It doesn't  matter AT ALL if you a a MediaProxy in the same host. Your OpenSer 
(as ANY OpenSer) is transaction stateful, no dialog-stateful.
The only you need is to allow in-dialog messages properly, no more.

There could be 100 reasons for that:
- Bad phones.
- Configure the phones to send the "Refer-To" with the AoR instead of the 
contact address.

Please, don't insist on the fact that OpenSer must do somehting special to 
allow attended transfer. It's not true.

Do a SIP trace to verify what is happening.
