Unlocking Workflow Efficiency

At the heart of CyburDial’s automation system is its robust workflow engine. This engine empowers call centers to create customized workflows tailored to their specific needs.

3. Data Validation and Entry: Say goodbye to manual data entry errors. CyburDial’s automation system validates and enters customer information accurately into databases, reducing the risk of data discrepancies.
4. Scripted Interactions: Agents are guided through scripted interactions, ensuring consistency in messaging and compliance with company policies and regulations.
5. Real-time Analytics: The system provides real-time insights into workflow performance, allowing call centers to make data-driven decisions for continuous improvement.

Enhancing the Customer Experience

Automation isn’t just about improving operational efficiency; it’s also about elevating the customer experience. With CyburDial’s automation system, call centers can:

• Reduce wait times: Calls are routed swiftly to available agents, minimizing customer frustration.
• Provide personalized service: Automation enables agents to access customer data and history instantly, enabling personalized interactions.
• Resolve issues faster: Automated workflows streamline issue resolution, leading to higher first-call resolution rates.
• Deliver consistent service: Scripted interactions and automated processes ensure that customers receive consistent service quality.
• Anticipate customer needs: Data-driven insights from automated processes enable call centers to predict and fulfill customer needs proactively.

CyburDial: A Partner for the Future

CyburDial’s automation system is not just a technological advancement; it’s a strategic partner for call centers looking to thrive in an increasingly competitive landscape. By harnessing the power of full automation and customizable workflows, call centers can transform their operations, reduce costs, improve customer satisfaction, and stay ahead of industry trends.

Unlocking Efficiency: How CyburDial Is Revolutionizing Call Centers and Solving Common Pain Points

—

In the world of call centers, efficiency is the name of the game. Whether you’re managing customer support, telemarketing, or tech assistance, you know that even the smallest hiccup can cause headaches. But fear not, because CyburDial is here to change the game and transform your call center operations. In this article, we’ll explore some of the most common pain points in call centers and how CyburDial’s innovative approach is saving businesses both time and money.

Common Call Center Pain Points

1. High Operational Costs: Traditional pricing models for dialer solutions often involve per-seat charges. This means that as your call center grows, your costs skyrocket. Managing expenses becomes a complex puzzle that hinders your scalability.
2. Inefficient Dialing: Wasted time on endless calls that lead to dead ends is a call center’s nightmare. Low connection rates can result in agents twiddling their thumbs instead of engaging with customers.
3. Compliance Challenges: Staying compliant with ever-evolving regulations in the call center industry can be a daunting task. The consequences of non-compliance can be severe, leading to hefty fines and tarnished reputations.
4. Complex Pricing Structures: Trying to decipher convoluted pricing structures can give anyone a headache. The per-minute, per-seat, and per-feature pricing makes budgeting an administrative nightmare.
5. Scalability Concerns: As your business grows, adding new agents to your call center should be a breeze. But with traditional solutions, it often turns into a logistical challenge, and scaling can become a costly endeavor.

The Per-Seat Model’s Pain Points

For years, call centers have grappled with the per-seat model. In this system, businesses pay for each agent, which can lead to hefty monthly expenses. As you can imagine, this approach presents several challenges:

1. Costly Overheads: The per-seat model can quickly become expensive as your call center expands. Paying for each agent can strain your budget and limit scalability.
2. Stifled Growth: The fear of increased costs can hinder call center growth. This means missed opportunities and slower response times during peak periods.
3. Complex Pricing Structures: Managing pricing for numerous seats can be administratively burdensome and confusing.
4. Limited Efficiency: Conventional dialing solutions might struggle to achieve high connection rates, leading to wasted time and resources.

But what if we told you there’s a better way?

Enter CyburDial: Redefining Call Center Operations

Whether you’re reaching out to potential customers or managing existing client relationships, the way you connect can make or break your success. This is where Dialer.One steps in, offering innovative AI technology to enhance connection rates and streamline communication processes, ultimately saving businesses time and money.

AI Numbers for Local Presence

Dialer.One understands the importance of establishing a local presence when engaging with customers. To address this, they employ AI numbers that automatically assign local area codes to your outgoing calls.

But Dialer.One doesn’t stop there. They also manage DID (Direct Inward Dialing) numbers efficiently. This includes adding new DIDs to the system and removing old ones marked as potential scam or nuisance callers.

AI Answering Machine Detection

Wasting time leaving voicemails on answering machines is not an efficient use of resources. Dialer.One’s AI technology elevates answering machine detection levels to an impressive 97%. This means your agents will spend less time talking to voicemail systems and more time engaging in meaningful conversations with potential customers.

The result? Increased efficiency, improved agent morale, and significant time and cost savings.

