I have the different scenariow. Where as I have CUCM in HQ and two Branches and it centralized deployement, all my IP Phones are registered to CUCM. I want my branch routers to do the MOH from the Branch Router Flash but it is only giving me the moh for the PSTN caller. When an IP Phones calls it is silent. No music is there. Which definately means that it is not taking from CUCM but also not from the router flash.
