I upgraded freeswitch from git.
Nothing changed in the configuration!
Suddenly stopped working freetdm.
Why?

my configs:

freetdm.conf

[span zt pri]
name => pri
trunk_type => E1
group => e1group
b-channel => 1-15
d-channel => 16
b-channel => 17-31

wanpipe.conf

[defaults]
codec_ms => 20
wink_ms => 150
flash_ms => 750

freetdm.conf.xml

<configuration name="freetdm.conf" description="Freetdm Configuration">
<settings>
    <param name="debug" value="7"/>
</settings>
<libpri_spans>
    <span id="1" name="pri">
        <param name="node" value="network"/>
        <param name="switch" value="euroisdn"/>
        <param name="l1" value="alaw"/>
        <param name="dp" value="international"/>
        <param name="debug" value="all"/>
        <param name="dialplan" value="XML"/>
        <param name="context" value="default"/>
    </span>
    </libpri_spans>
</configuration>
