Teams Direct Routing - sending 2xx/3xx calls to one SBC and everything else to another...?

Hi We have M365 setup with direct routing and 2 x SBCs. SBC#1 has SIP trunks to the PSTN and SBC#2 is connected to a IPPBX. All I'd like to do is have a global rule for all Teams users so everything they dial goes to SBC#1 except when they dial 2xx/3xx/4xx only it should go to SBC#2 which will route the call to an IPPBX. I'm slightly confused if this would be done inside Dial Plans or to simply include something in each of the Voice Routes to each SBC....? Thanks

    @Solidpr01 ,

    I'm slightly confused if this would be done inside Dial Plans or to simply include something in each of the Voice Routes to each SBC....?

    This should be configured in voice routing.

    There are four elements for voice routing:

    ①Voice routing policy – A container for PSTN usages, which can be assigned to a user or to multiple users.

    ②PSTN usages – A container for voice routes and PSTN usages, which can be shared in different voice routing policies.

    ③Voice routes – A number pattern and set of online PSTN gateways to use for calls where the calling number matches the pattern.

    ④Online PSTN gateway - A pointer to an SBC that also stores the configuration that is applied when a call is placed through the SBC; can be added to voice routes.

    For more details, please refer to this article.
