Multiple MS Teams carrier model deployed on 1 SBC cluster

Hi,

we are using the Teams carrier deployment model on our SBCs. The ideal plan is to host several carrier domains/FQDNs on 1 SBC cluster. So the carrier model, but then for more domains.

The challenge we're facing is not the configure extra SIP interfaces, realms etc etc, but the Local Policy routing.

Normally calls to Teams are routed to SAG_Teams, but the attached SA's (sip.pstnhub.microsoft.com) are linked to a specific realm (with FQDN info). So when we want to use multiple carrier FQDN's we can create extra realms, but not the extra SA's because the SBC doesn't allow to create multiple SA's with the same name sip.pstnhub.microsoft.com.
