Securing your SBC Microsoft Teams Direct Routing Effectively


Microsoft Teams Direct Routing is being opted as the most recent business collaboration solution in the realm of digital communication. IT experts who deploy Direct Routing are aware of SBC security issues that arise as soon as they deploy the solution in place. A secure VoIP solution is the ultimate necessity of a company to thwart the increasing VoIP attacks emerging each day. Let’s have a look at how Microsoft deals with SBC security in its Microsoft Teams Direct Routing Solution.

The “friendly” attacks during configuration

An IT communications expert who was hired to deploy Microsoft Teams Direct routing in a cloud business, narrates his experience:

“While I was deploying Microsoft Teams Direct Routing with SIP trunks and a Session Border Controller (SBC), I happened to sense various SBC security vulnerabilities soon after I turned up the public interface. Long before the Teams configuration was complete there appeared a number of OPTIONS requests and huge SIP traffic from unknown sources. This traffic was supported by IP addresses trying to connect to my systems from around the world via malicious SIP scripting and scanning utilities. It was an alarming situation for me. Headers like “SIP Vicious”, “friendly-scanner”, and “PPLSIP”.

This scenario is not a unique one. All over the internet, attackers are in search of vulnerabilities. While SBCs are scanned in order to attempt hijack calling capabilities, admins can take this opportunity while deploying Microsoft Teams Direct Routing to configure and test the security rules provided by Direct Routing. There are two ways to secure your system: by configuring firewall and using Malicious Signatures feature.

Teams Direct Routing solutions to boost your business productivity

A properly configured Firewall, is your best friend forever

There are options to configure a Firewall for better security. All you have to do is configure the rules properly in the following manner:

  1. Exclude the LAN interface from Firewall list
  2. Allow external DNS lookups
  3. Allow Teams traffic
  4. Allow Signaling and RTP traffic
  5. In the final step, configure using: Block All others option.

Once these configurations are in place, you will no longer see or experience any malicious attempts. In fact, you will be able to see the number of attempts being blocked/dropped is increasing.

The Malicious Signatures feature for better security

A Malicious Signatures feature blocks all the attempts coming from malicious signatures and only allows the attempts from legitimate signatures. To make use of this feature, the admin has to configure a message policy. After this he has to malicious signatures database. Using this message policy, you can drop malicious SIP messages and set well defined limits. This policy can be assigned to the concerned SIP trunk.

7 key terms to unleash the technology behind Unified communications


Looks like the times of cloud communications are advancing towards unified communications as discussed heatedly in the past. The technologies like video conferencing, mobility, and omnichannel contact centers, UC APIs, and of course the CCaaS and UCaaS hosted solutions are now in the mainstream pertaining to the high demand of business centric communications platforms. With the rise of high quality video streaming needs and workspaces not being confined to mere office desktops but have expanded over hosted workplace solutions, Teams and projects management demands much more than just an office suite to meet-state-of-the-art challenges, it needs something robust. It requires Unified communications.

The basic requirement which has driven unified communications to this stage is that communication requires minimal jitter, minimum delay/latency, and minimum packet loss. This forms the basis of how communications have evolved from simple Phone systems, in which the digital aspects had been included in order to make streamline communications as compared to analogue communications, towards PSTN, where wired connections were established with the help of circuits to streamline voice over a phone assigning Uniform Resource Identifier (URI) to each device for better access, to Voice over IP (VoIP)where The Internet was introduced for cost-effective business communication in a streamlined manner. Yet, with internet the requirement of less jitter/delay/packet loss was a big challenge.

To tackle that challenge, IP PBX systems and Hosted PBX systems are introduced that take business communication one step towards unified communications as of today. The premise-based IP PBX system was developed with LAN and IP technologies combined whereas the hosted PBX is a more robust and cost-effective solution, hosted in the cloud and matured over the years, to serve the purpose. Amongst IP PBX systems and Hosted PBX systems, deployment decisions can be taken based on Upfront Cost, Recurring cost, Technology Infrastructure and TCO.

Moving fast forward, SIP trunking is the most promising technology of today. Been made the new standard as the phone call protocol of choice replacing the traditional PSTN systems, SIP makes best-in-breed voice and Internet solutions possible for modern business voice, video and multi-party conference call needs. A few SIP trunking features include:

  • Minutes don’t matter:  with SIP trunking, you are offered unlimited inbound and outbound phone calls.
  • Bye-bye hardware: Traditional Line cards are not needed in most cases now, so there is no hi-fi infrastructure establishment needs for providers. Hosted SIP is the solution that eliminated hardware needs yet providing best voice and multi conferencing needs efficiently.
  • Geographic Resilience: the infrastructure in the cloud is established with Disaster recovery feature been kept in mind. Hence, you are always connected even under a catastrophic event.
  • Calls info: calls information can be achieved from Caller ID, Caller Name ID DID and virtual phone number features are present in SIP trunking.
  • Geographic Location Independence: with the flexibility of call routing through an IP, it doesn’t matter where you are in the world. The service is highly available wherever you are.

Who offer these services?

Telco’s and SIP providers offer these call and conferencing services with affordable rates that make you save up to 50% on your business phone bill every month. These providers offer Call volume and internet connection that is all you need for a better communication experience. There are two types of providers:

  • Single Solution Provider: the ones who offer both SIP trunks and data circuits. They provide bundles pricing offers, better quality and the best part is, if there’s an issue there’s only “one throat to choke”.
  • Over The Top (OTT) provide SIP trunking over another data carrier circuit. Companies like Netflix made the term OOT mainstream over the internet. With these providers, you can implement solutions from Best of Breed Providers both in terms of quality and pricing. And with this approach, you can always choose to discontinue the service that isn’t working too well.

The Quest for best continues

We’re old enough to remember the most used tagline in every phone call in the 90’s:

‘Can you hear me now?’

But not anymore; the journey to achieve best communication method continues all these years and it gets us landed into the world of Unified communications. Hosted SIP, VoIP, inherent multiple-carrier solutions, IP PBX, Hosted PBX and other terms are basic building blocks of Unified communications. You can call it the communication of “everything”.
