[Freeswitch-users] Freeswitch/Openzap dials out on disconnected FXOline

[Robert Hadley]

Using a Sangoma A200 FXO card, is there any way for Freeswitch to
automatically detect a disconnected CO line and use another FXO channel?

 

Thanks,

Robert

FXOline

 

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]

 

/var/log/messages: Feb 25 15:23:44 roberth-c53 kernel: wanpipe2: Module 4:
FXO Line is connected!

FS_CLI: 2010-02-25 15:23:44.901979 [DEBUG] ozmod_analog.c:788 EVENT
[ALARM_CLEAR][3:2] 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.
