For example, Microsoft Calling Plans are available in specific regions, and Operator Connect requires your existing carrier to participate in the program.

    Microsoft Teams also offers the option to use integration with 105 operators worldwide using the Operator Connect option. For more information and the current list, see [Modern Work for Partners - Operator Directory](https://cloudpartners.transform.microsoft.com/partner-gtm/operators/directory).
 
    For the most flexible option, use Teams Direct Routing. You can connect your SBC to almost any telephony trunk or interconnect with third party PSTN equipment. This flexibility enables you to deploy your solution in any region or country. Remember that you need to configure the solution correctly for optimal performance and compliance with local regulations. For more information, see [Configure Direct Routing for Microsoft Teams](/microsoftteams/direct-routing-configure).
 
-- **Existing Infrastructure**: Consider your current telephony setup. If you have an existing PSTN carrier and infrastructure that you want to retain, either Direct Routing or Operator Connect might be the best option. If you prefer a fully managed, cloud-based solution with minimal on-premises requirements, Calling Plans could be the ideal choice.

 - The Teams Phone Extensibility business model for independent software vendors (ISVs) includes charging contact center as a service (CCaaS) vendors for using Azure Communication Services SDKs. This model includes Calling SDK and VoIP consumption, which require charges for each leg between the call automation bot and the CCaaS agent.
 
 - This solution also includes Audio Insights with access to mixed/unmixed audio streams or direct transcriptions. Using transcription incurs an [Azure AI Speech pricing](https://azure.microsoft.com/pricing/details/cognitive-services/speech-services/) for the selected Azure resource and Call Recording with pay-as-you-go for mixed/unmixed AV recordings. You can review current pricing for VoIP, transcription, and recording at [Azure Communication Services pricing](https://azure.microsoft.com/pricing/details/communication-services/).
 
-- End users can take advantage of their Teams Calling plans or any of the connectivity options for PSTN usage with inbound / outbound and any associated extra usage. Users must enable the required Teams licenses including Teams Phone License for any agent involved in the call including SMEs, and Resource Account license for the provisioned Teams resource account. For more information, see [Microsoft Teams Phone - Cloud Phone System](https://www.microsoft.com/microsoft-teams/microsoft-teams-phone).
