone locale settings? Have I define cptone-custom settings? In this case I
need freq-pair and cadence settings for all types of progress tones of this
type of PBX.
My IOS version is 12.2.15T5. I have the following settings on FXO port:
voice-port 2/0
playout-delay nominal 1500
playout-delay mode fixed
no comfort-noise
timeouts initial 30
timeouts interdigit 6
timeouts wait-release 10
description ### Extension 17 ###
supervisory disconnect dualtone mid-call
no battery-reversal
---> cptone US default
I am including tracing of the problem:
When all is idle:
prompt>sh voice call sum
PORT CODEC VAD VTSP STATE VPM STATE
============== ======== === ==================== ======================
2/0 - - - FXOLS_ONHOOK
2/1 - - - FXOLS_ONHOOK
I am calling extension 17:
prompt>sh voice call sum
PORT CODEC VAD VTSP STATE VPM STATE
============== ======== === ==================== ======================
2/0 - - - FXOLS_WAIT_RING_MIN
2/1 - - - FXOLS_ONHOOK
after 1st ring router responds with dial tone:
prompt>sh voice call sum
PORT CODEC VAD VTSP STATE VPM STATE
============== ======== === ==================== ======================
2/0 None y S_DIGIT_COLLECT FXOLS_PROCEEDING
2/1 - - - FXOLS_ONHOOK
I hang up the phone. Router waits 30 s for digit collection (timeouts
initial). After this timeout router enters WAIT_RELEASE state:
prompt>sh voice call sum
PORT CODEC VAD VTSP STATE VPM STATE
============== ======== === ==================== ======================
2/0 None y S_WAIT_RELEASE_NC FXOLS_PROCEEDING
2/1 - - - FXOLS_ONHOOK
In this state router remains ad infinity.
Thanks,
