Understanding VoIP
Understanding VoIP is key to making the most of its benefits. VoIP, or Voice over Internet Protocol, is a technology that allows you to make phone calls over the internet instead of traditional phone lines.
VoIP works by converting your voice into digital signals that can be transmitted over the internet. This is why you need a stable internet connection to use VoIP.

The science behind VoIP is complex, but essentially, it's a more efficient and cost-effective way to make phone calls. According to Aircall, VoIP technology makes sense for your business phone.
To set up VoIP, you'll need an IP phone or a device that can connect to the internet. IP phones are designed specifically for VoIP and can be connected to your router or modem.
Here are some key features you can expect from a VoIP provider:
- VoIP phone number
- IP phone
- Cloud-based services
- Business VoIP phone service
- Hosted VoIP
These features will help you understand what to look for in a VoIP provider and how to choose the best one for your business.
Call Management
Call management is a breeze with VoIP. You can receive calls on your unique SIP number, which comes with no monthly fees, and use it to receive free calls from other VoIP users.
You can also purchase a Virtual Phone Number to receive calls from traditional or mobile phones. This number acts as an alias for your VoIP account, allowing calls to connect seamlessly.

Some advantages of Virtual Phone Numbers include the ability to keep your number wherever you go, choose any area code, and select an international number for global access.
Here are some features you can expect with VoIP call management:
- Voicemail to email
- Call forwarding
- Caller ID
- Cloud PBX
Call forwarding is a convenient feature that lets you forward calls to any mobile or landline worldwide. The rates for call forwarding vary depending on the destination, but you can check the exact rates on the VoIP website.
Determining a Call
Determining a call can be tricky, especially with the rise of VoIP technology.
Unfamiliar area codes, multiple zeros, or a sequence of random digits on your phone display can indicate a VoIP call.
Certain VoIP providers can make calls appear as if they originate from your area code, making it harder to identify.
VoIP calls are made through an internet IP address, which can be shared by multiple numbers.
The caller might have a different number assigned to them the next time they call, making it even harder to track.
Using a VPN can further complicate tracing the call.

Trace a Call
If you're trying to trace a VoIP call, a simple domain or IP address lookup might solve your problem. However, if the caller is using a non-fixed VoIP number, it can be challenging to trace.
Fixed VoIP numbers are typically associated with a specific physical location and are easier to trace. Non-fixed VoIP numbers, on the other hand, aren't tied to a specific address, making them more elusive.
Reaching out to authorities to trace calls is also an option if the VoIP calls are threatening or pose a real security or legal risk. This is especially true if the number is shared, encrypted, or otherwise hidden.
You may need to lean on a technically adept person or team to use more advanced tools if you're dealing with a non-fixed VoIP number.

Call Quality and Connectivity
High packet loss is the primary reason why VoIP calls drop. This can occur when a sufficient number of VoIP packets are lost in the conversation.
Network instability can also cause calls to drop, especially if a network link flaps down and up.
Here are the primary reasons why calls drop, in priority order:
- High packet loss
- Non-VoIP related drops
- Network instability
- Gateway resource limitations
- Soft-phone limitations
- Virtual server limitations
Why Calls Drop
Call drops can be frustrating, but understanding why they happen can help you troubleshoot the issue. High packet loss is a common reason for call drops, and it's usually due to a sufficient number of VoIP packets being lost in the conversation.
Non-VoIP related drops can also occur, where a call is dropped because the remote user's cell phone dropped the call. This can be confirmed by looking at the CDR's call disconnect reason.
Network instability can cause calls to drop, especially if a network link or device goes down. This can also happen if a network link flaps down and up, causing instability.
Gateway resource limitations can lead to call drops if a VoIP gateway runs out of resources like memory, buffers, or CPU utilization. Soft-phone limitations can also cause call drops if the PC running the call is resource-starved or starts an antivirus scan.
Virtual server limitations can cause call drops if the voice stream of the call is being run through a voice processing server that is running as a virtual server. The virtual machine needs to be properly tuned to run real-time applications.
Here are the primary reasons why calls drop, in priority order:
- High packet loss
- Non-VoIP related drops
- Network instability
- Gateway resource limitations
- Soft-phone limitations
- Virtual server limitations
Using WiFi for Calls
You can make business calls over your internet connection, even if you have poor cell reception. This way, you can stay connected with your team and clients no matter where you are.
Save your minutes and data by switching to WiFi for outbound calls and texts. This can be a huge cost-saver for businesses that rely on mobile communication.
With WiFi calling, you'll never miss important calls or texts because you'll be accessible from anywhere with an internet connection. This is especially useful for remote workers or those who travel frequently.

Analyze the Domain
Analyzing the domain of a VoIP call can be a useful step in troubleshooting call quality issues. This is because VoIP providers like Nextiva display domain information in call logs, which can help identify the caller's origin.

