[SIPForum-discussion] Call Forwarding

At the call forwarding scenario:

User-A calls User-B. User-B forwards all incoming calls (call forwarding unconditional) to User-C.

First the INVITE message contains:
	* Request URI: User-B

	* To: User-B

	* From: User-A
Then it changes to
	* Request URI: User-C

	* To: User-B or User-C

	* From: User-A

	* Diversion header: User-B

My question is does "To header" of the changed INVITE contains the forwarded user's number(User-C) of the called number(User-B)? 

Thanks very much for your help,
