tone based ones are supported by whichever IO layer you choose.<br>
For instance if you are using the zt mod (zaptel) then all the low level analog
signalling will be generated by zaptel for ground loop and kewl start etc.<br>
<br>
Tone based hangup detection is a higher level concept that could be implemented
in the core of openzap but would require constant tone detection throughout the
call and is susceptible to false positives etc.<br>
<br>
it's not a common feature where I wrote the code from. I have kewlstart
lines here and nobody has asked for it and I don't have a labbed up example and
I only have 2 hands therefore it's not implemented.<br>
<br>
Like I said using tone_detect in FreeSWITCH with action hangup is not any more
or less glorious than how the feature would work right in openzap so you can
use it that way if you want.<br>

<br>
Thanks for your response. I find strange that this is not a common feature,
it's really difficult to get Telcos to answer to magic words such as
disconnect supervision.<br>
<br>
If tone based disconnect is not used, is "current interrupt" the only
supported disconnect method on a loopstart line or is it polarity reversal
supported as well?<br>

That's why it only works when you use FreeSWITCH to do it in the general
dialplan.<br>
<br>
It's simply a feature we have not had demand for yet in OpenZAP. I'm sure we
could add it if we can find the time/resources.<br>

<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>Hi All,<br>
<br>
I have been working for quite a while in trying to get Openzap to recognize my
country specific busy tone in order to hang up an analog FXO channel.<br>
<br>
Basically, I am having FXO disconnect supervision issues and I wanted to know
if it's possible to hang up the FXO by monitoring call progress tones so that
when there is a busy tone the FXO goes on hook.<br>
<br>
I have been tweaking the /etc/openzap/tones.conf based on the ITU.T
recommendation E.180 for my country, but so far it doesn't even seem that the
changes I make to the tones.conf file are considered when dealing with
disconnects from the PSTN side.<br>
<br>
I restart FS after every change I make to /etc/openzap/tones.conf with no
positive results.<br>
<br>
The Openzap Wiki states that the "loadzone" parameter in
/etc/zaptel.conf is not considered when dealing with tones, which makes sense
since Openzap seems to use libteletone for tone detection and generation.<br>
<br>
Here is what I use for busy tone on /etc/openzap/tones.conf:<br>
<br>
[us]<br>
<br>
generate-busy => v=-7;%(330,330,450)<br>
detect-busy => 450<br>
<br>
Therefore I set openzap.conf.xml as follows:<br>
<br>
<param name="tonegroup" value="us"/><br>
<br>
I was able to check that the busy tone can be detected using the following dial
plan rule:<br>
<br>
1. <extension
name="Inbound"><br>
2.
<condition field="destination_number"
expression="^1$"><br>
3.
<action application="answer"/><br>
4.
<action application"sleep" data="1000"/><br>
5.
<action application="tone_detect" data="busy 450,0 r +100
hangup normal_clearing"/><br>
6.
</condition><br>
7.
</extension><br>
<br>
So that I answer the FXO and hang up when the busy tone is detected. It works
fine and the FXO port does not get stuck.<br>
<br>
Here's the output from the log for the rule above:<br>
<br>
<a href="http://pastebin.com/f43500bd3" target="_blank">http://pastebin.com/f43500bd3</a><br>
<br>
I do not see a reason why settings on tones.conf may not be working?<br>
<br>
Is disconnect on busy-detect the default for Openzap? Is it power denial or
battery reversal?<br>
<br>
Does it matter if I select fxsks in /etc/zaptel.conf instead of fxsls?<br>
<br>
Your help will be greatly appreciated.<br>
<br>
Regards,<br>
<br>
