Vicidial install on Ubuntu 14.04

Updated: March-25-2019

Note: Below steps only cover standalone server installation on Ubuntu 14.04. 

I am using Digitalocean VPC. Installation should be similar in AWS EC2 instances.

Make sure to open 8088,8089,80,443 TCP and 10000 -20000 UDP ports Open in your firewall..

Standard Packages:

sudo apt-get install build-essential

apt-get install linux-headers-`uname -r`

apt-get install subversion libjansson-dev sqlite autoconf automake  libxml2-dev libncurses5-dev -y

sudo add-apt-repository ppa:ondrej/php

#Press ENTER

sudo apt-key adv --keyserver keyserver.ubuntu.com --recv-keys E5267A6C 

#Press ENTER

sudo apt update

sudo apt-get install apache2 apache2-bin apache2-data libapache2-mod-php5.6 php5.6 php5.6-cli php5.6-common php5.6-json php5.6-mysql php5.6-readline sox lame screen libnet-telnet-perl php5.6-mysqli  -y

apt-get install libasterisk-agi-perl

apt-get install mysql-server

apt-get install libelf-dev

apt-get install autogen libtool shtool

Special package for ASTblind and ASTloop(ip_relay need this package)

apt-get install libc6-i386

#This Setup is painful, but you need to do it.(will try to add the packages)

[email protected]:~# cpan

There seems to be running another CPAN process (pid 9731). Contacting...
Other job is running.
Shall I try to run in downgraded mode? (Y/n) [y] 
Running in downgraded mode (experimental).

All Set now. Now, You can configure web interface and logins.
Vicidial Admin login :
user: 6666
Pass: 1234
Continue On to the Initial Setup
#Add Secure Password for admin and SIP
#Give Super admin access to 6666 user
users —> 6666 –> Change all 0 to 1 in Interface Options.
#Enable WebRTC from GUI and Download PBXWebPhone
cd /var/www/html/agc/
git clone https://github.com/chornyitaras/PBXWebPhone.git
# Add Web Socket URL to Server in Server settings from 6666(Admin login).

Replace j.thoutam.com with your domain.

# Goto system settings and Add WebPhone URL path

#Goto Templates --> SIP_generic and add below content to template.

;Replace j.thoutam.com with your domain.

#Goto to Phones --> Select cc100 --> Set As a WebPhone --> Y 

And Set Template ID: SIP_Generic

Wait for few minutes to Generate config..

#Next steps
1. Create Campaign
2. Create SIP Trunk
3. Create Dialplan
4. Upload Leads
5. Register Users to SopftPhone
6. Create Agents/users
Note: If WebRTC enable you don’t need softphone anymore.
And Enjoy…
Note: if you building the server for more than 30+ agents, I recommend to use bare metal servers than VPC. 
Please let me know if you have any issues.

Media parameter in SIP

m=audio 12548 RTP/AVP 0 8 101

It’s a field from SDP protocol, describing parameters of media (“m” is for “media”). Next, the type of media is “audio”, not video, for example. (m=audio). 12548 is a port address for streaming media. “RTP/AVP” means “RTP Audio/Video
Profile” and representing one of RTP profiles, which are coded by 0, 8 and 101. 0 is PCMU 8000 Hz, 8 is PCMA 8000 Hz, and 101 is payload type for DTMF digits sending.

Install OpenSIPs

Install OpenSIPs

OpenSIPS is a multi-functional, multi-purpose signaling SIP server used by carriers, telecoms or ITSPs for solutions like Class4/5 Residential Platforms, Trunking / Wholesale, Enterprise / Virtual PBX Solutions, Session Border Controllers, Application Servers, Front-End Load Balancers, IMS Platforms, Call Centers, and many others…

Platfrom : Ubuntu 14.04 +

Let’s Begin…

apt-get install build-essential openssl bison flex
apt-get install perl libdbi-perl libdbd-mysql-perl libdbd-pg-perl libfrontier-rpc-perl libterm-readline-gnu-perl libberkeleydb-perl ncurses-dev
apt-get install mysql-server libmysqlclient-dev
wget http://opensips.org/pub/opensips/latest/opensips-2.3.0.tar.gz
tar -xvf opensips-2.3.0.tar.gz
cd opensips-2.3.0/
make all
make install 
mkdir /var/run/opensips
cd packaging/debian/
cp opensips.default /etc/default/opensips
cp opensips.init /etc/init.d/opensips
chmod +x /etc/init.d/opensips
useradd opensips
update-rc.d opensips defaults 99
vim /etc/default/opensips
Here you need to replace the 'RUN_OpenSIPS' to 'Yes'. You can also change the user and group and name that you wish to use for the Opensips services and also change the shared memory to minimum 128 which is recommended for the OpenSIPS server.


we also need to update the daemon on OpenSIP and change it location in its startup script and update its state from ‘off’ to ‘on’ and then close the file after making changes.
