MOH on hold an IP networked sites

[Mitelpassion]

Hi,

I'm sure if seen this asked before but I don't seem to be able to find it.

I have two sites, site A and B.
Site A is hosting ISDN for sites B. A call enters site A via ISDN and is routed to site B via IP trunking. Site B's ip phone places a call on hold.

Music on hold from site A is presented and not site B. MOH on site a is external and default moh for site A.

I tried tenanting on site A. uploaded moh file into position 1 and assigned this to Tenant number 2. Assigned tenant number 2 to trunks used for Site B.

Still plays default music on hold for Site A.
any ideas? I have uploaded moh on site B but this never plays when a trunk call is put on hold. Site A's moh plays.

Thanks in advance.
