Yes, if you have multiple SIP trunks that you want to link with Microsoft Teams, this is easily possible with the Teams Connector.
It doesn’t matter which provider the SIP trunks come from. Not only do you have access to a growing number of certified third-party providers, but thanks to the generic template for setting up trunks, you can integrate SIP trunks from almost any provider worldwide.
The local network of the SIP trunk is also irrelevant for the connection to Microsoft Teams – you can, for example, connect several branches or company locations to Microsoft Teams and bundle the communication there.
