BLF and DND

I am using the XML Scripts by Aastra for Trixbox CE. They set the DND feature at the PBX level I assume. Should I see the BLF light change for a user that is on DND?

I think hhmcpas wants to see on his phone's DEL, if the DND is active on the monitored phones.

I need the same possibility ^^

On Asterisk 1.4 branch, we can't "set" a hint.
On Asterisk 1.6 branch, I think we can set a hint in the dialplan.

you should ping philippe on this? I talked to him a few months ago about this and he was going to make this work for Asterisk 1.4 systems but since we are still on 1.2 it would do me no good.

This would require:

1. Asterisk to be patched with a back ported version of func_devstate.c which comes from 1.6 but is available for 1.4.
2. modifications to the DND module to set the devstate
3. modifications to the hints that get generated for an extension today, or a new hint to be created, to include the custom DND devstate status.
4. modifications to the Asterisk startup process to trigger something that will initialize the state of each phone upon Asterisk starting up since this is not retained.
5. writing the script or dialplan that will do (4) above

I think that is it. Then anyone subscribing to the BLF of what you generate above will get a response everytime DND is pressed for a phone.

Actually, I suppose you could try a hint with both devices.

exten => 101,hint,SIP/101&Custom:dnd101

Well as I have learned along time ago to get a project started someone has to offer up some money. I feel this is an important feature and Schmooze will put up $250.00 to get things started. Lets all rally behind here and see if we can get enough money raised to get this project done.

Philippe can you give us an idea on what it would cost to have all the completed?

timborino,
further testing indicates you are correct and the device states are kept in astdb. The system I was testing on was 1.4.19 and it shows the state as unavailable after restart even though the devices that subscribe to it are getting the proper state. So that would mean 4 and 5 above are not needed and thus there should be a bit less work involved in doing this.

I have not had anything to contribute however I have been watching the thread with interest.

This is a great community and when someone like yourself jumps in and starts figuring out how things work and trying new applications it is a pleasure to help with the process.

Best of luck to you on your application.

Take a look at the FreePBX 2.5 beta, I think the functionality you want is there.

Is the func_Devstate module already included when I perform the Trixbox upgrade instructions per the freePBX site or is this a module that I have to compile? I used the Trixbox upgrade tool but I am not really sure if the devstate module is working. Here's what I have done to test using Trixbox 2.6.1 and FreePBX 2.5 beta installed with the upgrade tool.

I have 2 extensions setup 100 and 104.

100 has a BLF button for 104. I put 104 on DND and the BLF light doesn't change. I did the USEDEVSTATE=true in the /etc/amportal.conf and reloaded asterisk.

Am I missing a step possibly?

Thanks again!

Thanks Philippe and all the others for the help along the way! I can't thank the community enough for the help you've provided! Here's my specs and solution to the problem

Specs:
Trixbox CE 2.6.1 (asterisk 1.4.20)
Aastra-xml-scripts installed
FreePBX 2.5 RC3 (Performed the upgrade per the FreePBX documentation)
Aastra 57i

Problem: When a extension was put on DND using the aastra-xml-scripts DND application for a 57i the other subscribed users had no BLF light notification that the ext was on DND. The BLF light simply showed "On Hook". The desired result is: When 104 is on DND then ext 100 should have a visual notification. Thanks to the func_devstate module and the FreePBX 2.5 features, this is now possible.

Solution:
Compile and install the func_devstate module for asterisk 1.4.20
Verify that the module is working per Philippe's instructions above
use *76 to put your phone in DND to verify that your BLF button on the subscribed station changes.
Find the Aastra_manage_DNDAasterisk(user,action) section and add the noted 4 lines to AastraAsterisk.php in the /var/www/html/aastra/include directory (look for the "#add the following 2 lines" comment in the following code to see what to add and where)

##################################################################################################
# Aastra_manage_dnd_Asterisk(user,action)
#
# This function reads and write the DND value in Asterisk Database.
#
# Parameters
# @user user extension
# @action action to be performed, change or anything
#

###################################################################################################
function Aastra_manage_dnd_Asterisk($user,$action)
{
# Connect to AGI
$as = new AGI_AsteriskManager();
$res = $as->connect();

# DND GET
$res = $as->Command('database get DND '.$user);
$line=split("\n", $res['data']);
$value=split(' ', $line[0]);
if($value[1]=='YES') $dnd=1;
if($dnd==0)
{
$value=split(' ', $line[1]);
if($value[1]=='YES') $dnd=1;
}

# Reverse DND if requested
if($action=='change')
{
# change DND status
if($dnd==0)
{
$res = $as->Command('database put DND '.$user.' YES');
##############################################################
#add the following 2 lines
##############################################################
$res = $as->Command('core set global DEVSTATE(Custom:DEVDND'.$user.') BUSY');
$res = $as->Command('core set global DEVSTATE(Custom:DND'.$user.') BUSY');
$dnd=1;
}
else
{
$res = $as->Command('database del DND '.$user);
###############################################################
#add the following 2 lines
###############################################################
$res = $as->Command('core set global DEVSTATE(Custom:DEVDND'.$user.') IDLE');
$res = $as->Command('core set global DEVSTATE(Custom:DND'.$user.') IDLE');
$dnd=0;
}
}

# Disconnect properly
$as->disconnect();

# Return DND
return($dnd);
}

This may not be the most elegant PHP code in the world. I am NOT a developer of any sort. So, if someone sees a better way to accomplish the same thing, please speak up. For now, I know one thing, It works...

Thanks again for the help.

I THINK that the $user string in this case is used to specify the extension. when the DND button is pressed it does this
http://ip.of.trix.box:80/aastra/asterisk/dnd.php?user=104
So, when extension 104 goes into DND it would play out like this
...('core set global DEVSTATE(Custom:DEVDND104) BUSY');

At least that's what I've pieced together...I think.

When I use the updated PHP and do a "show hints" i see this:

-= Registered Asterisk Dial Plan Hints =-
104@ext-local : SIP/104&Custom:DND10 State:InUse Watchers 1
100@ext-local : SIP/100&Custom:DND10 State:Idle Watchers 0
*21104@ext-findmefollow : Custom:FOLLOWME104 State:Idle Watchers 0
*21100@ext-findmefollow : Custom:FOLLOWME100 State:Idle Watchers 0
*76104@ext-dnd-hints : Custom:DEVDND104 State:Busy Watchers 0
*76100@ext-dnd-hints : Custom:DEVDND100 State:Idle Watchers 0

and when I UN-DND I get:
-= Registered Asterisk Dial Plan Hints =-
104@ext-local : SIP/104&Custom:DND10 State:Idle Watchers 1
100@ext-local : SIP/100&Custom:DND10 State:Idle Watchers 0
*21104@ext-findmefollow : Custom:FOLLOWME104 State:Idle Watchers 0
*21100@ext-findmefollow : Custom:FOLLOWME100 State:Idle Watchers 0
*76104@ext-dnd-hints : Custom:DEVDND104 State:Idle Watchers 0
*76100@ext-dnd-hints : Custom:DEVDND100 State:Idle Watchers 0

Same thing as when I *76

Sound right?
