As of release version 2.15 it is possible to configure SIP Trunks to route calls to Microsoft Phone system using Operator Connect, as an alternative to Direct Routing.
The purpose of Operator Connect Express, accomplished through a partnership with SIPPIO, is to allow ConnecttoTeams resellers and partners to provision PSTN connectivity to organizations that request Operator Connect. The primary benefit, as compared to telephony integration with Direct Routing, is that Operator Connect does not require any permissions from the organization's Microsoft Administrator. This integration does not provide a tile in the Teams Operator Connect portal.

When adding or editing a Reseller, do the following:

Important
Although the Enterprise Admin Email ID is required by the form, there is no action required by the enterprise Global Administrator for Operator Connect. Therefore, any email address can be used and the registration email can be ignored. If the enterprise will be using other Connectors, then the Enterprise registration by email is required.
The SBC Region is required by the form, but not needed for Operator Connect. Therefore, any region may be chosen.
Upload DIDs
Follow the instructions for uploading DIDs here being sure to specify "Operator Connect" as the voice route Type in the appropriate column of the csv file.
Configure Operator Connect

2. Select the desired values for the DID configuration:
Phone Number - The DID that you are configuring.
Reseller - The Reseller of the DID that you are configuring.
Enterprise - The Enterprise of the DID that you are configuring.
Trunk Profile - The SIP Trunk that will be used for outbound calling for this Enterprise. If needed review the instructions to create and manage a Trunk Profile here.
Region - The Azure region that will serve this DID
Civic Address - The location that will be used for Emergency 911 services and is required. The drop-down selector will show all addresses that are configured in Teams Admin Center. If needed, review the Microsoft article here to understand how emergency locations are managed in Teams.
DID Activation: After the DID is configured the status will be displayed as "in progress" - a process that can take several minutes to complete. To update the status, reload the Phone Number page. If the DID does not show as activated after several minutes, contact your service provider for support.

After DID activation is complete, the DIDs will be available in Teams Admin Center for further configuration under the Voice->Phone Numbers menu option. If necessary, review the Microsoft article here to learn about managing phone numbers.
Number Provider: Note that the Number Provider displayed in the Teams Admin Center will be SIPPIO. However, the DIDs and all inbound/outbound calls will be routed to the SIP Trunk Profile configured by you.
