<DIV><FONT face=Arial size=2> Hi,
</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2> 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.</FONT></DIV>
<DIV><FONT face=Arial size=2>Here is the problem:</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Cisco (as most of the other voice gateways with
analog FXO ports) can not detect the disconnect "tone" from the
Panasonic.</FONT></DIV>
<DIV><FONT face=Arial size=2>Guess why, because the Panasonic PBX does not
send a "busy" tone after the call is completed, but sends an usual
dial-tone.</FONT></DIV>
<DIV><FONT face=Arial size=2>So, what you need is to tune the decadence /
frequency settings in order to have working disconnect supervision.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>Unfortunately, you can not configure the Panasonic
to send "hardware" line supervision signal such as "polarity reversal". In
Panasonic</FONT></DIV>
<DIV><FONT face=Arial size=2>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 </FONT></DIV>
<DIV><FONT face=Arial size=2>ports of the Panasonic to generate polarity
reversal signal once a call is started / completed.</FONT></DIV>
<DIV><FONT face=Arial size=2></FONT> </DIV>
<DIV><FONT face=Arial size=2>I will try to find the frequency/decadence values.
I made it working on a Welltech (Micronet) gateway.</FONT></DIV>

<BR><FONT face="Courier New" size=3>Hello,<BR><BR>I have Cisco1760 with
voice FXO card connected to Panasonic 616. I have <BR>problem when call is
ended on the other side FXO port remains in off-hook <BR>state ad infinity
until it is shuting down manually. I tried any combinations <BR>of
supervisory disconnect settings (signal, anytone, dualtone pre-connect,
<BR>dualtone mid-call) and I also tried every cptone locale settings.<BR>I
see that the router canot recognize BUSY tone from PBX when other side
<BR>closes connection. Where the problem is? Does it have relationship to
the <BR>cptone locale settings? Have I define cptone-custom settings? In
this case I <BR>need freq-pair and cadence settings for all types of
progress tones of this <BR>type of PBX.<BR>My IOS version is 12.2.15T5. I
have the following settings on FXO port:<BR><BR>voice-port
2/0<BR>playout-delay nominal 1500<BR>playout-delay mode fixed<BR>no
comfort-noise<BR>timeouts initial 30<BR>timeouts interdigit 6<BR>timeouts
