Secure calling with Microsoft Teams. Prevent security risks in telephone conversations


Microsoft Direct Routing is a gateway that connect Microsoft Teams with the Telephony network.  Every Direct Routing connection is intended for a single company (single-tenant) and is connected to a Session Border Controller (SBC) via an encryption connection. Nowadays SBC are often offered as a virtual server in a public Cloud service or data center. This set-up carries a security risk.

When an SBC is connected to the telephone network, an unencrypted SIP trunk via the internet is often used. Voice packets are sent over the internet without encryption. In addition, the infrastructure and / or SBC is managed by third parties that can store conversation data. Certainly, if public Cloud Services are used, it is not possible to determine who can access the data and who can access calls.

Teams direct routing with MachCloud

The MachCloud VoIP platform has extended the encryption of speech via Direct Routing to the VoIP platform itself. This prevents speech packets from being sent over the internet without encryption. With this solution it is also not necessary to use an SBC.

In addition, an existing telephone exchange will often be used in addition to the telephone service from Microsoft Teams. The CloudPBX from MachCloud has the ability to control encryption up to the SIP phone. It is also possible to only transport voice over a private network instead of the Internet. Only with these measures is it possible to minimize risks of voice traffic security breach.

5 Microsoft Teams Direct Routing Features to Look Forward [2020 Guide]


Microsoft Teams Direct Routing is the latest trend in modern digital business communication. This is a scenario where companies can bring in their existing SIP Trunk/Carrier/SBC and connect it with Microsoft Teams and avail its benefits with User PSTN Telephony. This ensures better productivity and fewer changes required to the existing infrastructure.

A while ago, Microsoft announced a few enhancements that are promised in Microsoft Teams Direct Routing. Let’s go through them:

Media Relay Override

With this, customers can “change their default Media Relay to match their public IP structure”. With a Media bypass plan setup, media is kept directly between Session Border Controller (SBC) and Teams user.

Missed Call Message Suppression

Since Teams can go on along with an existing 3rd Party PBX, this feature enables Teams not to miss any notification if a gateway is setup in such a way that it rings or forks a call (on both Teams and PBX) and the call is picked up on PBX or PBX’s voicemail.

SIP Tester

It is a feature to be introduced for convenience. A PowerShell script is introduced which will test the basic configuration of SIP deployment over Direct Routing in Teams.

Ringback Bot

It is available for Direct Routing in non-media bypass mode. During the call imitation process, the Ringback Bot is helpful in ringing a distinctive audio signal to the caller while there are any unexpected silences while the inbound call is being placed from the public switched telephone network (PSTN) to Teams clients.

PSTN Reporting

With this feature, you’d be able to get PSTN Call Detail Records reports directly in your Microsoft Teams Admin Centre. Reports can be viewed for a historical trend for 28 days and also till any custom date. With this feature, you can easily have a look at a detailed analysis of Microsoft Teams PSTN usage.
