Expressway to SME

zulfi

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!

Hi,

As per SRND "Each VCS cluster can connect directly to its co-located Unified CM cluster, and calls to other VCS and Unified CM clusters are routed through SME."
