Hi Guys.

Current setup is a FS box with a Digium TE122 installed, with DAHDI kernel drivers and using FreeTDM with a libpri span...

== autoload_configs/freetdm.conf.xml ==

<configuration name="freetdm.conf" description="FreeTDM Configuration">
    <settings>
        <param name="debug" value="0"/>
        <param name="sip_headers" value="true"/>
    </settings>
    <libpri_spans>
        <span name="ISDN">
            <param name="mode" value="user"/>
            <param name="dialect" value="q931"/>
            <param name="dialplan" value="XML"/>
            <param name="context" value="public"/>
        </span>
    </libpri_spans>
</configuration>

== freetdm.conf ==

[general]
cpu_monitor => yes
cpu_monitoring_interval => 1000
cpu_set_alarm_threshold => 80
cpu_reset_alarm_threshold => 70
cpu_alarm_action => warn

[span zt ISDN]
trunk_type => E1
b-channel => 1-15
d-channel => 16
b-channel => 17-21

== zt.conf ==
[defaults]
codec_ms => 20
wink_ms => 150
flash_ms => 750
echo_cancel_level => 128
rxgain => 0.0
txgain => 0.0

== /etc/dahdi/system.conf ==
span=1,1,0,ccs,hdb3,crc4
# termtype: te
bchan=1-15,17-31
dchan=16
echocanceller=mg2,1-15,17-31
# Global data
loadzone    = au
defaultzone = au


=========
And finally some logs from two calls, a successful one, and a failed one...

If anyone could offer any suggestions as to what I can do to answer every incoming call into the box that would very appreciated. Of course if I need to provide more information I am willing to, and any suggestions for settings that need changing to test out will also be great.

Thank you in advance
Matt
