<p class=MsoNormal>Hi,<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>Although zonedata.c contains ITU E.180 recommendations for
Turkey, we are still experiencing unrecognized hangups from Turk Telekom
PSTN lines when callers hangup.<br>
<br>
Turk Telekom does *not* provide supervised disconnects on analog PSTN, and the
tone we receive we when caller hangs up is similar to busy, with three short
beeps, followed by one long beep, which keeps repeating. We've tried
busydetect, polarityswitch, etc. with no success.<br>
<br>
As it stands, asterisk using dahdi (with Digium TDM410p) does not work in
Turkey. Can offer small bounty for any developer wishing to solve this issue.<o:p></o:p></p>
<p class=MsoNormal><o:p> </o:p></p>
<p class=MsoNormal>The technology we have used shown below;<o:p></o:p></p>
<p class=MsoNormal>Asterisk 1.6.2.8<o:p></o:p></p>
<p class=MsoNormal>Libpri 1.4.11.1<o:p></o:p></p>
<p class=MsoNormal>Dahdi 2.3.0<o:p></o:p></p>
<p class=MsoNormal>Ubuntu Server 9.10<o:p></o:p></p>
