[cisco-voip] configure IOS MOH for remote site

Hi Anthony

I need to do exactly the same but could not get it working
immediately. I will go back to the lab again. I suspect it is because
my MOH in multicast mode was not working at my HQ. It was in unicast
mode. I did manage to get the MOH for CME fallback mode working and in
fallback mode it is working but when the site s wan link is up I can
not get MOH - just tone on hold. My branch is using g711 for voice in
the branch and G729 across the wan to HQ. Apart from getting the MOH
at HQ working - are there any special tricks - Do I need MOH at HQ in
G711 or G729 mode or does it not matter - I.E a g729 region for my MOH
to make sure the MOH signalling to fool the phones into listening to
the stream at the branch etc or does it work irrespective of the codec
at HQ.

Another question - the MOH sample file for a branch - is it a G711 or
G729 ??

The one thing that I did was to get the branch going on MOH when in
CME fallback mode (not SRST) is the command where you tie the MOH to a
loopback. I had to also add the fast etehr IP address in the command -
the same address as my cme skinny interface

Hi Goran,
i made it work thanks to you and this link below

http://www.cisco.com/en/US/products/sw/iosswrel/ps5207/products_featur
e_guide09186a00802d1c31.html

but
when i change the .au file for a diferrent audio file, i can't stream
it to the phones unless i reload the router. Is there a way to reset
the music on hold server or something like that?

cheers

	anthony, this MoH is active always at multicast address...not
only for srst.
	that it why you should limit MoH server to one hop...because
we are practicaly cheating it with moh file from flash...
	let me explain:
	when you put someone on hold (ip phone or external caller
trough voice gateway), those devices expect to "hear" MOH on multicast
address (practically, they became memebers fo multicast group).
	So, instead receiveing direct moh from MoH server (remmember,
we limited it on one hop), the devices will hear MOH file from
router's flash which will be played on 239.1.1.1 port 16384 - exactly
where they are listening... :)

	believe me...it works fine for over 50 locations in my
installation :)

	cu,
	goran

		Thanks goran but,
		with this configuration, the MOH server is active only
when srst is active. I want that the MOH server is always active and
so:
		assign this IOS MOH to a media resource group list
that only the specific remote site uses.
		Is this possible?

			this example is for g711 MoH stream to ip
phones.
			at the same time, you should configure one of
the servers in cluster as MoH multicast server but limit it to one
hop.

				Hi all,

				central site: cluster with 2 ccm
4.1(3)sr3a
				remote sites: 3 each with 2851 series
router and srst.
			
				Thanks
