When dialing out, Freeswitch/Openzap is not detecting that an analog FXO channel is disconnected and tries dialing out on the channel anyway. No error is reported. The call doesn’t timeout until a minute later. Shouldn’t Freeswitch/Openzap skip over a disconnected channel to the next connected channel?
I have configured a Sangoma A200 FXO card as a FXO span.
[span wanpipe FXO]
name => PSTN Line 1
number => 4253491059
fxo-channel => 2:3
name => PSTN Line 2
number => 4253491058
fxo-channel => 2:4
The wanpipe driver does detect and report when a CO line is connected or disconnected (in /var/log/messages), and Freeswitch/Openzap gets an event as reported in the log.
/var/log/messages: Feb 25 15:23:10 roberth-c53 kernel: wanpipe2: Module 3: FXO Line is disconnected!
FS_CLI: 2010-02-25 15:23:10.711604 [DEBUG] ozmod_analog.c:788 EVENT [ALARM_TRAP][3:1] STATE [DOWN]

I have the dialplan configured to use the next available port in the FXO span (there will be more than 2 channels later).
<extension name="OutgoingFXO">
<condition field="destination_number" expression="^7(\d+)$">
<action application="bridge" data="openzap/FXO/a/$1"/>
</condition>
</extension>
Here is a portion of the log when that shows dialing out on a disconnected analog FXO channel.
