How to connect with multiple PSTN providers on same tenant through Direct Routing

Hello Everyone
We are working on integration with a partner organisation.
Each organisation currently has its own tenancy, and we will plan to merge these into a single tenancy.

Also we plan to implement Teams Direct Routing for voice calls.

Each organisation currently has its own contract with a PSTN provider.
Both contracts have some years remaining.
Both PSTN providers support Direct Routing in Teams.

When we merge to a single tenancy, will we be able to maintain Direct Routing configuration with both 'local' PSTN providers?
Could we route calls to each provider based on the User's OU? Will this be very complex to configure?

Many thanks for your advice

    @Luna Gatsby ,

    Currently, official document has no claim about whether a tenant could connect to multiple PSTN providers through Direct routing or not. For more information, you could refer to this article.

    About multiple tenants, you could do tenant-to-tenant migrations and inter-tenant collaboration. However, it seems no official documents about how to merge multiple tenants.
