Hi kapil, Thanks for your reply.
I put hq-mrgl(first pub unicast moh, second sub multicast moh) to hq-device-pool, and put hq-device-pool to HQ IP phone & HQ pstn gateway. When the sub and pub moh server work at the same time, I found it play sub if the mgcp pstn gateway registers to sub and it play pub if the mgcp pstn gateway registers to pub. It has nothing to do with the regisration if there is olny one moh server. Thanks.

I can recall, the holder decides which file to play and the holdee decides from which server to take that file from. So if your Gateway MRGL doesn't have access to Pub, it will always try to access MOH from Sub. --- On Mon, 3/30/09, jeffrey liujian <jeffrey_liuj...@yahoo.com> wrote: From: jeffrey liujian <jeffrey_liuj...@yahoo.com> Subject: [OSL | CCIE_Voice] MOH to PSTN To: "Voice CCIE" <firstname.lastname@example.org> Date: Monday, March 30, 2009, 12:38 PM Hi all, I found something weird about MOH. I have a sub moh server for multicast and a pub for unicast. I made a MRGL which put pub first and then sub, and bind it to HQ device pool. I sent moh inside HQ phones it choose unicast(pub) but when I sent moh to pstn it choose multicast(sub). The sub is the primary CCM. What't the reason? I miss somewhere? Thanks. Jeffrey
