10 Sockets in /var/run/screen/S-root.

Step 19 : WEBRTC Configuration

Follow the below steps to configure webrtc, Letencrypt SSL certificate and Viciphone webrtc webphone.

• Now you have your own domain and pointed to your server
• Try to access your server via domain http://xyz.ddns.net/

Step 20 :  Free SSL Certificate from Letsencrypt

LetsEncrypt is a Certificate Authority (CA) that provides free certificates for Transport Layer Security (TLS) encryption, thereby enabling encrypted HTTPS on web servers. It simplifies the process of creation, validation, signing, installation, and renewal of certificates by providing a software client that automates most of the steps—Certbot.

To generate the letsencrypt SSL certificate follow below steps.

Step 20.1 :  Install Certbot and Dependicies

yum install certbot python2-certbot-apache mod_ssl

Step 20.2 :  certbot command to generate SSL certificate

certbot certonly --w /var/www/html -d 24ithub.com --register-unsafely-without-email

<note: replace 24ithub.com with your domain>
<enter 3 for webroot location.
How would you like to authenticate with the ACME CA?
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
1: Apache Web Server plugin (apache)
2: Spin up a temporary webserver (standalone)
3: Place files in webroot directory (webroot)
- - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - - -
Select the appropriate number [1-3] then [enter] (press 'c' to cancel): 3

• Once the process is sucessfull ,you will get the sucessful message and the certificates and key will be save in below mentioned folder
• note: enter you domain after /live folder

cd /etc/letsencrypt/live/24ithub.com/
ls
cert.pem chain.pem fullchain.pem privkey.pem README

Step 21 : update ssl certificate in ssl.conf

You need to point your new ssl certificate and key path in the ssl.conf so that your server will be accessed via new Letsencrypt  certificates.

edit vi /etc/httd/conf.d/ssl.conf

search the below lines and update with your certificate as show below
SSLCertificateFile
SSLCertificateKeyFile

SSLCertificateChainFile 

SSLCertificateFile /etc/letsencrypt/live/24ithub.com/cert.pem
SSLCertificateKeyFile /etc/letsencrypt/live/24ithub.com/privkey.pem
SSLCertificateChainFile /etc/letsencrypt/live/24ithub.com/fullchain.pem

restart httpd service to update the changes

systemctl restart httpd

Step 22 : Check your SSL 

check your ssl using the website https://www.sslshopper.com/ssl-checker.html

Also access you dialer in  a browser and make sure it is accessible via https and without any ssl error.

if Yes you are good to go next steps.

Step 23 : Redirect All HTTP request to HTTPS request

we need to force the dialer access only via https , in order to avoid agents login to dialer via http which leads to failure of webrtc support.

edit httpd.conf
vi /etc/httpd/conf/httpd.conf

add the below entry after the last line

replace 24ithub.com with your domain.

<VirtualHost *:80>
    ServerName 24ithub.com
    DocumentRoot /var/www/html
    ErrorLog /var/www/error.log
    CustomLog /var/www/requests.log combined
RewriteEngine on
RewriteCond %{SERVER_NAME} =24ithub.com
RewriteRule ^ https://%{SERVER_NAME}%{REQUEST_URI} [END,NE,R=permanent]
</VirtualHost>

restart the httpd service

systemctl restart httpd

Now access your dialer with http://domain/  it should auto redirect to https://domain.

Step 24 : updating Vicidial Recordings link with https

By default the vicidial recordings links are update with http extension in DB,

in order to update the recording link to https extension you need edit your cronjob which you done in step 12 .

just add --HTTPS label in  AST_CRON_audio_2_compress.pl followed my --MP3 as shown below

/usr/share/astguiclient/AST_CRON_audio_2_compress.pl --MP3 --HTTPS

Step 25 : Asterisk Settings to enable webrtc

in order to asterisk support webrtc you need to edit below files

1. /etc/asterisk/http.conf

2. /etc/asterisk/modules.conf

3. /etc/asterisk/rtp.conf

4./etc/asterisk/sip.conf

vi /etc/asterisk/http.conf

and or enable below settings

enabled=yes
bindaddr=0.0.0.0
bindport=8088
tlsenable=yes
tlsbindaddr=0.0.0.0:8089
tlscertfile=/etc/letsencrypt/live/24ithub.com/cert.pem
tlsprivatekey=/etc/letsencrypt/live/24ithub.com/privkey.pem