DNC and TCPA Litigator Filtering

Compliance with regulations such as the Do Not Call (DNC) list and the Telephone Consumer Protection Act (TCPA) is paramount. Non-compliance can lead to costly lawsuits and tarnished reputations. Dialer.One offers a solution by implementing DNC and TCPA litigator filtering.

By cross-referencing your call list with these databases, Dialer.One ensures you avoid contacting individuals who have requested not to be called or are known litigators. This proactive approach not only keeps your business in compliance but also shields you from potential legal troubles.

STIR/SHAKEN Compliance

As the regulatory landscape evolves, staying up-to-date is essential. Dialer.One stays ahead of the curve by adapting to new dialing laws, including STIR/SHAKEN. These protocols are designed to verify the authenticity of caller IDs, reducing the prevalence of spam and fraudulent calls.

By integrating these technologies, Dialer.One helps boost your business’s productivity and performance while maintaining compliance with the latest industry standards.

How to – use Firewalld via command line

This short post is just going to briefly go over the more common commands you need in order to manage firewalld and make sure you keep your servers safe. This firewall works in conjunction with the dynamic portal for ViciDial as well as the built in whitelist initially named ViciWhite in the IP list area in Admin.

Systemctl and Firewalld

Enable firewalld

This makes sure that firewalld will be started automatically with the server.

systemctl enable firewalld

Start firewalld

After the firewalld service is enabled, you’ll need to start it manually the first time. This is how you would manually start firewalld if it were not already running.

systemctl start firewalld

Stop firewalld

When troubleshooting rules and connection issues, you may need to stop the fireawlld service momentarily. You can stop the service with the following command.

systemctl stop firewalld

Restart firewalld

If for some reason, you need to restart the service, you can do that with the systemctl restart command.

systemctl restart firewalld

Firewalld status

Checking the status of the service gives us the most meaningful and informative output. Here you can see whether the service is enabled, running, failed, or anything else.

systemctl status firewalld

In this example output, you can see that the service is enabled, active, and running on the server. If it were not running or in a failed state, this would be displayed.

[root@alma ~]# systemctl status firewalld
● firewalld.service - firewalld - dynamic firewall daemon
Loaded: loaded (/usr/lib/systemd/system/firewalld.service; enabled; vendor preset: enabled)
Active: active (running) since Tue 2019-01-22 22:50:32 EST; 1h 0min ago
Main PID: 808 (firewalld)
CGroup: /system.slice/firewalld.service
└─808 /usr/bin/python -Es /usr/sbin/firewalld --nofork --nopid

Managing Firewalld and Configuring Rules

Now that we have firewalld running, we can get down to set the configuration. We can open ports, allow services, whitelist IPs for access, and more. In all of these examples, we include the –permanent flag. This is important to make sure a rule is saved even after you restart firewalld, or reboot the server. Once you’re done adding new rules, you need to reload the firewall to make the new rules active.

Add a Port for TCP or UDP

You do have to specify TCP or UDP and to open a port for both. You will need to add rules for each protocol.

firewall-cmd --permanent --add-port=22/TCP
firewall-cmd --permanent --add-port=53/UDP

Remove a Port for TCP or UDP

Using a slight variation on the above structure, you can remove a currently open port, effectively closing off that port.

firewall-cmd --permanent --remove-port=444/tcp

Add a Service

These services assume the default ports configured within the /etc/services configuration file; if you wish to use a service on a non-standard port, you will have to open the specific port, as in the example above.

firewall-cmd --permanent --add-service=ssh
firewall-cmd --permanent --add-service=http

Remove a Service

As above, you specify the remove-service option, and you can close off the port that is defined for that service.

firewall-cmd --permanent --remove-service=mysql

Whitelist an IP Address

To whitelist or allow access from an IP or range of IPs, you can tell the firewall to add a trusted source.

firewall-cmd --permanent --add-source=192.168.1.100

You can also allow a range of IPs using what is called CIDR notation. CIDR is outside the scope of this article but is a shorthand that can be used for noting ranges of IP addresses.

firewall-cmd --permanent --add-source=192.168.1.0/24

Remove a Whitelisted IP Address

To remove a whitelisted IP or IP range, you can use the –remove-source option.

firewall-cmd --permanent --remove-source=192.168.1.100

Block an IP Address

As the firewall-cmd tool is mostly used for opening or allowing access, rich rules are needed to block an IP. Rich rules are similar in form to the way iptables rules are written.

firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='192.168.1.100' reject"

You can again use CIDR notation also block a range of IP addresses.

firewall-cmd --permanent --add-rich-rule="rule family='ipv4' source address='192.168.1.0/24' reject"

Whitelist an IP Address for a Specific Port (More Rich Rules)