You can find this information by logging in to your VoIP dashboard and accessing your call details or call history. An example entry might show the caller's name, number, and domain, along with the date and time of the call, and its duration.
In some cases, the domain address may appear as a string of numbers, such as 203.0.113.12, which represents the origin of the VoIP call. This can be converted to an IP address using online tools like RankWatch's free domain to IP converter.
To find out who owns a domain and where it's located, you can use tools like ICANN Lookup or Nord VPN's IP Address Lookup. Here are some options to consider:
- Domain Lookup: Use ICANN Lookup to find information about who owns a domain
- Domain to IP Converter: RankWatch's free tool will give you a domain's IP address and its general location
- IP Address Lookup: If you already know the IP address, Nord VPN's IP Address Lookup will help you find the hostname and more precise geolocation of that caller
Call Security and Troubleshooting
Call security is a major concern for businesses using VoIP technology. The biggest security risks involved in using VoIP include being vulnerable to attacks that can compromise your business's communication system.
To protect your business from attack, it's essential to understand the security risks involved with VoIP. We've answered some of the biggest security risks in the article.
One way to ensure call security is to implement firewalls and secure protocols to prevent unauthorized access to your VoIP system.
Tracing Fixed vs. Non-Fixed Numbers
Fixed VoIP numbers are typically associated with a specific physical location and are easier to trace.
Non-fixed VoIP numbers, on the other hand, aren't tied to a specific address, making them more elusive. This can make it challenging to trace the call on your own.
If you're dealing with a non-fixed VoIP number that isn't attached to a physical address, or if the number is shared, encrypted, or otherwise hidden, it will be difficult to trace the call.
Reaching out to authorities can help you trace these kinds of numbers, but only do so if you suspect that the caller is up to something sinister.

Core Security for Businesses
VoIP security is a top concern for businesses. According to "What Every Business Should Understand About VoIP Security", the biggest security risks involved in using VoIP technology include unauthorized access to sensitive information.
Protecting your business from attack requires implementing robust security measures. This includes using secure protocols for VoIP communication, such as Secure Real-time Transport Protocol (SRTP), to prevent eavesdropping and tampering.

Regularly updating your VoIP system and network is essential to prevent exploitation of known vulnerabilities. This can be done by applying security patches and updates to your VoIP software and firmware.
Implementing firewalls and intrusion detection systems can also help prevent unauthorized access to your VoIP network. By blocking suspicious traffic and alerting you to potential threats, these systems can help keep your business safe.
By taking these steps, businesses can significantly reduce the risk of VoIP security breaches and protect their sensitive information.
Diagnose IP Using Wireshark
Wireshark can be a powerful tool for tracing the origin of VoIP calls. It's a network packet analyzer that captures detailed data flowing between systems on a network.
To use Wireshark effectively, start by capturing VoIP traffic on the network interface through which the call is passing. This will help you filter out irrelevant data and focus on the VoIP packets.
Common VoIP protocols include SIP, H.323, and RTP. Look for SIP or H.323 packets, which contain signaling information about the call. You can see the source IP address of the call initiator in these packets.

However, keep in mind that Network Address Translation (NAT) and encryption can complicate the process. NAT often hides internal IP addresses, while encryption makes it challenging to intercept and understand the VoIP content.
If you're interested in tracing the actual voice data, you can also analyze RTP streams in Wireshark. This can reveal the source and destination IP addresses and ports used for the audio stream.
Here are the steps to diagnose IP using Wireshark:
- Capture VoIP traffic on the network interface through which the call is passing.
- Filter the capture to focus on SIP or H.323 packets, which contain signaling information about the call.
- Analyze RTP streams to reveal the source and destination IP addresses and ports used for the audio stream.
Tracing a Call Is Possible
Tracing a call is possible, but it's not always easy.
If the caller is using a fixed VoIP number associated with a specific physical location, it's relatively easier to trace. However, non-fixed VoIP numbers, which aren't tied to a specific address, can be more elusive.
You can use a network packet analyzer like Wireshark to capture and analyze VoIP traffic. This can reveal the source IP address of the call initiator, but keep in mind that Network Address Translation (NAT) and encryption can complicate the process.

In some cases, the originating IP addresses may not always be trustworthy due to spoofing.
To use Wireshark effectively, you'll need to filter the capture to focus on the relevant traffic, typically VoIP packets. Common VoIP protocols include SIP, H.323, and RTP.
Here's a step-by-step guide to diagnosing the IP using Wireshark:
- Capture VoIP Traffic: Start Wireshark and initiate a packet capture on the network interface through which the VoIP call is passing.
- Identify SIP or H.323 Signaling: Look for SIP or H.323 packets, which contain signaling information about the VoIP call.
- Analyze RTP Streams: If you want to trace the actual voice data, Wireshark can also capture and analyze RTP streams.
It's worth noting that tracing a VoIP call can be complex, but it's not impossible. If you're dealing with a non-fixed VoIP number, you may need to reach out to the authorities for help.
