Does Multicast MoH works during SRST only? I mean "local multicast"... For example, question says "send multicast MoH to both phones, HQ and SiteB in G711, however multicast MoH should never cross WAN". ----- Original Message ----- From: Alex To: ccie_voice@onlinestudylist.com Sent: Tuesday, November 18, 2008 9:54 AM Subject: Re: [OSL | CCIE_Voice] Multicast MoH from router
An extra bit of information: 1) Checked and found that this feature does not work when H.323 GW is defined as "Non-gatekeeper controlled ICT". Only genuine H.323 GW (from CCM point-of-view) receives MOH from flash.

GRE outer header is unicast so technically multicast never traverses the WAN then.
