Using the Easy Configuration wizard to configure the SBC Edge (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. 

The following SIP Trunks are supported:

  • ATT SIP Trunk
  • KDDI SIP Trunk
  • NTT DOCOMO Officelink
  • Other SIP Trunk
  • SoftBank ConnecTalk
