Source notes citing this source

• The Set-CsOnlinePSTNGateway ForwardCallHistory parameter makes Direct Routing send History-Info and Referred-By headers to the SBC, and it defaults to $false. in context
• The ForwardPai parameter of Set-CsOnlinePSTNGateway controls whether Direct Routing forwards the P-Asserted-Identity header to the SBC, and it defaults to $false. in context
• Microsoft's disputed statement: according to the Set-CsOnlinePSTNGateway reference, setting ForwardPai to $true 'will render the from header anonymous', citing RFC 5379 and RFC 3325, whereas the Teams caller ID article says that with ForwardPai true the From header still carries the substitute number and CNAM. Neither page says which behavior applies to which calls. disputed in context
