<p class=MsoNormal><font size=3 face="Times New Roman"><span style='font-size:
12.0pt'>I understand that tone based disconnect could be subject to false
disconnects in some cases, being dependent on the integrity of the analog
signal and the proper configuration of tones, however I do feel that the
feature is worth the effort, considering how difficult it is to get a Telco to
arrange changes of settings on analog lines and being a last resort for this
kind of situation. <br>
<br>
I do know however that this feature is implemented for example on Cisco IOS for
analog gateways, Audiocodes gateways and Patton gateways. <br>
<br>
Cisco IOS and Patton requires one to specify the frequencies and cadence of the
tone, Audiocodes provides an application that records the call progress tones
and then analyzes the recorded busy signal to be used as the disconnect signal.<br>
<br>
I used to work at Cisco TAC supporting H323 analog and digital gateways, and in
my experience the feature certainly saved the day in many cases after the
customer was frustrated in trying to find out what his/her provider implemented
on the line.<br>
<br>
My vote goes for it!<o:p></o:p></span></font></p>
