LCR in Teams Direct routing

Hi,

Yes for the different countries based on the Local Regulations Least Cost Routing is not available. Specially for the countries like India, China, Middle East where our telco regulations are strict and to comply with the Local Telco Regulation we need to ensure that we have the Teams Direct Routing deployed with Location Based Routing.

1. They can leverage the feature for enabling the usage of SBC in multiple different countries for their International Users.
2. Yes LCR can be configured with Direct Routing.
3. Personally I haven't seen any documentation for the same but the configuration is very much possible and most of our giant carriers have configured LCR in their backend to optimize the cost.
4. I can't share the diagram but the following article should be helpful

Let me know in case you need additional information happy to support.

With Regards,
