Hi,
No, user=phone should not be added. Only the To tag for the dialog,
which you get in responses, should be added to the ACK (and all other
in-dialog requests).
Regards,
Christer

Subject: [Sip] ACK not matching
Hi,
Is it correct to have "user=phone" added only in ACK's To header
while it is missing in initial INVITE, even though both the messages use
Tel-URI.
Please refer to the trace below:
