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.
