First of all sorry for this post not being in the thread it belongs to (I've 
not the initial mail).

You receive a call from Asterisk UAC and want to transfer (blind or attender) 
to other UACregistered in OpenSer.

Of course you don't need Asterisk native transfer, SIP allows blind and 
attended transfer. The only you need is that your SIP devices allow both of 
them (unfortunatelly many SIP devices just allow blind transfer, but in most 
cases reading the device manual you'll find how to do a attended transfer).

The point here is that Asterisk allows receiving a REFER, so don't worry for 
that (I use your same escenary with no problem and SIP transfers).
