The customer is planning to have SME overlay two UCM clusters – one for CCE, and another for “admin” users.
With this scenario, what would we line up Expressway to? Would there be two SIP trunks from Expressway – one for each cluster, or would we do a SIP trunk to the SME server?
The expressway C/E would be needed both for B2B calling, and for Jabber/etc. registration.
Thanks in advance!
