[SIPForum-discussion] INVITE for Redirected calls

[Shakil, Rashid]

Hello,

Quick question please, following is an INVITE for a redirected call. Means original call from PSTN gets redirect to another offnet number. If I am sending this call to a SIP peer can you please tell me which headers (RURI & TO or TO & FROM) are they going to follow to make call category decision (i.e. if the call is Local, Toll, Inter Lata). Means how they rate this call and which headers do they follow. Also can you please reference this from an RFC or any other draft as I was unable to locate the exact information. Thanks in advance for your help...

The details of TN's are underneath the INVITE
