Tip

Using the Easy Configuration wizard to configure the SBC Edge Portfolio (SBC) does not modify existing configuration. The wizard will simply add the new configuration elements to the SBC.


The SBC Easy Config interface includes a built-in, step-by-step setup configuration wizard to enable quick and easy deployment of an SBC in a Microsoft Teams environment. 

For SBC 1000/2000 and SBC SWe Edge, the following SIP Trunks are supported:

  • ATT SIP Trunk
  • KDDI SIP Trunk
  • NTT DOCOMO Officelink
  • Other SIP Trunk
  • SoftBank ConnecTalk
  • Softbank White Office
  • Telstra Enterprise SIP Connect 
  • Twilio SIP Trunk
  • Verizon SIP Trunk
Note

The following SIP Trunks are supported in the SBC 1000-2000 only:

  • ATT SIP Trunk
  • KDDI SIP Trunk
  • NTT DOCOMO Officelink
  • SoftBank ConnecTalk
  • Softbank White Office
  • Telstra Enterprise SIP Connect

Depending on the SIP trunk selected, the specific configuration fields are displayed in the Wizard. These are noted below.
