style='font-size:12.0pt'>Hello, </span></font></span><br>
<br>
<span class=postbody>I am having an issue whereby calls are being dropped
randomly. I have an ISDN 30 E1 line going into a Wildcard TE220 (4th Gen). My
Asterisk install is based on Trixbox 2.0. However, I have updated the source
code to the following. The Asterisk release is asterisk-1.2.20. Zaptel release
is zaptel-1.2.18. And libpri release is libpri-1.2.4. </span><br>
<br>
<span class=postbody>I have include an extract from the Asterisk log file below
that shows SIP/781 dropping a call when bridged to Zap/3-1. I have also
included my zaptel and zapata conf files. </span><br>
<br>
<span class=postbody>I have researched the various messages displayed in the
log file but couldn't see anything that would point definitively to why calls
are being dropped. </span><br>
<br>
<span class=postbody>Has anyone experienced anything similar or can anyone give
me a few ideas on where to start looking for the cause of the drop-outs? </span><br>
<br>
<span class=postbody>Many thanks.<o:p></o:p></span></p>
