6202 transfer CID to ext


I was under the impression that “attended transfer” does not allow transfer of caller id. That you had to use BLIND TRANSFER for this to work.

Someone please correct me if I am mistaken on this


Attended is also possible with invite(re-invite) after forward complete.
RFC 3891


hi again.
i read the topic and still not understand if we can keep the cid after att transfer. i am trying to a ucm6204 and 2170 phone but the cid is changing after the att transfer.
can you please be more specific? Is this possible the final destination see the cid of the caller after the att transfer? if yes please confirm.

i have already set the TOS - enable send remote party id.


you must also search and activate the refer on the phone, as well as the correct settings on UCM.
