[SIPForum-discussion] Proxy can change the From-Tag in the From header?

[Dinesh Rao]

From-tag are added by UAC/UAS.They can't be altered by any intermediate
proxies.Proxies can only add via headers with branch id,record route header
and can alter max-forward header.Rest of all headers are forwarded as it is
to next and neither the sequences of the header in the request are altered.

Thanks
