Direct Routing SBC failover planning in carrier hosted setup (derived trunk model)
Hi, I am trying to setup Teams Direct Routing in our network using the hosted carrier model using two SBCs which are in active/active setup for outbound and inbound calls. I haven't begun any con...
For hosting provider failover routing, the hosting provider will need to configure multiple PSTN gateways in their tenant. For example:
- sbc1.contoso.com
- sbc2.contoso.com
This will require multiple wildcard san names to support each namespace. For example:
- *.sbc1.contoso.com
- *.sbc2.contoso.com
Each customer will be provide two FQDN's to be added to Tenant domain and a single user licensed for SfB Online in the namespace to create the domain in the service forest. For example:
- cust1.sbc1.contoso.com
- cust2.sbc1.contoso.com
Then a route will be created for each of these gateways.

These were all just examples. Let me try to make this simpler without specific names.
Carrier Tenant Online PSTN Gateway(s), can be one or greater if failover is being handled by multiple FQDNs.
- sbcBaseName1.carrier.com
- sbcBaseName2.carrier.com
Carrier certificate SAN names
- *.sbcBaseName1.carrier.com
- *.sbcBaseName2.carrier.com
Customer Tenant Domain Name and SBC named used in Route configuration
- cust1.sbcBaseName1.carrier.com
- cust2.sbcBaseName2.carrier.com
The pattern here is that the carrier PSTN Gateway is the base name for which customer names are derived. The customer names will be a single level child of the base domain.
Hope that helps.
Hello
The wildcard certificate to be applied on DR-SBC is *.sbcBaseName1.carrier.com in your example. What about sbcBaseName1.carrier.com name? Does it need to be included in certificate too?
