<br>ISDN 30 E1 line going into a Wildcard TE220 (4th Gen). My Asterisk<br>install is based on Trixbox 2.0. However, I have updated the source code<br>to the following. The Asterisk release is asterisk-1.2.20. Zaptel<br>release is
zaptel-1.2.18. And libpri release is libpri-1.2.4.<br><br>I have include an extract from the Asterisk log file below that shows<br>SIP/781 dropping a call when bridged to Zap/3-1. I have also included my<br>zaptel and zapata conf files.
<br><br>I have researched the various messages displayed in the log file but<br>couldn't see anything that would point definitively to why calls are<br>being dropped.<br><br>Has anyone experienced anything similar or can anyone give me a few
<br>ideas on where to start looking for the cause of the drop-outs?<br><br>Many thanks.<br><br><br><br>/var/log/asterisk/full:<br><br><br><br>Channel 0/3, span 1 got hangup request, cause 16<br>Sep 18 16:01:03 DEBUG[32377]