NOTE: replace 24ithub.com with your domain name

vi /etc/asterisk/modules.conf

vi /etc/asterisk/rtp.conf

rtpstart=10000
rtpend=20000
icesupport=yes
stunaddr=stun.counterpath.com:3478

vi /etc/asterisk/res_stun_monitor.conf

stunaddr=stun.counterpath.com:3478
stunrefresh = 30

go to asterisk cli ,reload once and check stun updates similar like below

centos-s-4vcpu-8gb-intel-nyc1-01*CLI> stun show status
Hostname                  Port  Period  Retries  Status  ExternAddr       ExternPort

centos-s-4vcpu-8gb-intel-nyc1-01*CLI>

vi /etc/asterisk/sip.conf

update below entry

realm=your-domain or publicip
externaddr=your-publicip

Step 26 : Downloading the Viciphone 

you can download the official viciphone or enhanced version from below links, i prefer the enhanced version.

official link : https://viciphone.com  

githublink : https://github.com/vicimikec/ViciPhone.git

enhanced link : https://github.com/ccabrerar/ViciPhone.git

• download the file to a temp directory

cd /var/tmp
git clone https://github.com/ccabrerar/ViciPhone.git

• copy the file to vicidial agc folder and provide permission

cd /var/tmp
cp -r ViciPhone /var/www/html/agc/viciphone
chmod -R 755 /var/www/html/agc/viciphone

Step 27 : Vicidial Settings to Support Webrtc

• Set webphone as default phone .

ADMIN > SYSTEM SETTINGS > Default Webphone: 1

• Enter the webphone url

ADMIN > SYSTEM SETTINGS > Webphone URL:  

Webphone URL: viciphone/viciphone.php

• Set the websocket URL

ADMIN > SERVERS > Modify > Web Socket URL: 

wss://striker24x7.ddns.net:8089/ws

Step 28 : Vicidial webrtc TEMPLATE

Now we need to create webrtc sip template which we will assign to each phone created in vicidial.

Go to Admin -> Templates

copy paste the below settings, make to point to your ssl certificate path

type=friend
host=dynamic
encryption=yes
avpf=yes
icesupport=yes
directmedia=no
transport=wss
force_avp=yes
dtlsenable=yes
dtlsverify=no
dtlscertfile=/etc/letsencrypt/live/striker24x7.ddns.net/cert.pem
dtlsprivatekey=/etc/letsencrypt/live/striker24x7.ddns.net/privkey.pem
dtlssetup=actpass
rtcp_mux=yes

Step 29 : Vicidial Phones as Webphone

Goto ADMIN > PHONES 

either add new phone or modify your existing phone and enable the below settings

Set As Webphone:  Y

Webphone Dialpad:Y

Webphone Auto-Answer: Y

Webphone Dialbox: Y

Webphone Mute: Y

Webphone Volume:Y

at Last line under TEMPLATE ID select the webrtc template created in step 27

 

Step 30 : Final workaround : delay the webphone login call

By default as soon you login as agent, the vicidial will initiate the first login call and play the message "you are the only person in conference"

You might miss this sound or call because of browser loading speed and time the webphone registring time.

To avoid this we will delay the call by 10 sec.

Follow the steps 

cd /var/www/html/agc
cp options-example.php options.php

Now edit the options.php file and set 10 for $webphone_call_seconds  

cd /var/www/html/agc
vi +64 /var/www/html/agc/options.php

search for below line and enter 10
$webphone_call_seconds  = '10';

Step 31 : reboot

use your Favourite browser to access your dialer, 

i prefer firefox as my favourite .

URL: https://FQDN/agc/admin.php

you should be now able to login as agent with webphone/webrtc as shown below

Note : while logging in , the browser will ask permission to use MIC , Press ALLOW

Finally you can see your agent panel with Webphone.
