The enterprise originally had an SBC platform. In order to maximize the use of existing resources, it hopes that the Teams platform and SBC can share the access telecommunication lines and code numbers.

Extensions with Teams accounts at each site access the platform through the software and hardware terminals of Teams, and internal calls are directly completed through the Teams platform; extensions without Teams accounts register with the SBC platform through hardware SIP phones, and Teams users and original SBC extensions call each other through the SBC Complete the call directly. All Shangjitong lines are connected to the SBC, and external voice calls are connected to the Shangjitong platform through the SBC, and then dialed out through the IMS network, and the local fixed-line number of the area where the site is located is displayed.
