No, because OpenSER, by definition, is not a user agent, but a proxy, and only user agents generate call legs.
There may be a way to fudge it by mangling all the appropriate SIP header features, but it would be almost ontologically contradictory. :-) I ran into this myself trying to loop back calls into a MetaSwitch with some dialed-digit transformations. Ended up having to use a B2BUA like Asterisk.
