How to – Remove the water drop/bloop sound from ViciDial -As we all know that in Asterisk new version, Asterisk is not going to be using meetMe anymore and they have set it to “End of life” so it will no longer get any updates.

So what does this mean for Vicidial which uses MeetMe channels for all its sounds and communications?

Well, there is another module called app confbridge which we can use and that can also handle these jobs and actually can do so much better than app meetme.

App Confbridge has capabilities for some more advanced features over time I’m sure. Ok so let’s start with the main issue a lot of people are going to have.

They are really scared more than anything, is confbridge needs at least Asterisk 16 to work so our first step is going to be to update Asterisk from 13 to 16.

The good news is once you do this, you can remove the water drop sound from the customer side of the calls you make so they no longer know you are calling from a call center and hangup before you even get a chance to say hi.

Before getting to step 1, make sure you are at the latest SVN which at the time of this article is 3636 by following this article.

Time needed: 2 minutes

Step 1 – Upgrade to Asterisk 16
So lets go ahead and install Asterisk 16 by following the steps below:

cd /usr/src/
wget http://download.vicidial.com/beta-apps/asterisk-16.17.0-vici.tar.gz
tar -xzvf asterisk-16.17.0-vici.tar.gz
cd asterisk-16.17.0-vici
./configure –libdir=/usr/lib64 –with-pjproject-bundled –with-jansson-bundled
rm -rf menuselect.makeopts
make menuselect*
**** Go down one to applications and hit enter, go down until you find the “meetme” app and press space bar, then hit “X” ****
make && make install
make uninstall
make install
We had to fix the Asterisk 16 install over Asterisk 13 by running “make uninstall” and then reinstalling as shown here:

Fixing Asterisk 16 install

Now we need to stop the current Asterisk 13 from running and start back up the new Asterisk 16.

asterisk -r
core restart now
/usr/share/astguiclient/start_asterisk_boot.pl
asterisk -r (make sure the version you see is 16)
Step 2 – Add new confbridge extensions – How to Remove the water drop sound from ViciDial
We need to edit extensions.conf and add some new conferences for confbridge to use so lets start by going into the asterisk directory:
cd /etc/asterisk
nano extensions.conf
paste the following at the bottom:

; -------------------------- ;
ConfBridge Extensions

exten => _99600XXX,2,Hangup()
exten => _55559600XXX,1,ConfKick(${EXTEN:4},all)
exten => _55559600XXX,2,Hangup()

Save and exit
Step 3 – Add additional code for confbridge to work correctly
We have to edit a couple files so first lets do:
nano /etc/asterisk/confbridge.conf and paste this at the bottom:
#include confbridge-vicidial.conf
Now create a new file called confbridge-vicidial.conf and add the following lines:

Step 4 – Add ConfBridge Conferences to Database
Go into mysql and add the conferences to the vicidial_confbridges table by pasting the following commands:
mysql -A asterisk
INSERT INTO `vicidial_confbridges` VALUES

Update the IP to your server IP by running the following command:
/usr/share/astguiclient/ADMIN_update_server_ip.pl –old-server_ip=10.10.10.17 (Click Enter for Y)

Next enter your server IP and press enter twice to chaneg it in the DB as show below:

Update Server IP
Step 5 – Code changes to ViciDial files -How to Remove the water drop sound from ViciDial
There are some files now that have to be patched in order to include the changes needed for confbrides to work. They are in the “extras/ConfBridge/” directory of the svn/trunk codebase.
Lets copy the files over to where they are needed, this will depend on if you are using a single server or a cluster to where the files go. Here is a list of where they go:
Dialers:
/usr/share/astguiclient/ –
– ADMIN_keepalive_ALL.pl.diff
– ADMIN_update_server_ip.pl.diff
– AST_DB_optimize.pl.diff
– AST_reset_mysql_vars.pl.diff
– AST_VDremote_agents.pl.diff
– AST_conf_update_screen.pl
Webservers:
/srv/www/htdocs/agc/ –
– vicidial.php.diff
– vdc_db_query.php.diff
– manager_send.php.diff
/srv/www/htdocs/vicidial/ –
– non_agent_api.php.diff
You can copy and paste the entire code below to get it all done
cd /usr/src/astguiclient/trunk/extras/ConfBridge/
cp * /usr/share/astguiclient/
cd /usr/share/astguiclient/
mv manager_send.php.diff vdc_db_query.php.diff vicidial.php.diff /var/www/html/agc/
patch -p0 < ADMIN_keepalive_ALL.pl.diff
patch -p0 < ADMIN_update_server_ip.pl.diff
patch -p0 < AST_DB_optimize.pl.diff
chmod +x AST_conf_update_screen.pl
patch -p0 < AST_reset_mysql_vars.pl.diff
cd /var/www/html/agc/
patch -p0 < manager_send.php.diff
patch -p0 < vdc_db_query.php.diff
patch -p0 < vicidial.php.diff
Step 6 – Add the confbridge keepalive and turn off the conf_update keepalive in crontab
A new screen session has been added called ‘AST_conf_update_screen.pl’. This screen session replaces both the AST_conf_update.pl and AST_conf_update_3way.pl scripts.
It checks both MeetMe and ConfBridge conferences for unnecessary channels and removes them. For instance if an agent does a Leave 3way and a few minutes later one of the remaining channels hangs up. This script will remove the remaining channel and free the conference for use by Vicidial.
This screen session is optional for use with MeetMe but is required to be used with ConfBridge.

Add C to VARactive_keepalives
To enable this screen session you need to add a ‘C’ to the ‘VARactive_keepalives’ variable in the ‘/etc/astguiclient.conf’ on your dialers, and comment out the following line from your crontab:

### updater for conference validator
#* * * * * /usr/share/astguiclient/AST_conf_update.pl

You can configure the refresh interval for how often the screen session checks for unnecessary channels by changing “Conf Update Interval” in Admin -> Servers.
Step 7- Make the needed changes in ViciDial GUI
Login to the ViciDial Admin GUI and go to Admin > Servers and click on the server(s) that are dialers and change the conferencing engine to “CONFBRIDGE” as shown below:

Change conferencing Engine to CONFBRIDGE
That’s a lot to get through but now that its done your customers will no longer hear the “Water drop” or “bloop” sound that they do now and you’re ready for the future of Asterisk now that app meetme has been deprecated. That’s it for now, you’re all done. Hopefully this helps those of you who are a little intimidated to try the change
