[SIPForum-discussion] a question about re-invite

[fanyanping]

Hi all，
my understanding of a SIP reinvite is that it modifies the media session. Is
it capable of modifying the address of the send too? for example， A is
talking to B, can A send a reinvite to B with C's address instead of its own
address?
another example，A is talking to B，recorded as dialog1, C knows the
information of the dialog1,  can C sends a reinvite to B instead of the
dialog1, the dialog bewteen C and B has the same Call-ID, from-tag, to-tag
as dialog1?


Best Regards.
nancy
