We co-hosted a Security webinar Part I with Sangoma this Tuesday and our audience had a lot of questions regarding SBCs, VPN, dynamic IPs, PBX and other security issues. We would like to share the Q&A session with all of you who may have the same questions!

Also, don’t forget the Security Webinar Part II is coming on February 6th! Register early to save your seat!

1. For the session border controller if we have any IPS static do we need one? Then we wouldn’t have ports open to the entire world but only from specific?

Answer: This will protect you as long as your users do not have infected devices at that IP address. Putting a SBC into the equation ensures that only the traffic you want passes onto your network.

2. What if you use a VPN? Do you still need a SBC?

Answer: VPN will secure the device (in this case the IP phone), but you are still opening up ports for your SIP provider. You must also consider the fact that your user may connect an infected PC or Laptop to that phone, which would now have a secure connection directly to your LAN. The same thing applies if your users are using a softphone over VPN using an infected device.

3. If we use remote phones and they are on dynamic IP’s or travel then we should be using an SBC?

Answer: Absolutely.

4. I would imagine VPN from endpoints to PBX, like OpenVPN with the Sysadmin Pro module. So if I have FreePBX, Sysadmin Pro module with Sangoma phones running OpenVPN, what does adding the SBC get me? SIP trunks, like Bandwidth or Flowroute. The PBX is hosted.

Answer: VPN will secure the device (in this case the IP phone), but you are still opening up ports for your SIP provider. You must also consider the fact that your user may connect an infected PC or Laptop to that phone, which would now have a secure connection directly to your LAN. The same thing applies if your users are using a softphone over VPN using an infected device.

5. What if our phone system is cloud hosted. Do we need an SBC?

Answer: Yes. Since you would need to open ports on your firewall to allow SIP traffic thru to your phones.

6. If you are using HA do you need 2 SBCs?

Answer: Since the two PBXs are on the same network, you would only need 1 SBC.

7. What if the SBC fails in the field.  Do you need a hot-swappable or can you run the system without the SBC?

Answer: A system will run without it and hopefully your backup security strategies will protect you until you get another SBC deployed. If security is your number 1 priority you should have a backup if your budget allows for it.

A Session Border Controller (SBC) is a powerful back-to-back user agent device that sits at a point of demarcation for SMB and Enterprise businesses to provide services such as call control, security, interoperability and voice optimization. Let’s take a closer look at how a Session Border Controller works to optimize your VoIP performance!

Generally, the main duties of an SBC can be separated into four sections: Topology Hiding, IP Addresses Translation, Encryption and Transcoding, and Classification.

Topology Hiding

An SBC locates in the middle of the call path between a service provider and an IP-PBX. When a call is generated and arrives at an SBC from the PBX, the SBC filters out any sensitive information, so no outside intruders can exploit this information for hacking the enterprise VoIP network. This is called Topology Hiding.

IP Addresses Translation

An SBC also translates local IP addresses of the callers to the WAN IP address of the SBC and performs protocol normalization, a process that an SBC manipulates the call message to adhere to the service provider’s protocol implementation including possible number manipulation.

how-does-sbc-workEncryption and Transcoding

Some SBCs also encrypt calls and perform transcoding when necessary. If an enterprise is connected to multiple branches and service providers, an SBC will decide where to route the calls to. It makes routing decisions based on multiple criteria: reachability, call cost optimization and path with the best quality.


So far, we have only talked about the outgoing calls. What about the incoming calls? It basically follows the same steps as for outgoing calls but with one extra layer of examination which is called classification, a process of careful inspection on the incoming calls to identify intruders and hackers.

Are you on board and benefiting from VoIP? Greate! But do you have protections for your VoIP network? You may have heard that, like other Internet-based systems, VoIP networks are also vulnerable to IP-based attacks such as denial-of-service (DoS) attacks and identity/information theft. Luckily, with a proper security measure, you will be able to effectively block out the unwanted intruders!

Patton’s SmartNode SIP Session Border Controllers enable Unified Communications for SIP-to-SIP environments and contain built-in security features and Stateful Firewall. They secure the LAN networks from fraud strikes on the Internet. Even better, Patton products come with free post-sales technical support and a 1-year warranty. All products are made in USA. Let’s check out their four most popular SN selections!

Cost saving is one of the main reasons for many businesses and enterprises to move to VoIP. For businesses that deploy SIP trunks, it may be tempting to cut corners by using lower cost network elements, or by omitting some devices they considered “non-essential” but nice-to-have.

One question we often hear is “Why can’t I just connect my IP Phone or IP PBX to a SIP trunk?” Well, to answer that question, let’s take a look at the risks you are exposed to without an extra protection.

Issue #1 – Security

You may encounter unexpected high phone bills. According to the Communications Fraud Control Association (CFCA) report, the Internet-based toll fraud cost small business victims $6.08 billion in 2015. Hacking, spamming, and tampering are difficult to prevent without an extra layer of protection.

Failing to encrypt the SIP signaling data can expose such information as user credentials, phone numbers, IP addresses and aspects of the company network topology to malicious intruders.


Both SIP signaling information and media content (digitized voice) must be protected (hidden) by encryption.

A high-quality eSBC like Patton’s SN4451 Series will provide a rich set of security features that protect the provider WAN network and the customer LAN from each other, as well as from external security vulnerabilities.

Issue # 2 – Reliability 

IP telephony operates over a complicated computer-based network and it can have network failure and downtime if it’s not protected. Such network failures can cause gaps in a company’s phone service resulting in disrupted communications and loss of business continuity.


Patton’s SN4511 eSBCs provides a failover mechanism, and that also provides media gateway and IP routing functions, can deliver survivability for voice and data over a fallback connection to the local phone company (PSTN).

Issue #3 – Service Quality

Bad service quality is the worst. You could lose customers or subscribers because of the poor voice quality or unreliable service.


Patton’s SN4451 eSBCs provide dual Quality of Service (QoS) mechanisms that include:

  • Bandwidth Reservation – minimum link capacity allocated for voice packets
  • Downstream QoS – throttling mechanisms that limit and slow down large downstream data bursts to prevent flooding the capacity of the link.

Issue #4 – Interoperability

Potential business customers have selected innumerable brands of (traditional or IP-based) PBXs and phones. How many can you realistically certify for guaranteed interoperability with your network elements, protocols, and services?


Patton’s eSBCs provide legacy interfaces that IP-enable existing ISDN and POTS business phone systems helps businesses preserve the value and extend the useful life of their capital investments in traditional telephony solutions. While taking advantage of the cost-saving and operational benefits of IP telephony, such solutions enable companies to migrate to converged communications at the pace they deem most comfortable and cost-effective.
