This document outlines the configuration best practices for the Ribbon solution covering the Ribbon SBC Core SWe when SWe when deployed with Microsoft Teams vSBA (virtual Survivable Branch Appliance).
...
A Session Border Controller (SBC) is a network element deployed to protect SIP-based Voice over Internet Protocol (VoIP) networks. Early deployments of SBCs were focused on the borders between two service provider networks in a peering environment. This role has now expanded to include significant deployments between a service provider's access network and a backbone network to provide service to residential and/or enterprise customers.
The SBC Core Core (SBC 5K, 7K, SWe) addresses the next-generation needs of SIP communications by delivering embedded media transcoding, robust security, and advanced call routing in a high-performance, small form-factor device enabling service providers and enterprises to quickly and securely enhance their network by implementing services like SIP Trunking, secure Unified Communications, and Voice over IP (VoIP).
The SBC Core provides Core provides a reliable, scalable platform for IP interconnect to deliver security, session control, bandwidth management, advanced media services, and integrated billing/reporting tools in an SBC appliance. This versatile series of SBCs can be deployed as peering SBCs, access SBCs, or enterprise SBCs (eSBCs). The SBC product family is tested for interoperability and performance against a variety of third-party products and call flow configurations in the customer networks.
Note |

SBC 5x10, 5400, 7000, and SWe are represented as SBC Core in the subsequent sections. |

The Direct Routing Virtual Survivable Branch Appliance (vSBA) is a Ribbon Communications SBC SWe Edge offer accomplished through close cooperation with Microsoft®. The vSBA allows users to make and receive Public Switched Telephone Network (PSTN) calls when there is an outage.
When a customer site using Direct Routing to connect to Microsoft Phone System experiences an internet outage, the intranet inside the branch is When a customer site using Direct Routing to connect to Microsoft Phone System experiences an internet outage, the intranet inside the branch is still fully functional. Users can connect to the Session Border Controller (SBC) that is providing the PSTN connectivity.
During an internet outage, the Teams client should switch to the SBA automatically. No action is required from the user. As soon as the Teams client detects that the internet service is restored and any outgoing calls are finished, the client will fall back to normal operation mode and connect to other Teams services.
The interoperability compliance testing focuses on verifying inbound and outbound call flows between the Ribbon SBC SWe Core & Teams vSBA.
Note |
---|
Direct Routing vSBA is available on the SBC SWe Edge Release 11.0x and later. Contact your authorized Ribbon sales representative/partner for more information regarding approved SBC SWe Edge Direct Routing vSBA platforms and acquisition. |

Mgmt is is an RJ45 port and is the management interface of the SBC. Media 0/Media1 Media1, depicted as pkt0/pkt1, are RJ45 OR optical SFP ports. Media 0 and Media 1 are used in the current deployment and the same interfaces can be used in SBC Core 5K and 7K (appliance based). Typically, on 5K/7K these ports would be optical SFPs. For the SBC SWe (virtualized platform), the logical pkt0/pkt1 interface must be mapped to a physical portport. |

Prerequisites:
Generate a CSR with OpenSSL
Code Block |
---|
# To create a Certificate Signing Request (CSR) and key file for a Subject Alternative Name (SAN) certificate with multiple subject alternate names, complete the following procedure:
Create an OpenSSL configuration file (text file) on the local computer by editing the fields to the company requirements.
Note 1: In the example used in this article the configuration file is req.conf.
Note 2: req_extensions will put the subject alternative names in a CSR, whereas x509_extensions would be used when creating an actual certificate file.
[req]
distinguished_name = req_distinguished_name
req_extensions = v3_req
prompt = no
[req_distinguished_name]
C = US
ST = VA
L = SomeCity
O = MyCompany
OU = MyDivision
CN = www.company.com
[v3_req]
keyUsage = keyEncipherment, dataEncipherment
extendedKeyUsage = serverAuth
subjectAltName = @alt_names
[alt_names]
DNS.1 = www.company.com
DNS.2 = company.com
DNS.3 = www.company.net
DNS.4 = company.net
Make sure there are no whitespaces at the end of the lines.
#Run the following commands to create the Certificate Signing Request (CSR) and a new Key file:
openssl req -new -out company_san.csr -newkey rsa:2048 -nodes -sha256 -keyout company_san.key.temp -config req.conf
#Run the following command to verify the Certificate Signing Request:
openssl req -text -noout -verify -in company_san.csr
# After receiving the CSR with above information, provide it to CA (Certificate Authority). You will then receive the proper CA signed certificate in .crt format that is convertable into other formats using openssl.
# By default, you should receive two or more certificates from CA (depanding upon your CA). One is the SBC certificate, and other is CA's root and intermediate certificate.
# Upload the certificates to the SBC at /opt/sonus/external and convert them into SBC-readable format, i.e. SBC certificate is in .pem or .p12 format and root certificate is in .cer or .der.
#Converting .crt to .pem USING OPENSSL for SBC certificate.
openssl x509 -in sbc_cert.crt -out sbc_cert.der -outform DER
openssl x509 -in sbc_cert.der -inform DER -out sbc_cert.pem -outform PEM
#After generating sbc_cert.pem file, convert it to .p12 format using below command and the location of the certificate key.
openssl pkcs12 -export -out sbc1_cert.p12 -in sbc_cert.pem -inkey /opt/sonus/company_san.key.temp
#CONVERTING CRT to CER USING OPENSSL for CA's root and intermediate certificate.
openssl x509 -in root_cert.crt -out root_cert.cer -outform DER
After converting all these certificates upload them on SBC at /opt/sonus/external location. |

Microsoft requires a SHA256 certificate for the Direct Routing vSBA in order to establish a TLS connection with the SBC. See the following options:
Shared SBC Public certificate (recommended). This is only possible if your SBC certificate matches one of the following options:
SBC Certificate is a wildcard certificate
SBC Certificate Common Name "CN: *.mydomain.com" or SBC Certificate Subject Alternative Name "SAN: *.mydomain.com".
SBC Certificate has a SAN for Direct Routing vSBA
SBC Certificate Common Name "CN: sbc.mydomain.com" and SBC Certificate Subject Alternative Name "SAN: sba.mydomain.com".
Use an existing Public or Private Certificate that covers the Direct Routing vSBA FQDN.
Create a new Public or Private Certificate that covers the Direct Routing vSBA FQDN. In this case, a Public or Private Certificate Authority must be ready to sign the certificate for the Direct Routing vSBA.

A Trusted CA Certificate is a certificate issued by a trusted certificate authority. Trusted CA Certificates are imported to the SBC Edge Portfolio to establish its authenticity on the network.
Warning |
---|
Most Certificate Vendors sign the SBC Edge Portfolio certificate with an intermediate certificate authority. There is at least one, but there could be several intermediate CAs in the certificate chain. When importing the Trusted Root CA Certificates, be sure to import the root CA certificate and all Intermediate CA certificates. Failure to import all certificates in the chain causes the import of the SBC Edge Portfolio certificate to fail. |
