Hi need some advise on IMP federation with Lync 2013.
Customer has a domain eu.xyz.com
Their IMP server's are in a SIP domain of xyz.com.
they have a static route in IMP to legacy LCS server with a pattern of .xyz.com to LCS destination address (using TLS).
They now need to do a federation to a Lync 2013 system which is within their parent organisation which is in xyz.com .
is this possible as an inter domain fed or should it be intra domain? or is it not possible at all due to existing LCS federation ?
TIA...jag
