Carrier Registration

This option is only relevant if you are connecting your Carrier to a SIP Trunk (when SBC Onboarding script configures SIP Trunk or BYOC).

Select this option to perform SIP Account Registration for the Carrier trunk:

■ Password: Defines the digest MD5 Authentication password. The valid value is a string of up to 50 characters. Note: The password cannot be configured with wide characters.
■ MainLine (Contact User): Defines the AOR username. This appears in REGISTER From/To headers as ContactUser@HostName
■ Host Name: Defines the Address of Record (AOR) host name. The host name appears in SIP REGISTER From/To headers as ContactUser@HostName.
