Explanation

Cisco Expressway provides two primary functions relevant here: (A) Endpoint Registration-Expressway acts as a registrar for H.323 and SIP endpoints, allowing devices both inside and outside the network to register and receive calls; and (B) H.323/SIP Interworking-Expressway can translate between H.323 and SIP signaling protocols, enabling interoperability between otherwise incompatible endpoints. Expressway does not provide conferencing or transcoding (those are handled by Cisco Meeting Server or hardware DSP resources), nor does it handle Intercluster Extension Mobility (that is a CUCM feature).