We have to reach back to iptables and create another rich rule; however, we are using the accept statement at the end to allow the IP access, rather than reject its access.

firewall-cmd --permanent --add-rich-rule='rule family="ipv4" source address="192.168.1.100" port protocol="tcp" port="3306" accept'

Removing a Rich Rule

To remove a rich rule, use the option —remove-rich-rule, but you have to fully specify which rule is being removed, so it is best to copy and paste the full rule, rather than try to type it all out from memory.

firewall-cmd --permanent --remove-rich-rule='rule family="ipv4" source address="192.168.1.100" port protocol="tcp" port="3306" accept'

Saving Firewall Rules

After you have completed all the additions and subtraction of rules, you need to reload the firewall rules to make them active. To do this, you again use the firewall-cmd tool but using the option –reload.

firewall-cmd --reload

Viewing Firewall Rules

After reloading the rules, you can confirm if the new rules are in place correctly with the following.

firewall-cmd --list-all

Here is an example output from the –list-all option, you can see that this server has a number of ports, and services open in the firewall along with a rich rule (that forwards one port to another).

[root@alma ~]# firewall-cmd --list-all
public (default, active)
interfaces: enp1s0

Hopefully this will help a lot of you that end up just not using a firewall at all because it intimidates you not knowing how to use it correctly. Well, I’ve just eliminated that excuse, so now I want to see more of you securing your servers and dialer systems. Here is a few articles to get you started in the right direction.

Here are some more articles in relation to VICIdial security for your servers

How to – Use the built in Dynamic Portal for Vicibox
How to – Turn on IP whitelist in Vicidial
How to – Use one dynamic portal for whitelisting and have it sync across an entire cluster
How to – Fix the firewall on Vicibox10

That’s it for this article, hopefully you guys take this serious because hackers, especially ransomware thieves are targeting dialer servers in particular for their schemes, such as using the VoIP to call their victims to either trick them into downloading files or threatening them over the phone with blackmail or other means. BazarCall is one of the more well known tools thats being used by the ransomware group called Ryuk.

How to – Setup a ViciDial Cluster

This article is going to go over the steps I suggest to take in order to setup a ViciDial Cluster. I do things a little different when it comes to this to prepare for worst case scenario that a server may have problems and have to be taken offline, I install all services to each server, such as apache, mysql and asterisk this way if need be, they each can take on additional roles to cover for a server having to be taken out of production. Obviously this is going to assume you have ViciDial already installed on each server with all roles ready to go. To do so you can follow any one of my articles for scratch installs or you can just use an ISO to install of which I suggest using Vicibox v9.0.3 over V10 because of the issues with the V10 firewall and dynamic portal not working correctly, even if you do apply my fix, I find V9 to be more stable.

Step 1 – Install Vicidial on each server

As I said above, I suggest installing all services on each server and just leaving the ones not needed for each box, disabled until needed. So if you are using an ISO install instead of one of my scratch instructions, for the purpose on this article, lets say ViciBox v9.0.3. The first thing you need to do after loading v9 is to upgrade the operating system from Leap 15.1 to Leap 15.2 using these instructions, because Leap 15.1 is end of life(no more updates). After that use the command, vicibox-install and choose Y(yes) for the options shown in the picture below:

Repeat this process on each server and then move on to step 2.

Step 2 – Turn off services not needed on each server role

Now we need to disable services not needed on each server to save on resources, but this way they are there if they are needed in the future.

• DB Server: systemctl disable apache2;systemctl disable asterisk
• Web Server: systemctl disable mysql;systemctl disable asterisk
• Asterisk Servers: systemctl disable mysql

We want to leave apache running on the asterisk servers so we can install webrtc for webphones

Step 3 – Run the install.pl script on each server

Now we want to link them all together by running the install.pl script located in the source directory for vicidial, follow the following commands to get to and run it:

cd /usr/src/astguiclient/trunk
perl install.pl

Now follow the prompt and answer them accordingly. The pictures below will show the choices needed for each server role except make sure you set the IP for the DB server on all the rest instead of localhost.

DB Server and Web Server

For the web server make sure you put the DB server IP instead of localhost

Asterisk Servers

Make sure you only put 5 and 7 keepalives on one asterisk server, the rest you should only choose 123468.

Step 4 – Add them to the GUI for ViciDial

Now we need to add them into the GUI for Vicidial by going to Admin then servers

Once you are here, click “Add a new server”

Fill out the fields accordingly and click submit

Now for the DB and web server turn the options to N(no) where you see highlighted below:

Now reboot all servers and then check your reports page to make sure all servers are set to green like shown below

That’s all there is to it, not as hard as you thought it would be, right? If you have any questions feel free to join our live support on Skype:

I hope this helps!
