One of my customer is using a Centralized CUCM, with each of the remote gateway acting as a SIP CUBE gateway back to the Service Provider. Each SIP CUBE Voice Gateway also has SRST license (not CME). And my customer is curious on the following:-
Q1. With the SIP CUBE VG and SRST, can each remote Voice Gateway store 1 x MoH and stream out locally to the site phones?
Q2. Since my customer WAN does not support Multicast traffic, would this create a problem on streaming out local MoH?
For the first question you can define a MOH locally on VG (under call-manager-fallback config mode use command "moh flash:somemoh.wav) to use when Phones go in fallback mode only. During normal operations phones will receive MOH directly from CUCM.
For multicast MOH support question, If you don't define multicast on MOH server on the CUCM, your network doesn't need to be musticast enabled.
