An unmanaged gateway is just that. Can I assume that the address for both
systems are on the same subnet? Unmanaged gateways would assume that the
other and knows how to handle the SIP REFER method.

Asterisk as a sip trunking system is not exactly compliant.

If REFER is not supported, then the media needs to be anchored by sipx once
it accepts the call and hold the REFER internally, at which point you would
setup a manual sip TRUNK not a gateway.
