Description:The setup: when one instance of asterisk is a client and other asterisk is a server.

When the client sends REFER without this tag asterisk server returns an error:
SIP/2.0 481 Call leg/transaction does not exist

I will appreciate if someone can explain the reason.

I tested a call transfer with Cisco SPA502G which sends REFER with Replaces value:

Thanks for your comments. This does not appear to be a bug report and we are closing it. We appreciate the difficulties you are facing, but it would make more sense to raise your question in the support tracker, http://www.asterisk.org/support, on the asterisk-users mailing list, or in the Asterisk IRC chat room #asterisk.
