Dear All,
I am a starter on Freeswitch although I have telecoms experience for a long time
I am trying to set-up a Freeswitch server with a Digium TE110P ISDN PrI E1 card.
I have installed DAHDI Drivres and the card is discovered OK.
I have also installed the libpri library and activated mod_freetdm. When I run the freeswitch I can see that my span is defined when I connect disconnect the cable I recieve alarms as below

The problem I have is no matter what I do signalling_status is always DOWN.
freeswitch@voip.cybetech.com> ftdm list
+OKspan: 1 (GSMChannelBank)
type: isdn
physical_status: ok
signaling_status: DOWN
chan_count: 31
dialplan: XML
context: public
dial_regex:
fail_dial_regex:
hold_music:
analog_options: none
I have changed various settings in the configuration files but there is no change. my conf files are as follows:
/etc/dahdi/system.conf:
span=1,0,0,ccs,hdb3
bchan=1-15,17-31
dchan=16
loadzone = us
defaultzone = us
freetdm.conf:
general
cpu_monitor => no
cpu_monitoring_interval => 1000
cpu_set_alarm_threshold => 80
cpu_reset_alarm_threshold => 70
cpu_alarm_action => warn
debugdtmf_directory=/usr/local/freeswitch/log/
span zt GSMChannelBank
trunk_type => E1
b-channel => 1-15
d-channel => 16
b-channel => 17-31
freetdm.conf.xml:
<configuration name="freetdm.conf" description="FreeTDM Configuration">
<settings>
<param name="debug" value="0"/>
</settings>
<libpri_spans>
<span name="GSMChannelBank">
<param name="switch" value="euroisdn"/>
<param name="mode" value="net"/>
<param name="debug" value="none"/>
<param name="dialplan" value="XML"/>
<param name="context" value="public"/>
</span>
</libpri_spans>
</configuration>
I will appreciate if anyone can advise where I shall look for the solution.
