SBC Core should be configured for Teams Direct Routing and PSTN with the below link:

https://doc.rbbn.com/display/ALLDOC/SBC+8.2+-+Configure+SBC+for+MS+Teams


Info

Follow the section from Common SBC Configuration till Configure SBC for MS Teams Media Bypass.


Info
  • When using media bypass, the media between the Teams client and the SBC is using the SBC external (public) interface.
  • This solution is to allow calls to/from the SIP trunk/PSTN, when connectivity to Microsoft Teams is lost – survivability mode.

...

SBC Core has an Embedded Routing Engine (ERE). It can be configured as mentioned in the link below:

https://doc.rbbn.com/display/ALLDOC/SBC+8.2+-+Configure+ERE+for+MS+Teams


Note

Once the above 2 sections are configured, proceed with the below mentioned sections.

...

Note

Attach the TLS Profile created earlier in Configure SBC for TLS.


Warning

There are a few areas that result in a TLS negotiation issue. One area involves assigning the incorrect port. Ensure the following are accomplished: 

  • SBA listens on port number 5061 (default setting).

  • Configure port number 5060 on the SBC IP-Peer, since Ribbon SBC Core increments the port by 1 when the transport protocol is TLS.

...

Create a SIP Trunk Group towards the SBA and assign the corresponding profiles such as PSP and IPSP which were created in earlier steps.

Warning

As SWe Core would be interacting with Virtual Survivable Branch Appliance (vSBA) in the current deployment scenario, configuring Step 3: Configure SBC SWe Edge is not required, as this step is strictly for deployment scenarios involving Ribbon SWe Edge and vSBA.
