Yes it is. This will cause the receiver of the REFER to send an INVITE
for 200@xxxxxxxxxxxxxxxxxxx to the sipXecs box. SipXecs will route that
INVITE the same way it would have if you had made a direct
station-to-station call to 200. One of the benefits of that over
sending the call directly to 200@xxxxxxxx:5061 is that the call will be
forked to voicemail by sipXecs if 200 does not answer.
