Hello,
We are using freeswitch with libpri from last 7 years. It was running well without any issue. Currently we decided to move our server to latest hardware. Installation went perfect and freeswitch was up and running. But when i tried to load mod_freetdm. Freeswitch throws a kernal opps and it loaded successfully but my signal status showing down. attaching my configuration. I am using sangoma A104DE.. Attaching my configuration below 1) Freetdm.conf [span wanpipe wp1] trunk_type => e1 group=1 b-channel => 1:1-15 b-channel => 1:17-31 d-channel => 1:16 2) Freetdm.conf.xml <configuration name="freetdm.conf" description="Freetdm Configuration"> <settings> <param name="debug" value="0"/> <!--<param name="hold-music" value="$${moh_uri}"/>--> <!--<param name="enable-analog-option" value="call-swap"/>--> <!--<param name="enable-analog-option" value="3-way"/>--> <param name="crash-on-assert" value="no"/> </settings> <config_profiles> <profile name="my_pri_te_1"> <param name="switchtype" value="euroisdn" /> <param name="interface" value="cpe"/> </profile> </config_profiles> <libpri_spans> <span name="wp1" cfgprofile="my_pri_te_1"> <param name="dialplan" value="XML"/> <param name="context" value="default"/> <param name="node" value="cpe"/> <param name="switch" value="euroisdn"/> </span> </libpri_spans> <analog_spans> </analog_spans> </configuration> Please help me. Since same configuration is running over my other server without any issue on same os.
