<br>
Hello,<br>
<br>
<br>
I found, that FS doesn&#39;t maintain D-Channel&#39;s state correctly.<br>
<br>
I have a PRI with disabled layer 2 and 3 on TDM side. When FS starts up<br>
I get this on console:<br>
<br>
<br>

<br>
So TDM side tells FS that the link is down:<br>
<br>
but when I check d-channel&#39;s state FS tells me that it is UP:<br>
<br>
freeswitch@ippbx-prod-node0&gt; oz dump 1 16<br>
API CALL [oz(dump 1 16)] output:<br>
span_id: 1<br>
chan_id: 16<br>
physical_span_id: 1<br>
physical_chan_id: 16<br>
type: DQ921<br>
state: UP<br>
last_state: DOWN<br>
cid_date:<br>
cid_name:<br>
cid_num:<br>
ani:<br>
aniII:<br>
dnis:<br>
rdnis:<br>
cause: NONE<br>
<br>
When I do an outbound call FS throws no error or warning that the link<br>
isn&#39;t up and gives the call a try.<br>
<br>
<br>
